Quick TakeThis isn't just a watch; it's a slice of the night sky for your wrist. The inky black dial is your canvas, with thirteen diamonds sparkling like distant stars. But beneath that elegant face beats the heart of a true performer: the Caliber L888.4 automatic movement. This high-tech engine boasts a silicon balance-spring and a weekend-proof 72-hour power reserve. It's the kind of reliable, sophisticated piece that works as well with a suit as it does with your favorite jeans, a timeless classic with modern guts.

DescriptionThis timepiece is constructed with a round, stainless steel case measuring 40.00 mm in diameter and 10.80 mm in thickness. The lug distance is specified at 20 mm, with a lug-to-lug dimension of 49.60 mm. The total weight of the watch is 120.6 g. Protection for the dial is provided by a scratch-resistant sapphire crystal, which features several layers of anti-reflective coating on its underside. The case back is transparent, also fitted with sapphire crystal, allowing for observation of the mechanism. The assembly ensures water resistance up to 3 bar. The visual interface consists of a black lacquered polished dial, which serves as a background for silvered polished hands. Hour markers are designated by 13 Top Wesselton VS-SI diamonds, with a combined total weight of 0.059 carats.

Powering the hours, minutes, seconds, and date functions is the automatic Caliber L888.4. This self-winding mechanical movement is a certified chronometer, operating at a frequency of 25'200 vibrations per hour. It incorporates a monocrystalline silicon balance-spring and provides a power reserve of up to 72 hours. The watch is completed by a stainless steel bracelet, secured to the wrist with a triple safety folding clasp that incorporates a push-piece opening mechanism.
