Quick TakeThis Hydroconquest GMT craves action! That slick black ceramic bezel isn't just for show – paired with the 30 bar water resistance and screw-down crown, it's ready for serious underwater fun or just tackling the everyday splash zone. Got wanderlust? The GMT hand keeps track of another time zone effortlessly, powered by the trusty automatic L844 ticking away inside with a hefty 72-hour reserve. The sunray black dial with bright lume is sharp and clear, day or night. Plus, the comfy black rubber strap adjusts perfectly. It’s a tough, smart, go-anywhere companion.

DescriptionThe watch features a round case constructed from stainless steel, measuring 41.00 mm in diameter with a lug distance of 21 mm and a lug-to-lug span of 49.40 mm. Its thickness is specified at 12.90 mm. The design incorporates a unidirectional rotating bezel made of ceramic and a screw-down case back, contributing to its structural integrity. Protection for the dial is provided by a scratch-resistant sapphire crystal treated with several layers of anti-reflective coating on both sides. Ensuring operational depth capability, the case includes a screw-in crown and maintains water resistance up to 30 bar. The total weight of the timepiece is documented as 126.8 grams.

Visual elements include a sunray black dial featuring applied indexes as hour markers and silvered polished hands. Swiss Super-LumiNova® is applied for low-light visibility. Internally, the watch is powered by the Caliber L844, an automatic, self-winding mechanical movement operating at 25,200 vibrations per hour and offering a power reserve of up to 72 hours. This movement provides functions for hours, minutes, seconds, date, and incorporates a 24-hour hand with a time zone mechanism. The caliber is also specified as magnetic resistant. The watch is fitted with a black rubber strap secured by a double security folding clasp equipped with a micro-adjustment system.
