  • Fifty Fathoms - a passion for the underwater world
  • Presented in a 38mm polished steel case secured with a blue sail-canvas strap
  • Powered by the 1150 automatic movement
  • Equipped with an impressive 100-hour power reserve
  • Offers water resistance to 30 bar (300 metres)


This spirited collection embodies Blancpain’s passion for the underwater world, originating from the presentation of the first modern diver’s watch in 1953.

Today, the collection retains the core signature elements that established the legendary model as the archetypal diver’s watch, updated with innovative materials and new technical solutions to push boundaries and meet even the most sophisticated diving needs.


This deep blue Bathyscaphe model sits confidently in a 38mm steel case, with a unidirectional, satin-brushed steel bezel with a ceramic insert.

Uniting enhanced legibility with a truly sophisticated aesthetic, the brushed blue dial features white luminescent hands and hour markers, and a date display.

Offering an additional nod to the timepiece’s rich ocean heritage, a blue sail-canvas strap completes the look, while power and precision are provided by the 1150 automatic movement.
