Quick TakeThis isn't just another pretty face. Beneath that shimmering mother-of-pearl dial and the subtle flash of 15 diamonds lies the heart of a true adventurer. Its rugged stainless steel case and screw-down back promise durability, easily handling pressures up to 10 bar. You don't need a battery; the reliable Caliber L592 automatic movement inside just keeps ticking with the rhythm of your day. It’s the perfect partner that’s tough enough for a spontaneous weekend trip, yet elegant enough for a candlelit dinner.

DescriptionThe timepiece presents a round stainless steel case construction with a primary diameter of 30.00 mm, a lug-to-lug distance of 37.80 mm, and an overall thickness of 9.70 mm. It has a total weight of 74.6 g. The case is sealed by a screw-down and transparent case back incorporating 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 its upper and lower surfaces. The dial itself is rendered in white mother-of-pearl, appointed with silvered polished hands and diamond indexes. Illumination in low-light conditions is provided by Swiss Super-LumiNova®. The dial is specifically set with 15 Top Wesselton VS-SI diamonds, amounting to a total of 0.037 carats.

Powering the display of hours, minutes, seconds, and a date function is the Caliber L592, a self-winding mechanical movement. This mechanism operates at a frequency of 28,800 vibrations per hour and features a monocrystalline silicon balance-spring, contributing to a power reserve of up to 45 hours. The watch is secured to the wrist by a stainless steel bracelet with a 15 mm lug attachment width. The bracelet is fastened with a triple safety folding clasp that utilizes a push-piece opening mechanism for secure and convenient operation.
