Longines Conquest Ref.8066 Cal.501 35.0mm 1967

A sharp and refined example of the late-60s Longines Conquest with a clean and timeless silver satin dial, housed in a well-proportioned 35.0mm case. This Reference 8066 from 1967 is powered by the reliable and smooth Caliber 501 movement, offering a practical date complication and dependable automatic performance. Not to mention the stunning grooved indexes across the dial that reflect the light brilliantly.

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