Blancpain Fifty Fathoms 3H BundeswehrThis is a rare and fascinating Blancpain Fifty Fathoms, crafted for the German Bundeswehr frogmen in the 1970s. These watches were not available for public sale but were exclusively issued! You'll notice that this watch departs from the typical Blancpain Fifty Fathoms appearance due to its unique bezel insert. Since the Bund divers used rebreathers and didn't require the graduated dive bezels seen on Rolex Subs, the insert is plain and numeral free.
