Hublot teams with Brazilian racer Bruno Senna, nephew of the late racing legend Ayrton Senna, to produce a special model for the Swiss watchmaker’s “Masterpiece” collection. The MP-06 Senna is the fourth such collaboration between Hublot and the Senna family, and features a tonneau case with a see-through dial that shows the hand-wound tourbillon caliber, which includes a 5-day power reserve. A nod to the racing inspirations of the collaboration, the watchband is made of perforated Schedoni leather reminiscent of Ferrari and comes backed with green, red, or yellow (seen here) to match the hands and dial depending on the version selected. A release rich in symbolism, the special-edition MP-06 Senna commemorates Ayrton’s 41 victories and three championship titles, and is available in King Gold, Titanium and black PVD titanium case options. Each model will be limited to only forty-one units per case and will comes in a special Hublot presentation case accompanied by a miniature reproduction of Ayrton Senna’s helmet.
