Quick TakeA sleek, 40mm stainless steel case – not too big, not too small – just right. That silver "barleycorn" dial? Pure class. The painted numerals dance with those blued steel hands, like an old-school romance. And get this: a moon phase complication! It is the L899 automatic movement that has a power reserve that lasts days, visible through the back. This watch is old-world charm meeting modern tech. It is built solid, and ready for anything.

DescriptionThe L2.909.4.78.6 model exhibits a circular stainless steel enclosure, measuring 40.00 mm in diameter and 11.10 mm in height. A 21 mm inter-lug width accommodates the stainless steel bracelet, culminating in a triple safety folding clasp incorporating a push-piece release. Total assembly weight is registered at 160.1 grams. Sapphire crystal, treated for resistance to abrasion, protects the dial and is also present on the transparent case back, providing a view to the inner workings.

The timepiece features a silver "barleycorn" dial with painted Arabic numeral hour indices and blued steel hands for hours, minutes, and seconds. A subdial, at the 6 o'clock location, provides a moon phase indication and date. Its functionality is driven by the L899 Caliber, a mechanical self-winding movement. It operates at a frequency of 25,200 vibrations per hour. The fully-wound mechanism provides 72-hour power reserve. This model shows a water resistance rating of 3 bar. The distance, lug-to-lug, is 47.00 mm.
