Description from the seller

Omega Military-Style WWII Era – Tropical Bullseye Dial – Cal. 26.5 SOB – Circa 1939

This vintage Omega pairs a 31 mm Staybrite case with a striking tropical bullseye dial. The silvered centre has developed a mottled honey-brown patina, set against a dark hour ring with bold Arabic numerals. A finely grooved small-seconds register at 6 o’clock completes the layout, while the Swiss Omega Cal. 26.5 SOB gives the watch its mechanical character.

Condition Report

Grade B, with visible signs of age and use. The dial shows pronounced spotting and discolouration, particularly across the silvered centre, with visible ageing to the numerals and hands. The case and case back show surface scratches and small marks. Please refer to the photographs for details. Water resistance has not been tested.

Story & Heritage

The military-style design comes through in the way the dial reads: large numerals sit on a dark ring, giving the hours a clear place of their own, while the small-seconds register keeps the centre uncluttered. The bullseye layout still has that strong visual structure today, even as the silvered centre has taken on a warm, speckled patina. It’s the contrast between the disciplined layout and the irregular ageing that gives this Omega its character.
