Omega Seamaster Ref.166.009 Cal.562 34.0mm 1966

Up for grabs would be the vintage Omega Seamaster 166.009. Blending form and function with its Caliber 562 automatic movement and refined 34.0mm stainless steel case. With a briliant mix of late 50s classic design and an original rare scallop crown. Ideal for those who appreciate heritage watches that are both wearable and collector’s pieces. Not to mention the Onyx stone inserts perfectly placed on every hour marker.

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.
