Condition:

The watch remains in honest antique condition. The 0.800 silver case shows normal age-related wear, surface marks, oxidation and wear around the edges. The engine-turned decoration on the back remains clearly visible, although some areas show smoothing from long-term use.

The distinctive 24-hour enamel dial remains highly legible, with its black and red numerals, cardinal-direction markings and subsidiary seconds display retaining strong visual presence. Several areas of enamel loss and old repair are visible around the outer part of the dial, particularly near approximately 12, 4 and 8 o’clock. These areas are clearly shown in the photographs. Despite these age-related defects, the principal numerals, Omega signature, directional markings and subsidiary seconds dial remain clearly readable.

The movement appears visually complete and shows normal age-related surface and use marks.
