Quick TakeDon't let the modest 30mm size fool you; this Flagship is a heavyweight in classic style. That sunray black dial is pure, understated class, catching the light just so. Inside, the L592 automatic movement is a trusty workhorse, a smooth-sweeping engine you can glimpse through the back. It’s the perfect daily companion—slips under a cuff, feels solid at 71.1 grams, and stays put with its secure steel bracelet. It’s a piece of quiet confidence for someone who knows quality doesn't need to shout.

DescriptionThe timepiece is constructed from stainless steel, featuring a round case with a precise diameter of 30.00 mm and a thickness of 8.10 mm. The lug-to-lug dimension is 36.40 mm, accommodating a lug distance of 15 mm. Protection for the dial is provided by a scratch-resistant sapphire crystal, which has been treated with several layers of anti-reflective coating on its underside. The case back is transparent, also fitted with sapphire crystal, permitting a view of the internal mechanism. The total assembly weighs 71.1 grams and is engineered for water resistance up to 3 bar. This comprehensive construction ensures structural integrity and functional resilience under specified conditions.

At its core, the watch operates on the Caliber L592, a self-winding mechanical movement that provides hours, minutes, seconds, and a date function. This movement beats at a frequency of 28,800 vibrations per hour and incorporates a monocrystalline silicon balance-spring, offering a power reserve of up to 45 hours. The sunray black dial is appointed with applied indexes and silvered polished hands for clear legibility. The timepiece is secured to the wrist with a stainless steel bracelet, which is fastened by a triple safety folding clasp equipped with a push-piece opening mechanism for enhanced security.
