Vintage Omega Art Deco Tank, Rare Chocolate Patinated Copper Dial, Cal. T17

Vintage Omega watches from the 1930s often blended elegance with mechanical innovation — and this rectangular Tank model powered by the legendary Cal. T17 delivers both with striking character.
This example features a richly patinated copper dial that plays beautifully in the light, shifting from deep chocolate brown to a lighter copper hue depending on the angle. Framed by a classic stepped rectangular case, the dial is accented with blued sword hands and Roman numerals, completing its refined 1930s aesthetic. Inside, the in-house T17 movement reflects Omega’s early commitment to slim yet robust calibers.
