Vintage Omega Bumper Automatic Small seconds Arabic Numerals 2398-2 - 35mm - 1950

For sale is this vintage Omega bumper automatic from 1950. It features a white dial with speckles of patina, golden hour markers, Arabic numerals, Dauphine hands, and a “small seconds” sub dial above six o’clock. Inside is a freshly serviced caliber 332 bumper automatic movement, serviced in October 2025 and running excellently.

The case stands out with its 18-micron gold plating—four times thicker than the usual Omega plating—most likely made by an American case manufacturer to reduce costs in the USA. This makes the piece uncommon and increasingly rare. Condition is very good, and we’ve paired it with a black Hirsch calf leather strap that fits both small and larger wrists. A unique vintage Omega and a superb dress watch.
