The Movement: A Humming Innovation

At the heart of the 198.0024 is the Omega Caliber 1250, based on ESA’s 9162 tuning fork movement. This 12-jewel marvel runs at 300Hz, replacing the traditional balance wheel with a vibrating tuning fork, resulting in a smooth-sweeping seconds hand and a distinctive hum. This design, derived from Bulova’s Accutron, was certified chronometer-grade and boasted excellent accuracy for its time.

Though eventually eclipsed by quartz technology, the f300Hz movement offered a bridge between mechanical tradition and electronic future—a rare hybrid that’s now appreciated for its uniqueness and technical ingenuity.

The movement emits a gentle hum that’s unmistakable and a true delight for collectors. It also features a quickset date mechanism and hacking seconds for ease of use, though it requires specific knowledge and parts for servicing. Despite these caveats, many owners find its charm well worth the care.

Design: Sleek, Integrated, and Undeniably 70s

The Constellation 198.0024 showcases a clean, geometric case with no traditional lugs. Instead, the integrated stainless steel bracelet flows seamlessly into the tonneau-shaped case, exemplifying 1970s design. The dial is minimalist yet functional, featuring a silver sunburst finish, date window at 3 o’clock, and signature Omega and “f300Hz” markings.

The case back carries the Constellation’s hallmark observatory medallion, and the crown, subtly recessed, completes the sleek profile. The watch wears compact yet substantial, thanks to the integrated bracelet and case width.

This aesthetic reflected a broader movement in 1970s watch design—towards bold, modern shapes and integrated architecture. As a result, the 198.0024 remains an appealing option for those who appreciate vintage style with substance.

A Short-Lived Era

Produced around 1972–1975, the 198.0024 was part of Omega’s relatively brief tuning fork experiment. While the technology was impressive, it was soon overtaken by quartz movements in affordability and performance. Consequently, production numbers were limited, making these models rarer than many mechanical Constellations of the same period.

This watch served as a symbol of Omega’s willingness to innovate, even in uncertain times, blending the brand’s luxury chronometer legacy with modern, electronic flair. It’s a watch that stood at the crossroads of horological history—honoring the past while attempting to master the future.

Market Value & Variants

Today, the stainless steel version of the Constellation f300Hz typically ranges between $500–900 USD, depending on condition and completeness. Gold-capped versions fetch slightly more, while solid 18K gold models can exceed $5,000 due to intrinsic metal value.

Material	Reference	Dial Color	Estimated Price
Stainless Steel	198.0024	Silver	$500–900
Gold-Capped	198.0022	Champagne	$700–1,000
18K Gold	198.0022	Champagne	$5,000+

Collectors should look for examples with original bracelets and minimal dial wear. A humming movement and intact observatory case back medallion also enhance desirability. Watches with original boxes, papers, or Omega extract of the archives command a premium.

Servicing a tuning fork movement requires a specialist, and while parts are still available, it's advisable to consult watchmakers familiar with these calibers. Battery replacements are straightforward, but delicate internal components demand expert handling.

Collectibility and Final Thoughts

The Omega Constellation 198.0024 may not be the best-known model in Omega’s vast catalog, but it is undoubtedly one of the most fascinating. For collectors, it represents a unique blend of heritage and innovation—a watch that literally hums with history.

With rising interest in 1970s design and electro-mechanical watches, the 198.0024 offers not just a glimpse into a transitional time but a wearable piece of horological evolution. For those seeking an affordable, stylish, and technically intriguing Omega, this Constellation is a stellar choice.

It's also a perfect conversation starter—unusual, handsome, and quietly iconic. As more collectors rediscover the charm of these early electronic marvels, the Constellation 198.0024 is well-positioned to become a cult classic in vintage watch circles.
