The Longines L3.843.4.96.6 HydroConquest Quartz Chrono is a professional-grade dive watch that merges Swiss precision with rugged durability. Designed for water sports enthusiasts and adventure seekers, it offers a uni-directional rotating bezel, luminous markers, and a 1/100th second chronograph function. Powered by the Longines Caliber L440 quartz movement, this timepiece delivers high accuracy and low-maintenance reliability.

Why It Stands Out

The Longines HydroConquest Quartz Chrono is celebrated for its bold design and professional dive capabilities. With a striking blue dial and bezel, a stainless steel bracelet, and a 300m (1000ft) water resistance rating, it is built to withstand demanding environments. The 1/100th second counter and three sub-dial chronograph layout enhance its precision, making it ideal for timing events both on land and underwater.

Case & Dial

The watch features a 47mm stainless steel case, providing a commanding wrist presence. The blue dial and bezel enhance its sporty appeal, while the luminous dot hour markers and hands ensure readability in low-light conditions. The sapphire crystal with anti-reflective coating adds scratch resistance and clarity.

Strap & Comfort

Fitted with a stainless steel brushed and polished bracelet, the watch offers both durability and a premium feel. The folding clasp with a safety latch ensures a secure fit, making it comfortable for extended wear.

Movement and Performance

At the heart of the Longines L3.843.4.96.6 is the Longines Caliber L440 quartz movement, known for its exceptional accuracy.

The chronograph function features:

Large red central seconds counter
1/100th second counter
30-minute sub-dial at 2 o’clock
12-hour sub-dial at 10 o’clock
Running small seconds sub-dial at 6 o’clock

The date function is positioned at 4 o’clock, ensuring additional practicality.

Everyday UsabilityWith its 300m water resistance, the watch is well-equipped for swimming, snorkeling, and professional diving. The screw-down crown and solid case back add durability, while the uni-directional rotating bezel allows for precise dive timing. The luminous elements further enhance legibility in dark conditions.

Final Thoughts

The Longines L3.843.4.96.6 HydroConquest Quartz Chrono is a versatile and high-performance sports watch. Combining a bold 47mm case, accurate quartz chronograph, and professional dive features, it is perfect for those who demand both functionality and style in extreme conditions. Whether for diving, sports, or everyday wear, this Longines timepiece delivers exceptional value.
