Named after the Greek word for sea, the Pelagos is Tudor's high-tech dive watch. It features a titanium case with a ceramic bezel insert and a stainless steel case back, able to withstand depths up to 500 meters. Inside is Tudor's own caliber MT5612. The Pelagos is fitted with a titanium bracelet with a steel folding clasp that has a unique auto-adjustable spring mechanism developed and patented by Tudor. A rubber strap (including an extension piece) is also included. Last but not least, it also features a helium escape valve - a feature much appreciated by saturation divers.

The Tudor Pelagos M25600TB-0001 has a blue dial and matching bezel insert.
