Omega Seamaster Jumbo Ref.166.067 Cal.565 36.0mm 1969

This beautifully preserved Omega Seamaster Ref.166.067, comes housed in the same true jumbo-sized 36.0mm stainless steel case with rare fat lugs, a sparkle dial, and a crisp no-bezel construction. A distinctive, oversized piece that captures both rarity and elegance in vintage Swiss watchmaking.

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.
