Quick TakeCheck this Hydroconquest out. It's got that classic diver look dialed in – 41mm steel case, tough ceramic bezel, and that slick sunray black dial. You can actually take this deep, 30 bar deep, thanks to the screw-down bits. No glare issues with that coated sapphire crystal either. Inside beats the reliable L888 automatic with a hefty 72-hour power reserve, so it's ready when you are. Plus, the bright lume means you won't lose track of time in the dark. Grippy rubber strap keeps it comfy and secure.

DescriptionThis watch features a round case constructed from stainless steel incorporating a ceramic unidirectional rotating bezel, measuring 41.00 mm in diameter with a thickness of 11.90 mm. The lug distance is specified at 21 mm, and the lug-to-lug dimension is 51.10 mm. Protection for the dial is provided by a scratch-resistant sapphire crystal treated with multiple anti-reflective layers on both surfaces. Ensuring water integrity up to 30 bar, the design incorporates a screw-in crown and a screw-down case back. The total weight of the timepiece is 128.7 g.

The dial presents a sunray black finish, displaying time via applied Arabic numerals and indexes complemented by silvered polished hands. Visibility in low light is enhanced by Swiss Super-LumiNova®. Internally, the watch is powered by the Caliber L888, a self-winding mechanical movement. This automatic system provides hours, minutes, seconds, and a date function, operating at a frequency of 25'200 vibrations per hour and offering a power reserve of up to 72 hours. The watch is secured to the wrist with a black rubber strap equipped with a double safety folding clasp featuring a push-piece opening mechanism.
