Since the 1950s and TUDOR's creation of one of the first modern professional divers' watches to the 1980s, the brand has been an official supplier to the Marine nationale (French Navy). With the Pelagos FXD model, where FXD refers to the extra robust fixed strap bars of the case, TUDOR is reviving this historic collaboration.
