Omega Constellation Ref.167.015 Cal.551 34.0mm 1968

The Constellation Ref.167.015 expresses late-sixties elegance through a beautifully restrained silhouette and a dial devoted entirely to the time. Its compact monocoque architecture lends the watch a seamless presence, allowing the proportions to speak with quiet confidence. Inside, Omega’s Cal.551 brings the collection’s chronometer heritage to a piece made for the pleasure of understated dressing.

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