## Caption

The Longines calibre 30CH was introduced in 1947, as an upgrade of the 13ZN (1937-1947) until the early 1970's. Pieces powered by the Cal. 30CH are the most sought-after watches ever produced by Longines.
 
This Reference 6075-4 has a large 37.5mm case diameter with the famous "doppio linguetta", referring to the shape of the high-pressure snap-on back with a large lip that looks like two little ears. The two-part case has matching numbers, one is present underneath the upper left lug and the other one in the inside caseback.
 
This piece further has a silvered luminescent "telephone" dial. Over the time and thanks to the radioactive material used, it has acquired a most attractive, charming and natural patina. It gives even further character to this charismatic piece.
 
A highlight of the ‘Fine Watches’ sale at Sotheby’s Paris, view the full catalogue and bid online at the link in bio.
