The Pelagos, meanwhile, comes with a titanium construction. In fact, it’s the first titanium diver within the Rolex brand. With a 42mm case, it’s larger than the Black Bay and even the traditional Submariner, but its lightweight material provides comfortable wear. In keeping with the contemporary look, the Pelagos is equipped with a ceramic bezel with luminous markers.
While you can also dive with the Black Bay, the Pelagos was certainly created for this purpose. Compared to the Black Bay’s 200m depth rating, the Pelagos has 500m depth capability, so Tudor added a helium escape valve on the side of the case to enable saturation diving. It also comes with a diver’s extension rubber strap to use over a wetsuit.
