Omega Geneve Shibui Ref.166.721 37.5mm Cal.565 1969

The Omega Genève Shibui Ref. 166.721 is one of the most distinctive Genève references produced, originally created as a Japan-market variant during the late 1960s. Housed in a bold 37.5mm UFO-shaped stainless steel case, it perfectly captures the futuristic design language of the era while remaining surprisingly wearable today. This example is especially attractive with its original silver sunburst dial, faceted black-inlaid indices, and rare Omega Milanese mesh bracelet, giving it a uniquely refined yet sporty presence on the wrist. Beneath the striking exterior beats Omega’s highly regarded Cal.565 automatic movement, a robust and collector-favourite calibre renowned for its reliability and stunning finishing.

In addition, this timepiece comes freshly serviced with all parts laid out by our professional watchmaker for all to see in the images above. Little to no other dealers do this and it’s a testament to full transparency here at Montre D’or. With the Cal.565 inside running excellently as shown in the timegrapher reading above, just like it was when it left the factory nearly half a century ago.
