Longines Calatrava Enamel Dial Ref.3029-1 Cal.L631.1 35.0mm 1975

One of Longines most understated timepieces, a huge value for money piece coming with an enamel Roman dial normally found in high horology pieces. That would be the Longines “Calatrava” Ref.3029-1, in this case with a brilliant original Longines Milanese mesh bracelet as well. Making the perfect elegant dress watch for the fanciest of occasions at an attainable price point.

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.L631.1 inside running excellently as shown in the timegrapher reading above, just like it was when it left the factory nearly half a century ago.
