Developed to unique specifications, the Pelagos FXD models are designed and optimized for professional diving and competitive yacht racing. FXD refers to the extra robust fixed strap bars of the case. The new Pelagos FXD pays tribute to decades of TUDOR watches on the wrists of Navy divers. Complete with fixed strap bars, a titanium case, a high-performance Manufacture Calibre and a unidirectional elapsed-time rotating bezel, it comes as the ultimate modern military diving watch.
