Before my eyes got too bad and my hands got too shaky, my "other" hobby was watchmaking. I have all the gear (and probably no idea) and haven't seen a car related watch that has impressed me yet! Most of them are very simple movements, purely marketing exercises.
Some of the Formula One watches are OK'ish but if you want a proper watch, get a genuine Breitling, Omega or Roly Poly but ............................ do not get taken in by the very good fakes! If you think that Rover cars have officionados, just get onto some of the watch forums. Phew!
My favourite watch is one I built myself, using all swiss parts. Apologies for the rubbish camera pic!
Swiss ETA 7750 movement. An engineers dream!
