Matte black, signed Ω, OMEGA, AUTOMATIC, Seamaster 300, with tritium luminescent indices, ‘Big Triangle’ at 12 o’clock, Arabic hour numerals at 3, 6 and 9.
Presented in very good pre-owned condition, the dial has an attractive patina, with the tritium markers taking on a pleasing, age-related, hue, the original handset has near-matching colouring, but the hour hand may have been re-lumed in the past. The asymmetric case is strong, retains thickness, and has expected user-related wear. The bezel is original and in remarkably good condition given the age and adds to overall eye-catching appearance of this desirable reference.
