36mm Blue Dial | Automatic | Ref. 2501.81

The Omega Seamaster 120M Ref. 2501.81 is a clean and understated neo-vintage Seamaster that combines the sporting character of the collection with more refined everyday proportions. Featuring an approximately 36mm stainless-steel case, smooth steel bezel, and matching stainless-steel bracelet, the watch offers a compact and versatile alternative to Omega’s larger Professional dive watches of the same era.

The blue dial is the defining feature of this configuration, featuring applied hour markers, luminous hands, center seconds, and a practical date window positioned at 3 o’clock. A scratch-resistant sapphire crystal protects the dial, while the relatively slim case profile gives the watch a comfortable and refined presence on the wrist. Documented examples measure approximately 36mm in diameter, around 10mm thick, and use an 18mm lug width.

Condition

Please review the photos carefully for an accurate representation. Light scratches, bracelet wear, bezel wear, crystal wear, dial aging, or other signs of use consistent with age may be present and do not affect functionality. The watch presents well overall with expected wear for its age.
