This vintage Omega Seamaster Diver 300M ref. 2552.80.00 is the midsize version of one of Omega’s most iconic dive watches. Its 36 mm stainless steel case is paired with the signature blue unidirectional bezel and a striking blue wave-pattern tritium dial, whose luminous indexes and hands have developed a desirable natural patina over time. Protected by a scratch-resistant sapphire crystal, the watch is powered by the reliable Omega Caliber 1120 automatic movement, renowned for its precision and durability. Water-resistant to 300 meters when properly serviced, it combines professional diving performance with versatile everyday wearability. A timeless vintage Seamaster, highly appreciated by collectors for its classic proportions and beautifully aged tritium dial.
