About this watch

The Longines Master Collection L2.919.4.51.8 is an exquisite timepiece that blends elegance, functionality, and heritage. With its striking design, automatic movement, and unique moon phase complication, it's more than just a watch; it's a statement of style and sophistication. The black dial features Roman numerals, feuille hands, and a beautiful moon phase indicator that adds a layer of celestial charm. The stainless steel case is robust yet refined, measuring 42mm in diameter and 11.20mm in height. The sapphire glass on top is scratch-resistant, ensuring the watch remains pristine even after years of wear. The alligator leather strap adds a touch of luxury, comfortably wrapping around the wrist. Powered by the Longines caliber L899.2, this automatic movement boasts a 64-hour power reserve, making it reliable and precise. With features like hours, minutes, small seconds, date, and moon phase, this watch is not just about telling time; it's about experiencing time. The water resistance of 30 meters allows for everyday activities, but keep in mind it's not designed for diving or swimming. This masterpiece from Longines is perfect for individuals who appreciate traditional craftsmanship coupled with modern technology.
