Blancpain Fifty Fathoms MIL SPEC Hodinkee SS Black Dial LIMITED

This Blancpain 5008-11B30-NABA — the Fifty Fathoms MIL-SPEC produced with Hodinkee in a limited run of 250 — is a faithful modern reprise of the dive watch that once satisfied the US Navy's most exacting underwater requirements, a piece for the collector who prizes tool-watch authenticity over ornament. It is driven by an automatic movement fitted with a silicon balance spring and a four-day power reserve, visible through the caseback by way of a solid-gold rotor finished in grey NAC and engraved with both partners' names. The brushed stainless steel case measures 40.3mm across with a thickness of 13.2mm, its unidirectional sapphire-insert bezel and screw-down crown built for genuine descent rather than the appearance of it. The dial is matte black, distinguished above 6 o'clock by the two-tone white-and-orange moisture indicator — the functional signature that defined the original military MIL-SPEC and shifts colour should water breach the case. A working piece of dive-watch history, reissued with quiet fidelity, it ranks among the most collectable of Blancpain's modern Fifty Fathoms.
