Hublot Big Bang Foudroyante Senna Limited Edition

Hublot Big Bang Foudroyante Senna Limited Edition, the second Big Bang with the motor-racing champion’s signature, was launched in Japan. Within the framework of an exhibition of previously unpublished photos featuring Ayrton Senna, taken by his photographer friend Norio Koike, Hublot confirmed its support for the Instituto Ayrton Senna, founded by Viviane Senna, the sister of the late racing driver. During this event, Jean-Claude Biver presented to the media and the public the second version of the watch, called “Big Bang Senna Foudroyante” .

Hublot is also honoured by the presence in Tokyo of its ambassador, Bruno Senna, Viviane’s son, a talented young motor-racing driver, who has already made a name for himself on the circuit when he achieved second place in the GP2 championship this season. Whereas the first Big Bang had been launched during the F1 Grand Prix in Sao Paulo in 2007. This year, Hublot and the Instituto Ayrton Senna chose to unveil another side of Ayrton’s life never previously seen. The doors are open to an exhibition of photographs of Ayrton taken in his private and public life, by a close friend of his, the Japanese photographer Norio Koike.

Norio Koike met Ayrton Senna in 1988, and very quickly won his trust. A relationship of friendship and complicity enabled him to take photos of the champion at different times, and often at just the right moment. A sincerity and genuine intimacy radiate from these pictures which, until today, had remained unpublished. After Ayrton Senna’s death, Norio Koike bequeathed the photos to the Instituto Ayrton Senna.

The Instituto Ayrton Senna, a non-profit organisation, was founded to honour Senna’s ideals: his dream was to bring more dignity and equity to his country. It is dedicated to the education of children, at school as well as in society, to enable them to develop their capacities to the full. Since its foundation, 14 years ago, by Viviane Senna, 9.4 million children have benefited from its programs in 25 Brazilian states. Over 85 million US dollars have been invested to enable it to pursue its educational objectives.

The Big Bang Foudroyante Senna, a 500-piece numbered limited series, sports the colours of Brazil, like the first edition: yellow and green split-seconds hand, yellow minute markers, Brazilian flag on the case-side element, Ayrton Senna’s signature in green on a matt black dial.

Its split-seconds chronograph movement features a new complication, the Foudroyante, which enables the calculation of one-eighth of a second. The serial numbers on the back are engraved in yellow ink on black ceramic, and the logo “Instituto Ayrton Senna” appears as a transfer on the sapphire crystal.
