Quick TakeThis isn't just another watch; it's a proper companion. At a perfect 38mm, its steel form sits comfortably, ready for anything. The sunray black dial offers a subtle flash, equally at home under a cuff or a jacket sleeve. But don't let the good looks fool you—with a screw-down crown and 10 bar water resistance, it’s built to handle real life. The powerhouse L888 movement keeps ticking for a full 72 hours, so it's always ready to go. That clever micro-adjust clasp on the rubber strap? Pure comfort. It’s the one you’ll keep reaching for.

DescriptionThe timepiece is constructed from stainless steel, formed into a round case with a diameter of 38.00 mm and a thickness of 10.90 mm. The lug-to-lug dimension is 46.80 mm, with an inner lug distance of 19 mm for strap integration. The case is methodically sealed by a screw-in crown and a screw-down transparent case back fitted with sapphire crystal, a configuration ensuring water resistance to 10 bar. Protecting the dial is a primary scratch-resistant sapphire crystal, which has been treated with several layers of anti-reflective coating on both its upper and lower surfaces. The total weight of the complete assembly is registered at 96.0 g.

A sunray black dial serves as the backdrop for applied indexes and silvered polished hands, with all relevant indicators treated with Swiss Super-LumiNova® for enhanced low-light legibility. Timekeeping is governed by the Caliber L888, a self-winding mechanical movement that provides central hours, minutes, seconds, and a date complication. This mechanism operates at a frequency of 25,200 vibrations per hour and incorporates a monocrystalline silicon balance-spring for improved stability and performance, offering a continuous power reserve of up to 72 hours. The watch is secured to the wrist by a black rubber strap, which is fastened with a double security folding clasp that features an integrated micro-adjustment system for a precise fit.
