In the late 1990’s Universal Geneve teamed up with the Ayrton Senna Institute (IAS) and created a series of watches from which part of the profit was donated to the IAS. The watch listed here is the chronograph model ‘Senna 41’. All (but one) versions were made in steel in combination with something what Universal Geneve mentioned as carbon at that time. To my knowledge it wasn’t true carbon, but merely a kind of plastic, probably blended with some carbon enabling to use ‘carbon’ in it’s description. Fun fact: Donald Trump used to own a personalized 18k version that he later donated to be auctioned off. The watch is 41mm and I believe the movement  Valjoux 7750, or at least that is what other listings for the same watch state.
