I had seen that before ... I think in the GD forum
He defo wears the Hamiliton Khaki king and a Zeno before that and I think originally it was a Casio of some kind... but cant remember exactly..
Funny enough i saw an interview with him a Stephen Fry.... Originally he was in a comdey duo called Fry and Laurie and they were doing a catch up show... initially I thought he was wearing a Uboat but not so sure now though...
Funny how different House is from all he had done previously..... Blackadder, Jeeves and Wooster, Young Ones, A bit of Fry and Laurie etc
