Authenticity Guaranteed
Every timepiece is carefully inspected, independently authenticated, and accurately represented before it reaches your collection.

Blancpain
The Nageurs de Combat honors the French Navy combat swimmers who were among the first to test the original 1953 Fifty Fathoms — the only modern Fifty Fathoms with a closed caseback, engraved with the unit's anchor-and-seahorse badge. Limited to 300 pieces, with the symbolic '7' on the dial for the seven-meter oxygen-diving limit. Military provenance doesn't get more direct than this.
