Motorcyclist Lorenzo Joins Tissot Team of Ambassadors
Jorge Lorenzo, who has won the MotoGP World Championship three times, has joined the Tissot family of celebrity ambassadors.

Le Locle, Switzerland--Champion motorcyclist Jorge Lorenzo, who has won the MotoGP World Championship three times, has joined the Tissot family of celebrity ambassadors, the brand announced.
Lorenzo has been in the public eye since the age of 8, when he won the Balearic Championship.
In 2002, on his 15th birthday, he became the youngest rider in the World Championship. Since then, he has won three World Championships (2010, 2012 and 2015), has been runner-up three times (2009, 2011 and 2013) and has achieved a record number of Poles (62).
“We are very pleased to welcome Jorge Lorenzo to the Tissot family,” brand President François Thiébaud said. “His passion, courage and fighting spirit fit with the values of Tissot perfectly.”
Tissot is the official timekeeper for MotoGP and has a number of other motorcycle riders already in its stable of brand ambassadors, Stefan Bradl, Thomas Lüthi, Tito Rabat and Bradley Smith.
“It is an honour for me that Tissot, such a prestigious brand with so much history in motorcycling, entrusts me with the role of ambassador,” Lorenzo said. “Tissot plays crucial role in the races and sets the pace in MotoGP. Now, I would like to return the favor and trust with victories and maximum precision on the track.”
