Vintage Omega Genève Tropical Purple Dial Japanese Market model 166.721 - 37,5mm - 1970

This vintage 1970 Omega Genève was made exclusively for the Japanese market and has developed a unique, incredible, purple tropical patina over time. It is powered by the Caliber 565 automatic movement, overhauled in November 2025 for great functionality.

The watch remains entirely original except for its newly replaced black calf leather strap, which fits wrists up to 20cm. An uncommon piece made unique due to the dial development.
