November 3, 2014, would have been Ayrton Senna’s 54th birthday. On that date in 2010, on the occasion of the Interlagos Grand Prix in Brazil, Senna’s sister Viviane, along with the Instituto Ayrton Senna and Hublot, united the Formula 1 family along with Senna’s friends and loved ones to commemorate his 50th birthday, which featured the premiere of the award-winning documentary film Senna as well as the debut of this timepiece, created by Hublot in support of Instituto Ayrton Senna.
The Hublot King Power Ayrton Senna is a split-second chronograph with power reserve indicator limited to 500 numbered pieces, stamped with Ayrton Senna’s signature. It is made entirely from materials used in Formula 1. In a first for Hublot, the case is made from carbon fiber, a material widely used in Formula 1. The bezel is ceramic with a circular-grained satin finish adorned with multiple holes to represent an F1 brake disk which is also made from ceramic. The strap is Nomex, a synthetic fiber developed by Dupont and used to make the suits worn by F1 drivers. The power reserve indicator at 6 o’clock in green, blue and red evokes the timers used in Formula 1. Finally, the sapphire caseback features a laser-engraved portrait of Ayrton Senna with yellow infill for the engraved text. The watch comes in a special Hublot presentation case, made from black ebony with a sapphire glass window decorated with a transfer of Ayrton Senna’s signature in yellow, matching the one on the sapphire crystal of the watch’s dial. The King Power Tourbillon Ayrton Senna is an edition of 10 exceptional tourbillons manufactured entirely by Hublot, each with a different commemorative engraving on the caseback showing one of 10 highlights in the driver’s career, as chosen by his sister and mother. Additional technical information for the Tourbillon appears below the images, which may be enlarged with a click.
