Tiger Woods watch at the Deutsche Bank Championship?

Hi everybody, I'm crazy abou****ches and ... in particular all the luxury European brands ... as Patek, Rolex, TAG Heuer , Breitling ... I've seen Tiger Woods playing during the Deutsche Bank Championship that was taking place in Boston. He wore a watch I've never seen before. This watch was quite original. The clap caught my attention. It was not placed, as usual, on the inside of the wrist. Maybe, you had the chance to see this competition on Espn or Cnn and you could help me to figure out what brand it is. And which model? Thanks for your help. John
