Omega Constellation Ref.168.046 Cal.1001 36.0mm 1970

The Constellation Ref.168.046 presents a sculpted tonneau silhouette whose broad shoulders flow into an integrated attachment design. Its proportions bring a sense of architectural order to the wrist, while the date display adds a practical note to the composed dial layout. The automatic Cal.1001 gives this expressive vintage design the mechanical substance associated with Omega’s chronometer collection.

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.1001 inside running excellently as shown in the timegrapher reading above, just like it was when it left the factory nearly half a century ago.
