Omega Constellation Ref.168.041 Cal.751 40.0mm 1969

This beautifully preserved Omega Constellation Ref.168.041 is housed in its distinctive 40.0mm stainless steel tonneau shaped case, a design famously associated with the golden era of Omega chronometers. The case flows seamlessly around the wrist, complemented by applied indices with matching tritium plots and an original Omega-signed crown, all coming together in a cohesive and unmistakably vintage aesthetic. Not to mention a stunning 14k white gold coin edge bezel that shines brilliantly in the light.

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 chronometer-rated Cal.751 movement inside running excellently as shown in the timegrapher reading above, just like it was when it left the factory over half a century ago.
