Quick TakeThis is a true flyer's watch for the grounded individual. It wears its 40mm steel case with confidence, a solid tool that feels just right. The stark, matte black dial isn’t trying to be flashy; its job is to tell you the time, day or night, with a quick glance at those luminous numerals. But the real story is the engine inside—a powerhouse automatic with a 72-hour gas tank and a cutting-edge silicon balance-spring. It’s a dependable co-pilot with a pioneering soul, built to handle your journey with precision and class.

DescriptionThe case of the L3.810.4.53.6 is fabricated from stainless steel into a round shape, with a primary diameter of 40.00 mm and a lug-to-lug distance of 49.70 mm. The overall thickness measures 12.20 mm, and the lug width is specified at 21 mm. Structural integrity is enhanced by a screw-in crown, which helps secure the water resistance rating of 10 bar. The total weight of the timepiece is 142.4 grams. Protecting the dial is a scratch-resistant sapphire crystal, which has been treated with several layers of anti-reflective coating on both sides to minimize glare. The display features a black matt dial with applied Arabic numerals as hour markers and silvered sandblasted hands. Swiss Super-LumiNova® is applied for legibility in low-light environments.

Powering the watch is the Caliber L888.4, a self-winding mechanical movement that provides indications for hours, minutes, seconds, and date. The movement operates at a frequency of 25,200 vibrations per hour and is distinguished by its monocrystalline silicon balance-spring, which offers resistance to magnetism and temperature variations. A substantial power reserve of up to 72 hours is provided. The watch is affixed to the wrist with a stainless steel bracelet that integrates a triple safety folding clasp, complete with a push-piece opening mechanism for secure and convenient operation.
