Quick TakeThis isn't just a pretty face; it’s a brilliant blend of grit and grace. It’s got the soul of a diver with its screw-down crown and 10 bar water resistance, all while dripping in diamonds. The mother-of-pearl dial shifts in the light, a captivating backdrop for the Caliber L888 movement humming away inside for 72 hours straight. It’s a watch that’s equally ready for a weekend adventure or a rooftop gala, proving that robust engineering and dazzling elegance can, and should, go hand-in-hand.

DescriptionThe timepiece is constructed from stainless steel, presenting a round case with a diameter of 34.00 mm and a thickness of 10.90 mm. The lug distance measures 17 mm, while the lug-to-lug dimension is 41.10 mm. Its total weight is 72.4 g. The case is equipped with a screw-in crown and a transparent, screw-down case back made of sapphire crystal, ensuring water resistance up to 10 bar. Protecting the dial is a scratch-resistant sapphire crystal treated with several layers of anti-reflective coating on both sides. The case itself is set with 48 Top Wesselton IF-VVS diamonds, amounting to a total of 0.403 carats.

At the heart of the watch is the automatic Caliber L888, a self-winding mechanical movement that provides hours, minutes, seconds, and a date function. This movement operates at a frequency of 25,200 vibrations per hour and incorporates a monocrystalline silicon balance-spring, delivering a power reserve of approximately 72 hours. The dial is rendered in white mother-of-pearl and features diamond indexes composed of 14 Top Wesselton VS-SI diamonds, totaling 0.035 carats. Time is indicated by silvered polished hands, enhanced with Swiss Super-LumiNova® for visibility. The watch is secured to the wrist by a white rubber strap, which is fastened with a double security folding clasp incorporating a micro-adjustment system.
