“In 1953, Captain Robert Maloubier of the French Navy's combat swimmers needed a reliable dive watch. He approached Blancpain CEO Jean-Jacques Fiechter and together they created the Fifty Fathoms — the original modern dive watch. The cal. 1315 delivers an extraordinary five days of power reserve from three series-coupled barrels.

“On paper, 41mm with 13.1mm thickness sounds chunky for a dress chronograph. In practice, the case is superbly sculpted. The downturned lugs hug a 17cm wrist beautifully, and the slim bezel makes the dial feel expansive. Lange understands ergonomics far better than the spec sheet suggests.”

“Having examined this reference under a loupe, the level of hand-finishing on the movement is extraordinary. The three-quarter plate features impeccable Glashutte ribbing, and the hand-engraved balance cock is a work of art unto itself. The column-wheel chronograph operates with a tactile precision that puts most Swiss competitors to shame.”
