Omega Seamaster 120M | Uncommon Blue 12-6-9 Arabic Dial | Ref. 2511.83

The Omega Seamaster 120M Ref. 2511.83 is an uncommon neo-vintage Seamaster distinguished by its blue dial with oversized Arabic numerals at 12, 9, and 6 o’clock. Housed in an approximately 36mm stainless steel case, the watch features a smooth polished bezel, sapphire crystal, stainless steel bracelet, screw-down crown, and date display at 3 o’clock.

The standout feature of this reference is its unusual dial configuration. The deep blue dial combines large luminous Arabic numerals with applied baton hour markers, luminous hands, and a framed date window. This gives the watch a sportier and more distinctive appearance than the standard Seamaster 120M dial while retaining a compact and versatile profile.

This particular example displays visible staining and discoloration on both the dial and hands. Yellow-brown staining can be seen around portions of the hour markers, while the luminous material within the hands also shows age-related discoloration. These characteristics are visible in the provided photographs and give the watch an honest neo-vintage appearance.

Powered by Omega’s quartz Calibre 1538, the watch offers precise timekeeping, a date function, and an end-of-battery-life indicator. The model was originally rated to 120 meters of water resistance, although water resistance is not guaranteed due to its age.

Condition

Please review the photos carefully for an accurate representation. The blue dial and hands display visible staining and age-related discoloration. Additional scratches, bracelet wear, bezel wear, crystal wear, or other signs of use consistent with age may also be present.

The staining is cosmetic and has been disclosed for complete transparency. Please examine the photographs closely to assess the dial, hands, hour markers, case, bracelet, and overall condition.
