Waterproof to 500 m (1,640 ft), the Pelagos is fitted with a movement manufactured in-house by TUDOR. It is now available in a new “left-handed” version, designed to be worn on the right wrist. The dial has been reworked with beige luminescent markings and the name PELAGOS in red at 6 o'clock. Tudor first produced watches of this type at the specific request of diving professionals, including the French Navy during the 1970s.
