The Hamilton Khaki Field King Auto in its black PVD “stealth” configuration combines classic military field watch heritage with modern specs and style. Notable for its fully spelled-out day-of-week indicator prominently arced below 12 o’clock and a date window just beneath, the Khaki Field King stands out among field watches[1][2]. This 40 mm Swiss-made timepiece features a rugged black dial with bold white Arabic numerals (12-hour scale and inner 24-hour markings) and luminous hands/indices for high legibility in all conditions. It’s an “impressively affordable” automatic watch given its build quality and heritage, making it popular as a versatile daily wearer that “looks good equally in the boardroom, pub or out in the countryside,” according to one owner[3].
1. Technical Specifications
The Hamilton Khaki Field King Auto (ref. H64465733) is a robust mechanical field watch with a day-date complication. The table below summarizes its full technical specifications:
Specification | Details |
Movement | |
Functions | Time (hours, minutes, central seconds); Day of week (fully spelled) at 12 o’clock; Date at 12 o’clock (just below day window)[6]. |
Case | |
Crystal | |
Dial | Black dial with white Arabic numerals (1–12) and inner 13–24 hour scale for military time[14]. White minute indices with luminous dots at hour marks. Day–Date: Two-window display at 12 o’clock (day arcs along top, date numeral below) – a signature of the “King” design[15]. Brand logo and “Khaki Automatic” text on dial. |
Luminous | Super-LumiNova on hands and hour numerals for a bright green glow in the dark[2]. Both the large sword/syringe hands and the printed numerals are lume-filled, aiding low-light legibility (see image below). |
Case Back | |
Water Resistance | |
Strap/Bracelet | |
Additional | Heritage design: Dial layout inspired by mid-20th-century military spec field watches (12/24h dial, triangular 5-minute markers, etc.)[24]. Crown: Signed crown at 3 o’clock, flanked by protective shoulders. Weight: Moderate, ~ (not specified, but described as comfortable/light on bracelet)[25]. Warranty: Typically 2-year international warranty (manufacturer). |
The Caliber H-40 movement is a highlight – essentially an upgraded ETA with a lower beat rate and extended mainspring, giving ~80 hours of running time[26]. This means you can set the watch down on Friday and it will still be ticking by Monday[27]. The day and date complication is quickset via the crown’s first position (date set forward, day set backward)[28]. Overall, the watch’s build and specs reflect its military roots (sturdy steel case, easy-to-read dial, decent water resistance) combined with modern conveniences like the sapphire crystals and display back.
2. Pricing and Availability
Retail Price: The official Hamilton list price for the Khaki Field King Auto ref. H64465733 is \$845 USD (as of 2025)[29]. In some regions, the MSRP is around €645 in Europe[30] or ~£740 in the UK (on leather strap). Hamilton’s own website and boutiques often sell it at full retail, with this model currently in the current collection and listed “In stock” on Hamilton’s site[31].
Market Street Price: Being widely available, the Khaki King can often be found at a discount through authorized dealers or grey-market retailers:

3. Reviews and User Reception
The Hamilton Khaki Field King has garnered positive reviews from both professional watch media and everyday owners. Below we break down the general consensus:
Expert Reviews and Impressions
Professional reviewers often praise the Khaki Field King for offering a great mix of value, heritage, and functionality. Notably:
aBlogtoWatch (Hands-On Review, 2021): Ariel Adams noted the Field King is “an impressively affordable mechanical model” given its features, highlighting the fully-spelled day-of-the-week display as a unique trait in this price segment[1]. The review (which was of this exact reference) applauded the robust 80-hour movement and classic styling, while also mentioning the ~50 mm lug-to-lug size and ~11 mm thickness that make for a substantial but still comfortable wrist presence[9]. The only caveats were minor: the cut-off numerals at 11 and 1 o’clock (necessary to accommodate the day window) might irk purists who prefer an untouched dial design, but this is a subjective point.
Fratello Watches (Hands-On, 2020): Fratello’s reviewer loved the “stealthy” all-black look, stating that the black PVD coating and matching black dial give it a more modern, tactical feel compared to the standard steel models[40][41]. They note the military heritage behind the design – the watch is inspired by Hamilton’s 1940s field watches, but in a contemporary 40 mm size. The piece highlights how legible the dial remains despite packing a lot of information: “There is quite a bit of information on the dial, but it doesn’t impede a nice and clear overview of all functions,” thanks to the high-contrast white on black and logical layout[42][43]. Both the large polished sword hands and the Arabic numerals are lumed and stand out well against the matte dial[43][44]. Fratello also confirms the movement is based on the ETA 2834-2 day-date caliber and operates at 21,600 vph with 80h reserve[4]. They found the 40 mm case “perfectly sized” for a broad audience and only had a reservation about the cutoff of the ‘1’ and ‘11’ numerals by the day window – a cosmetic quirk that some dislike[45]. Overall, they conclude it’s a “great affordable watch” that can handle semi-formal to outdoor wear easily[30]. The reviewer’s only immediate change would be swapping the stock black leather strap for something like a suede or NATO to add contrast or color[46], implying the supplied strap is adequate but perhaps a bit too monochromatic for their taste.
Gnomon Watches (Product Review, 2020): Gnomon (a retailer) published a detailed description praising the “tactical field watch” character of this black PVD variant[47]. They emphasize Hamilton’s military watch legacy (supplying the US forces in World War II, Vietnam, etc.) and how the Field King Auto pays homage to that with its dial and durability[48][47]. The review notes the monochromatic black-on-black styling is not just for looks but also historically in line with military needs for non-reflective, camouflaged gear[47][49]. In terms of build, Gnomon calls the 40 mm case “versatile” in size (they measured ~11.3 mm thick) and the satin-brushed PVD finish “pretty badass,” giving the watch distinct character[50][51]. They also laud the dial layout: the white printed numerals and 24h inner ring are “essential for military timing operations,” and the syringe-shaped hands are designed such that the hour hand neatly points to the 24h indices and the minute hand reaches the outer minute track[52]. The luminescence is described as bright and satisfying, using modern Super-LumiNova instead of the tritium paint of vintage times[2]. Like others, Gnomon highlights the day-date at 12 as a hallmark of this model, “cleverly situated… retaining the dial’s legibility and symmetry,” since it centers the complications in a unique way[2][15]. They confirm the movement’s specs (modified 25-jewel ETA with 3 Hz beat and longer power reserve) and mention that the lower frequency can enhance longevity due to less friction[16][53]. They also point out the crown is knurled and protected by the case flanks, and the exhibition back shows Hamilton’s decorated rotor[16]. In all, the Gnomon review positions this watch as a “stunning option for those seeking a stealthy tool watch that retains design elements from [Hamilton’s] legendary mil-spec field watch”[54].
Overall, expert reviews commend the Khaki Field King for its legibility, reliable movement, build quality for the price, and distinctive day-date display. Criticisms are minor: the lack of AR coating on the crystal (meaning the sapphire can be reflective in some angles)[13], and the aesthetic issue of truncated numerals. Both are common trade-offs in watches at this price and style. Importantly, the watch’s heritage is frequently mentioned – it’s seen as an authentic descendant of Hamilton’s military watches, which adds to its appeal for enthusiasts.
User Reviews and Owner Feedback
Owners of the Khaki Field King, across forums, retailer sites, and social media, are overwhelmingly positive about the watch. Several key themes emerge from user feedback:
Versatile, Everyday Wear: Many owners use the Khaki King as a daily watch. On Reddit and watch forums, users report wearing it in all settings – office, casual, outdoors – and praise that it “works with any outfit without being ostentatious”[55][56]. One Redditor even said if they had to have a one-watch collection, this would be it, given how balanced it is for daily use[57]. Owners on FirstClassWatches (a UK retailer) similarly comment that it’s “a functional piece of kit that could also be used in a 'dress' capacity,” noting the design is clean enough for semi-formal wear but tough enough for casual use[58]. The versatile 40 mm size and classic styling get credit for this adaptability.
Quality & Value: Numerous buyer reviews call out the excellent quality for the price. One verified purchaser wrote: “Simple lines and fantastic build quality mean the Hamilton Khaki King Auto is going to be one of my favourite go-to watches. Accuracy and power reserve are fantastic.”[3] Another noted theirs runs at +2 seconds/day, comparing that favorably to far more expensive watches[59]. The finishing (e.g. brushed case, dial printing) and the inclusion of a sapphire crystal and display back at this price point are often appreciated. In summary, users feel they got a lot of watch for their money – “very good workhorse ETA movement and the day-date complication is very useful… the quality is there,” wrote one owner, rating it 5/5 on multiple factors[60]. Several were “flabbergasted” at the value, given it’s a Swiss-made watch with an 80-hr movement at well under \$1000[61].
Heritage and Design: Owners who did their research often mention Hamilton’s military lineage as a selling point. A review from 2017 mentions “I needed one that was easily legible… I then happened upon the Hamilton range and the Khaki King fitted my requirements exactly… The watch face is very well laid out. All the numbers and day/date are very clear with very little reflection. Ideal for my eyes.”[62] This captures how the classic field watch design (high contrast dial, anti-reflective needs) was a major draw. Many love the look of the watch – the black dial with white numerals and the unique day arc has character. Some specifically sought out the fully spelled day feature because it’s reminiscent of the Rolex Day-Date “President” (albeit on a rugged field watch)[63]. The nickname “King” itself appeals – Hamilton markets it with the phrase “Long live the king,” emphasizing it as a flagship of the Khaki Field line[11].
Comfort & Size: Owners with medium wrists (around 6.75" ~ 7") find the 40 mm case a good fit – though a few note the long lugs. One buyer pointed out “the lugs are quite long but are curved for a great fit”, and ultimately said it wears very well on his 6.75″ wrist[64]. The watch is not too heavy; a user with the bracelet version mentioned the bracelet is “light but solid” which made it comfortable[65]. The curved lugs and 20 mm strap width allow it to hug the wrist nicely. There’s also positive mention of the watch being relatively slim: “Really thin for an automatic” one reviewer wrote[13] (11 mm thick is indeed fairly slim, aided by the curved crystal and caseback design).
Strap/Bracelet: Opinions on the stock strap are decent, but many owners enjoy swapping straps on this watch. The 20 mm lug size and military style lend themselves to NATOs, canvas straps, or vintage leather. A Hamilton buyer noted they “bought an additional strap to complement my wardrobe… Love how easy it is to change the straps, and Hamilton sent me the needed tool for free”[23]. This reflects the watch’s strap versatility. Meanwhile, those who got the bracelet version (available on the non-PVD model) often praise the bracelet quality “well worth the price”[22], saying it elevates the look. A common piece of advice is to buy on the bracelet if possible (for value), then purchase aftermarket straps for variety[66].
Lume and Legibility: Users report that the Super-LumiNova lume on the hands and numbers is quite strong. One commenter noted “the luminous on the hands is nice and bright in the dark. For the price I was surprised to note the numerals glow as well”[67]
In practice, the watch’s dial is praised for being extremely easy to read at a glance – large numerals and well-proportioned hands ensure that. Even the 24-hour markings are readable but subdued enough not to clutter the dial. The day and date being at 12 means no standard date window at 3 or 6 to disrupt the symmetry; several owners actually like this symmetrical layout (while a few, as mentioned, don’t love the cut numerals at the top).
Accuracy & Performance: Many owners comment that the watch keeps very good time. Hamilton regulates the H-40 pretty well from factory; reports of +2 to +5 seconds per day are common, which is excellent in this price class[59]. The extended power reserve is a huge plus in user eyes – they notice they can put the watch down for a couple days without it stopping. One owner mentioned being initially drawn by the 80-hour spec as a unique selling point, and was not disappointed by its performance[68].
In aggregate, user reception underscores that the Khaki Field King meets or exceeds expectations for a watch in its ~$600 range. It delivers on the promises of durability, legibility, and a touch of uniqueness (the day-date display) that attracted buyers in the first place. The watch has an average rating around 4.8–5 stars across various retailer reviews[69][70]. Complaints are rare; aside from an owner wishing for AR coating on the crystal to reduce glare[13], there’s little negative to report. Even the PVD coating’s durability has been good so far – no chipping or excessive wear reported in the first few years by those who own the black version (regular wearing, of course, will eventually show edge wear on any PVD, but Hamilton’s quality seems solid).
Notable Appearances
As an aside, the Khaki Field King has made a few pop culture appearances. Hamilton watches are known for product placements, and the Khaki King (steel model on leather) was actually worn by Hugh Laurie’s character, Dr. Gregory House, in Season 8 of the TV series House M.D.[11]. This tidbit is mentioned by Hamilton, further cementing the watch’s image as a versatile “everyman’s” watch that even a maverick doctor on TV would wear. Such appearances have also introduced the watch to new fans. (Hamilton in general has a strong association with Hollywood and military films due to its heritage.)
4. Design and History
Lineage: The Khaki Field King is part of Hamilton’s broader Khaki line, which is deeply rooted in the brand’s military watch heritage. Hamilton, originally an American company, supplied timepieces to U.S. troops during World War I, World War II, and the Vietnam War[71][72]. The classic “field watch” design – black dial, clear white numerals, and rugged simplicity – was born from those mid-20th-century military specifications (e.g. the MIL-W-3818 and MIL-W-43674 standards). Today’s Khaki Field models channel those original GI watches, with modern updates. The Khaki Field King specifically builds on the field watch template by adding the day-date function.
“King” Features: What distinguishes the Khaki Field King from the standard Khaki Field Auto is primarily the day display at 12 o’clock (in addition to the date). In fact, Hamilton’s literature calls it a “different take” on the day-date than most watches, as the day is shown in an arc at the top (somewhat reminiscent of the Rolex Day-Date President layout)[73]. This design choice gives the watch its nickname “King,” implying it’s the king of the field watch line with the full day complication. The day disc shows the entire word (e.g. “WEDNESDAY” as seen in images), which adds character – a feature less commonly found on field/military watches, which historically prioritized simplicity. Hamilton managed to include it without losing the military style: the day aperture cuts into the “11” and “1” positions but is centered under the 12 o’clock marker, maintaining symmetry.
Another notable design element is the addition of crown guards. Many traditional field watches (like Hamilton’s 1960s models or the modern 38 mm Khaki Mechanical) have an exposed crown. The Khaki King’s case has flared shoulders around the crown, offering protection against knocks[74]. These protectors were “specially designed to ensure the safety of the crown at all times” as Hamilton puts it[11]. They blend into the case silhouette, enhancing the watch’s robustness and giving it a slightly more modern look compared to completely vintage-inspired pieces.
Aesthetics and Dial: The dial is quintessential field watch – matte black (reducing glare), with sans-serif Arabic numerals for hours and a smaller inner ring for 13–24 hours (military time)[52]. This dual-scale dial directly harks back to issued military watches (for example, U.S. Army watches in the Vietnam era often had this layout: 12-hour and 24-hour markings[24]). At each hour is a small lume dot and a triangle marker at 12, again echoing mil-spec designs for orientation in the dark[24]. The hands are polished steel, shaped as pointed swords (also described as syringe-style due to the fine tips), with generous lume fill. The minute and second hands reach out to a neat minutes track at the very edge, which has bold markings every 5 minutes and tiny marks per minute, aiding precise reading.
Despite the additional complications, Hamilton kept the dial uncluttered and highly legible. The brand name and “Khaki Automatic” text are modestly sized at the center. The day and date windows are integrated at 12, arguably preserving symmetry better than a 3 o’clock window would. As noted by Gnomon, positioning the calendar at 12 o’clock was clever for retaining legibility[15] – your eye reads the day/date together at the top without disturbing the flow of reading time.
Case and Build: The case of H64465733 is stainless steel with a black PVD coating (PVD = Physical Vapor Deposition, a hard wearing coating). The finish is mostly brushed, giving a low-reflection, tactical look (glossy/polished surfaces are minimal, mainly just a bevel on the bezel edge for a slight highlight). This matches the “stealth” concept – no shiny surfaces to catch the eye in the field[47][49]. Even the Hamilton “H” on the crown is blacked out. The watch has a slightly domed sapphire crystal on the front and a flat sapphire on the back. The display back shows off the movement, which, while an undecorated workhorse, does have a custom rotor with Hamilton’s logo and some striping[16]. It’s a nice touch for enthusiasts who enjoy seeing the mechanical internals at work.
Military Heritage: In terms of history, the Khaki Field King pays homage to Hamilton’s 1940s and 1950s field watches. Those were typically 30–34 mm, hand-wound, and built to U.S. Army specs (Hamilton was famously one of the few suppliers for issued watches). The modern Khaki line resurrects the name “Khaki” which Hamilton started using for civilian reissues in the 1980s[75]. The Field King isn’t a direct reissue of a single vintage model but rather a modern evolution. The fully spelled day is actually more reminiscent of mid-century dress watches (and of course the Rolex Day-Date from 1956) than of Hamilton’s own mil-spec watches. However, Hamilton did produce Day-Date automatics for civilian use in the late 20th century that could be seen as predecessors to the King.
Within Hamilton’s lineup, the Khaki Field King sits alongside simpler Field models and more specialized ones. It appears that Hamilton introduced the “King” variant to offer something for those who wanted a day function – hence “king” as in the top of the line with all the calendar features. The reference H64455533 (non-PVD steel, black dial) has been in the catalog for quite some time and is notably the watch worn by Dr. House in 2012 as mentioned[11]. So the design at least dates back over a decade. The black PVD “Ops” edition (H64465733) is a newer iteration (circa 2020), adding the trendy all-black look to the proven design[49][76]. This was likely done to appeal to a younger or more style-conscious demographic, and to align with the popularity of “black-out” tactical watches.
In summary, the Khaki Field King design merges vintage military aesthetics – easy-to-read layout, 24-hour scale, rugged case – with a contemporary twist of the day/date and PVD styling. Hamilton’s long military watch legacy is clearly referenced (the watch is often marketed alongside images of soldiers or mentions of its predecessors[24]), giving owners a sense of history on the wrist. Yet it doesn’t feel outdated; on the contrary, elements like the 40 mm size, exhibition caseback, and sleek black coating make it very much a modern timepiece that nods to the past.
5. Comparable Watches and Alternatives
The field watch genre is popular, and there are several alternatives in the same price bracket that one might consider alongside (or instead of) the Hamilton Khaki Field King. Below is an overview of similar watches – including other Hamilton models and offerings from reputable competitors – that share some characteristics (mechanical movement, casual field/military style, day-date or similar functions, and roughly \$200–\$1000 range):
Watch Model | Key Specs & Features | Price (USD) |
Hamilton Khaki Field King Auto (Steel)<br>Ref. H64455533 | Essentially the same watch as H64465733 but in natural stainless steel (no PVD). Black dial, day-date at 12, 40 mm case with crown guards. Ships on brown or black leather, or bracelet. Offers identical 80h H-40 movement and specs. This is the classic non-coated variant and was featured on House M.D.[11]. | \$745 MSRP on leather[77] (street ~$600). |
Hamilton Khaki Field Automatic (42mm) | A simpler cousin in the Khaki line – no day complication (date-only), but larger 42 mm case. Uses the H-10 automatic (80h, no day wheel). Available in steel or PVD, various dial colors. If one prefers a cleaner dial or larger size, this is an option. Water resistance is slightly higher on some (100 m in certain variants). | \$575–\$695 MSRP (depending on strap/bracelet)[39]. Street price ~$500. |
Hamilton Khaki Field Mechanical (38mm) | The purist’s field watch: 38 mm steel case, hand-wound H-50 movement (80h). No date or day at all – just time. Vintage military reissue design with old-style lume options (e.g. faux patina). Great for smaller wrists or those wanting a true WWII-style throwback. Very light and manual-wind charm, but lacks the convenience of day/date. | \$575 MSRP on strap (often less online). |
Hamilton Khaki Aviation Pilot Day Date (42mm) | Another Hamilton day-date model, known for being worn in the movie Interstellar. 42 mm steel case, day at 12 and date at 6. More of a pilot watch aesthetic (large cathedral hands, vintage font numerals). Shares the H-40 movement. If you like Hamilton’s day-date but prefer pilot styling or a larger size, this is a strong alternative. | Around \$945 MSRP on leather[4] (street ~$800). |
Seiko 5 Sports “Field” Series (40mm, e.g. SRPG27) | A highly affordable automatic field watch. Day-Date display at 3 o’clock, 39–40 mm steel case, 100 m water resistance. Runs on Seiko’s in-house 4R36 (approx. 41h reserve, 21,600 vph). Dial design is clearly field-inspired (12/24h markings). Hardlex (mineral) crystal instead of sapphire. Offers a similar military look and day-date functionality at a fraction of the cost, though with some compromises in materials and finishing. | |
Orient Defender 2 (42mm) | Orient’s take on a modern field watch. 42 mm steel case, in-house Orient automatic movement. Rather than a classic day window, it features a day subdial (at 10 o’clock) and date at 6, plus a 24-hour indicator – a different layout. 100 m water resistant. A bit larger and busier dial, but offers robust specs and a military style. | \$225–\$300 range (very strong value). |
Citizen BM8180 “Eco-Drive Field” (37mm, quartz) | A popular entry-level field watch. 37 mm steel case, black dial with day-date at 3. Uses Citizen’s Eco-Drive solar quartz movement (no battery changes). Fabric strap. While not mechanical, it’s a tough, inexpensive field option with the same functionality (day & date) and smaller size. | ~\$130 (street). |
Marathon General Purpose Field Auto (39mm) | A Canadian-made mil-spec field watch, 39 mm fiber-shell case or steel (depending on model), automatic movement (Sellita SW200, ~38h). No day window – date only (or no date in some). The dial uses tritium gas tube lume for constant glow. 30 m water resist (historically intended as disposable issue watches). Suitable for true military enthusiasts – very utilitarian. | \$450 (resin case version) to \$1000 (steel with tritium). |
Luminox Atacama Field Automatic (44mm) | Swiss-made field watch with day-date at 3. Bigger at 44 mm, designed for rugged outdoor use. Houses a Sellita SW220 auto (day-date, 38h). Notably uses tritium tube lume for constant visibility. 200 m water resistance, sapphire crystal. If one wants a larger, very tough day-date field watch and doesn’t mind the size/premium. | \$900 – \$1,100 (varies by model line). |
Ball Engineer III / Fireman (40mm) | Ball Watch Co. offers several models with a similar vibe: 40 mm stainless steel, often with day-date (at 3 o’clock) and 100 m WR. They feature tritium lume and very high build quality, with COSC-grade movements. The Ball Fireman Day Date, for instance, is another “railroad”/field style watch from a heritage brand. Downside: significantly more expensive than Hamilton. | ~$1,000 to $1,500 (Ball Fireman NightBreaker Day-Date ~\$1,300). |
Tissot Gentleman Powermatic 80 (40mm) | A more dressy alternative from another Swatch Group brand. 40 mm steel case, Powermatic 80 movement (same base tech as H-40, 80h reserve). Only a date (no day), and a more polished design (applied indices, etc.). Included here as another Swiss 80h automatic around the same price, if day function isn’t a must. | \$775 MSRP (street ~$600). |
Mido Multifort Day-Date (42mm) | A sporty Swiss automatic with Geneva-striped dial, day-date at 3, and 100 m WR. Uses the day-date variant of Powermatic 80. More of an urban/dressy style but comparable specs. | \$1,000 MSRP (often ~$800 street). |
Seiko Prospex “Baby Alpinist” (SBDC137) (38mm) | A higher-end Seiko mechanical field/pilot style watch. 38 mm steel case, sapphire crystal, 70 m WR. Features a day indicator (pointer hand indicating day on inner dial) and date at 3. Powered by 6R35 (70h reserve). Not a direct day-window watch, but an interesting twist on day display. | ~$700–\$750 (Japan import model). |
(Prices are approximate and subject to change; listed to give a general idea of market segment.)
As seen above, the Hamilton Khaki Field King holds a strong position in its segment. Few competitors offer the fully spelled-out day at this price point in a mechanical watch. Seiko’s autos have day windows, but typically abbreviated (e.g. “WED”). Many Swiss brands in this range focus on either just date (Tissot, Longines) or move upmarket for day-date (Ball, etc.). Hamilton itself provides alternatives if the day function isn’t critical – e.g. the 38 mm hand-wind for a more vintage feel, or the larger Pilot Day Date for a bolder look.
For someone specifically drawn to the Khaki Field King’s military style and day-date functionality, the closest alternative within Hamilton is simply the different variants of the King (different colorways or quartz version). Outside Hamilton, Seiko 5 Sports models are the budget choice, whereas something like the Ball Fireman or Luminox would be a more heavy-duty but pricier route.
