About the Pelagos family
The Pelagos was introduced in 2012 as Tudor's professional dive watch, with a titanium case and bracelet, a helium escape valve, a ceramic bezel and 500 metres of water resistance. Its bracelet clasp has a spring that adjusts to the expansion of a wetsuit.
The model moved to the in-house MT5612 in 2015. The family also includes the left-hand drive LHD, the 39 mm Pelagos 39, and the Pelagos FXD of 2021, developed with the French Navy, with fixed bars between the lugs and models in carbon composite.
