The Fifty Fathoms 70th Anniversary Act 3 is a striking tribute to one of Blancpain’s most historically significant dive watches. Inspired by the original MIL-SPEC model issued to military forces in the 1950s, this limited edition reimagines the past with modern craftsmanship and enduring materials. Only 555 pieces were produced, each evoking the legacy of underwater exploration with purpose and precision. At the heart of this 41.3 mm timepiece is a case forged from Blancpain’s proprietary 9K Bronze Gold—a warm-toned alloy that blends gold, copper, silver, palladium, and gallium to create a vintage aesthetic with contemporary resistance to oxidation and skin reaction. The black Dial features a functional moisture indicator, just like the original military version, alongside a satin-brushed unidirectional bezel with a black ceramic insert and vintage-colored Super-LumiNova® markers for legibility in low light and deep water. With 300 meters of water resistance, it’s built for the challenges of professional diving. Inside beats the Caliber 1154.P2, an automatic movement that offers a 100-hour power reserve and resistance to magnetic fields up to 1,000 Gauss, thanks to its silicon balance spring and non-ferrous components. The sapphire case back reveals the beautifully finished movement, a reminder of Blancpain’s mechanical artistry. Completing the look is a black NATO strap made from recycled fishing nets, emphasizing the brand’s commitment to sustainable ocean stewardship. This is not just a dive watch—it’s a chapter in diving history, reborn.
