Blancpain Fifty Fathoms MIL-SPEC 5008-1130-NABA

About This Watch

The Blancpain Fifty Fathoms MIL-SPEC is a modern tribute to the military specification Fifty Fathoms watches supplied to various navies during the Cold War. The MIL-SPEC designation references the moisture indicator at 6 o'clock — a small disc that changes color if water enters the case, a feature originally required by military specifications for dive watches. At 40mm, the MIL-SPEC is the most compact Fifty Fathoms, making it exceptionally wearable compared to the standard 45mm model while sacrificing nothing in terms of mechanical content. The same caliber 1315 with 120-hour power reserve and silicon hairspring provides the movement foundation. The military-inspired aesthetic, with its matte finishing and NATO-style strap, gives this model a purposeful, tool-watch character that distinguishes it from the more polished standard Fifty Fathoms. The compact dimensions and vintage-inspired design have made the MIL-SPEC particularly popular among collectors, with secondary market prices consistently above retail. For those who appreciate the heritage of military dive watches, the MIL-SPEC is the most authentic modern Blancpain.
