Blancpain presents the third act marking the 70th anniversary year of its iconic Fifty Fathoms diver's watch. Named "Fifty Fathoms 70th Anniversary Act 3", this model is inspired by the MIL-SPEC model adopted by the main armed forces of the time.

The Manufacture is now offering a 555-piece limited-edition reinterpretation of the timepiece with its trademark moisture indicator. Faithful to its original 41.30 mm diameter, the Fifty Fathoms 70th Anniversary Act 3 is made of 9K Bronze Gold.

This third anniversary timepiece is indeed inspired by its non-magnetic parent used by the US Navy. The matt black dial with vintage Super-LumiNova®-enhanced moisture indicator and hour-markers; the unidirectional rotating bezel with black ceramic insert featuring a vintage Super-LumiNova® diving scale; as well as the two-tone NATO strap featuring the colour code of the original timepiece and made from fishing nets recovered from the oceans are all features that demonstrate their close kinship. They are however distinguished from each other by the material used for the case.

While the MIL-SPEC from which the anniversary model is inspired is made of German silver, the Fifty Fathoms 70th Anniversary Act 3 is clothed in 9K Bronze Gold, a patented alloy enriched with 37.5% gold (hallmarked 9K), copper – 50%, allowing it to be called "bronze" – silver, palladium and gallium.
