The OMEGA Seamaster 120M Chronometer 2501.81.00 offers a refined interpretation of the iconic Seamaster collection, combining elegant proportions with dependable Swiss engineering. Introduced during the 1990s, this reference bridges the gap between a dress watch and a sports watch, making it one of the most versatile vintage-modern Seamaster's available.
Its striking blue wave-pattern dial is complemented by a polished stainless-steel bezel, luminous hands and hour markers, and a beautifully proportioned 36.25mm stainless steel case. The result is a timeless design that wears comfortably on a wide range of wrist sizes while retaining unmistakable OMEGA character.
Powering the watch is the renowned OMEGA Calibre 1120 automatic chronometer movement, a COSC-certified calibre celebrated for its accuracy, reliability, and smooth operation. Offering approximately 44 hours of power reserve, it remains one of OMEGA's most respected automatic movements from the era.
