Dear watch aficionado.
Here a nice and rare example of a Longines Calatrava from 1938 in a 38mm 14kt yellow gold case and black épargne dial:
This example has a lovely and rarely seen black épargne dial made by Lemmerich. These dials were very complicated to be made and do add tremendous value. The examination of the dial shows that it is all original and correctly stamped on the back with the correct signs of how this dial was made back in the day.
I invite you as well to take a look at my site www.watchcollector.lu for the current offer of vintage and independent timepieces.
