It's an interesting topic 'Pilot watches', is it not true that the wrist watch was invented for Pilots, therefore all wrist watches by definition are 'Pilot watches?'
I can't remember which pioneering Pilot it was, I seem to recall the name 'Cartier' who made a wrist watch for 'Santos Dumont', he could not take his pocket watch out to check the time because he required both hands to control his machine? Thus Cartier invented the wrist watch, although several different names seem to claim the same invention!
Then again, I'm probably talking ball@cks
