Quick TakeThis isn't just a pretty face, though the deep sunray blue dial sparkling with thirteen diamonds might make you think so. It’s a sleeper. Tucked inside its modest 30 mm steel frame is a workhorse automatic L592 movement, humming with a modern silicon balance-spring. It’s the kind of watch that effortlessly transitions from a business lunch to a weekend getaway, all while feeling solid and surprisingly capable on the wrist. It’s a wink and a nod to classic elegance, backed by serious engineering.

DescriptionThe timepiece, designated L4.374.4.97.6, is constructed from stainless steel, featuring a round case with a diameter of 30.00 mm, a thickness of 8.10 mm, and a lug-to-lug distance of 36.40 mm. The lug width measures 15 mm. A transparent case back, fitted with sapphire crystal, permits observation of the internal mechanism. The primary crystal is a scratch-resistant sapphire, treated with multiple anti-reflective layers on its underside. The total weight of the assembly is 71.3 grams. Water resistance is rated to 3 bar. The sunray blue dial is appointed with silvered polished hands and features 13 Top Wesselton VS-SI diamond indexes, totaling 0.034 carats. The stainless steel bracelet is secured with a triple safety folding clasp incorporating a push-piece opening mechanism.

At its core operates the Caliber L592, a self-winding mechanical movement. This caliber provides indications for hours, minutes, seconds, and a date display. The movement's escapement beats at a frequency of 28,800 vibrations per hour. A key component is its monocrystalline silicon balance-spring, which contributes to its precision and durability. When fully wound, the mechanism maintains a power reserve of approximately 45 hours. The entire system is engineered for consistent and reliable timekeeping, representing a synthesis of traditional horological principles and contemporary material science within a compact and robust architecture.
