Technical Description
The Act 3 features a 41.3 mm case crafted from Blancpain’s patented 9K Bronze Gold alloy, combining the warm hue of bronze with the stability of gold, paired with a unidirectional Bronze Gold bezel and black ceramic insert. It offers 300 m of water resistance, straight lugs that echo the original 1950s Fifty Fathoms, and a sapphire display back that showcases the automatic calibre 1154.P2 with 100 hours of power reserve and anti‑magnetic silicon balance spring.




The matte black dial carries vintage‑effect Super‑LumiNova markers and hands plus the signature moisture indicator at 6 o’clock, a direct reference to historic military‑issued Fifty Fathoms pieces. A black and gold two‑tone NATO strap, made from recycled fishing nets and fitted with a Bronze Gold pin buckle, completes the dive‑ready yet refined presence on the wrist.
