Vintage Omega Seamaster De Ville Automatic Tropical Dial 166.020 - 34,5mm - 1967

A vintage Omega Seamaster De Ville produced in 1967, featuring an incredibly well developed tropical dial. Originally finished in a sunburst white tone, the dial has aged into a beautifully even, light orange patina distributed across the entire surface, a specific character only vintage watches have developed.

The stainless steel case measures 34.5 millimeters in width and remains in beautiful condition. Inside beats the caliber 565 automatic movement, serviced in February 2026 and currently running and functioning excellently, featuring the convenient quickset date function typical for this caliber.

We have paired this watch with a black grade 3 leather strap with a crocodile motif and a subtle glossy finish, which complements the warm tones of the tropical dial beautifully. Overall, the watch remains entirely original, except for the brand new strap, and stands in beautiful condition with a truly unique tropical dial, making it a distinctive and characterful vintage piece.
