Tudor was founded in Geneva in 1926 as a sister brand to Rolex, created to offer Swiss-made tool watches at a more accessible price point. Over the decades the brand has built a strong independent identity — particularly in the Pelagos line, which was developed in close collaboration with the French Navy Marine Nationale and carries genuine professional dive watch credentials. The Pelagos FXD, introduced in 2021, adds a distinctive engineering detail to that formula: fixed titanium lug bars that eliminate bracelet play entirely, reducing movement on the wrist under demanding conditions. The 25707KN is the Alinghi Red Bull Racing edition, developed in partnership with the Swiss-New Zealand America's Cup sailing team.

Reference 25707KN is a 42 mm carbon composite automatic watch, 12.8 mm in thickness, with a matte finish and the Alinghi Red Bull Racing logo engraved on the caseback. The blue dial carries Tudor's signature snowflake hands and square hour markers in LumiBrite, with a red seconds hand adding a clear motorsport reference. At its heart beats the Tudor Manufacture Calibre MT5602, COSC-certified, running at 28,800 vph with a 70-hour power reserve. The domed sapphire crystal sits above. The bidirectional rotating bezel features a carbon composite insert with a full 60-minute countdown scale for regatta timing. Water resistance is rated to 200 metres. The watch is presented on a navy blue fabric strap with red accents and a titanium D-buckle.

This Tudor Pelagos FXD Alinghi Red Bull Racing is in near mint condition and comes as a full set.
