Model number CAH1111.BA0850 authentic TAG Heuer Formula 1 chronograph. I haven't worn this watch much. I had to have the movement replaced due to leaving a bad battery in it and the place that repaired it put it back together so that the date turns at 7 o'clock instead of 12 o'clock. Not really a big deal and could be fixed rather cheaply but I don't want to spend anymore money on it. The watch is in excellent condition and has been worn very little. Comes with the original box, owners manual and band links that were removed to fit my wrist. $400 obo ftf in Puyallup/Tacoma area. Will ship at buyers expense. Will trade for stripped or complete AR15 lowers.
