Overview
The Tudor Pelagos FXD Chrono Alinghi Red Bull Racing (ref. 25807KN) is a purpose-built sports chronograph that unites Tudor's dive-oriented Pelagos architecture with the high-performance demands of competitive offshore sailing. Its 43 mm carbon composite case and blue carbon dial reflect the materials language of the Alinghi Red Bull Racing sailing team, with whom Tudor holds an official partnership. Powering the watch is the in-house Calibre MT5813, a column-wheel chronograph movement that underscores Tudor's commitment to manufacture-level horology.
History
The Pelagos line was introduced by Tudor in the early 2010s as a professional-grade diver aimed squarely at tool-watch enthusiasts, distinguished from the outset by its titanium construction and in-house movements. The FXD sub-family extended that ethos by adopting a fixed-strap-lug system originally conceived for military and diving applications, eliminating the risk of strap detachment under extreme conditions. The Alinghi Red Bull Racing edition, launched in 2023, deepened Tudor's long-standing involvement in elite sailing and brought chronograph functionality to the FXD platform for the first time. The collaboration reflects a broader strategy of aligning Tudor's technical identity with the engineering culture of world-class competitive sport.
Notable points
