Reference 2804.52.37

About this watch

The Omega Railmaster 2804.52.37 is a luxury timepiece that embodies the spirit of adventure while remaining rooted in tradition. With its stainless steel case and sapphire crystal, this watch exudes elegance and sportiness, merging the best of both worlds. The black dial with mixed indexes and arrow hands adds a touch of sophistication, making it versatile for both casual outings and formal events. At the heart of this timepiece lies the Omega caliber 2403, an automatic movement that operates on a frequency of 25,200 vibrations per hour and boasts a power reserve of 48 hours. The Co-Axial escapement is a game-changer, enhancing precision while reducing friction, which means less maintenance over time. With its water resistance of 150 meters, it's ready for a dip in the pool or a day out on the boat. This watch is not just about telling time; it's an experience that combines functionality with style.
