When Bell & Ross and Alpine join forces, it’s as much a meeting of values as a testament of technical partnership. What brings the two entities together is the same passion for precision mechanics and high performance. Echoing this quest for efficiency, Bell & Ross has equipped its BR 05 Chrono A523 with a resilient movement, the selfwinding mechanical BR-CAL.326 calibre with hours, minutes, small seconds at 9 o’clock and date functions.

Decorated with the French flag, complete with the team blue and displaying the Alpine logo as a counterweight to the chronograph hand, the finely graduated black dial with two counters focuses on readability and functionality under all circumstances. This rise in power is granted by the talents of drivers Pierre Gasly and Esteban Ocon, who both now wear a BR 05 Chrono, each engraved with their name and number.
