Quick TakeThis Hydroconquest isn't just telling time; it's telling a story of robust elegance ready for whatever your day—or dive—throws at it. Imagine a watch that’s as comfortable exploring 300 meters underwater as it is paired with a sharp suit. That’s this 41mm two-tone beauty, with its sunray black dial and glowing Super-LumiNova® markers. The automatic L888 heart beats reliably for three whole days, while the sturdy steel and PVD gold construction, complete with a screw-down crown and unidirectional bezel, mean it’s built to last and designed to impress. It's a solid, confident companion on your wrist.

DescriptionThe timepiece presents a round case architecture, fabricated from stainless steel with a yellow PVD coating, measuring 41.00 mm in diameter. Its case back is of a screw-down design, contributing to the overall structural integrity. The lug distance is specified at 21 mm, while the lug-to-lug dimension extends to 51.10 mm. The total thickness of the watch is 11.90 mm. A key feature is its water resistance, rated to 30 bar. Case specificities include a screw-in crown and a unidirectional rotating bezel, enhancing its functional capabilities for dive-related activities. The total weight of the watch is documented as 195.1 grams. The dial is rendered in a sunray black finish, upon which applied Arabic numerals and indexes serve as hour markers. Time indication is achieved via gilt hands, which, along with the markers, benefit from Swiss Super-LumiNova® application for enhanced low-light visibility.

Powering this instrument is the Caliber L888, an automatic self-winding mechanical movement. This movement operates at a frequency of 25,200 vibrations per hour and provides a substantial power reserve of up to 72 hours. The functions delivered by this caliber include the display of hours, minutes, seconds, and the date. The bracelet material mirrors the case, utilizing stainless steel with a yellow PVD coating. It is secured to the wrist by a double safety folding clasp. The watch glass is a scratch-resistant sapphire crystal, which has been treated with several layers of anti-reflective coating on its underside to ensure optimal legibility under various lighting conditions.
