Quick TakeThis Hydroconquest nails the sweet spot! At 41mm, it's got presence but sits comfortably thanks to the smart lug design. The green ceramic bezel adds a distinct personality against the classic black dial – tough enough for actual diving with its 30 bar resistance and screw-down features, yet sharp enough for shore leave. Inside, the reliable L888 automatic movement keeps ticking for a solid 72 hours. It’s a robust, no-nonsense tool watch with just the right amount of modern flair.

DescriptionThe timepiece presents a round case constructed from stainless steel, measuring 41.00 mm in diameter with a thickness of 11.90 mm. Lug distance is specified at 21 mm, and the lug-to-lug dimension is 51.10 mm. It features a unidirectional rotating bezel fabricated from ceramic and stainless steel. Protection for the dial is provided by a scratch-resistant sapphire crystal incorporating several layers of anti-reflective coating on both sides. Structural integrity is enhanced by a screw-down case back and a screw-in crown, contributing to its water resistance rating of 30 bar. The total weight of the assembled watch is 183.0 g.

Internally, the watch houses the Caliber L888, an automatic self-winding mechanical movement. This movement operates at a frequency of 25,200 vibrations per hour and offers a power reserve extending up to 72 hours. Standard functions include the display of hours, minutes, seconds, and the date. The black dial features applied Arabic numerals and indexes as hour markers, complemented by silvered polished hands. Visibility in low light conditions is facilitated by the application of Swiss Super-LumiNova®. The watch is secured to the wrist via a stainless steel bracelet equipped with a double safety folding clasp.
