Tudor Pelagos 39 Reference M25407N-0001

Partially verified

The Tudor Pelagos 39 is a diving wristwatch housed in a 39mm titanium case. It is fitted with a unidirectional 60-click bezel and a signed screw-down crown, offering a water resistance rating of 200 meters. The timepiece features a black dial with applied hour indices and the characteristic ‘snowflake’ handset. Text on the dial includes the Tudor logo, the ‘Pelagos’ signature in red, and certification markings. It is powered by the Tudor Calibre MT5400 movement, which holds COSC certification and provides a 70-hour power reserve. The watch is completed by a titanium bracelet equipped with a proprietary ‘T-Fit’ clasp. This model serves as a iteration within the Pelagos product line, focusing on dimensions and simplified design elements compared to other contemporary divers from the same manufacturer.
