Well quality Heuer Carrera CV2A11.FC6235 watches

The original owner died of emphysema. Heuer made the Viceroy 1163 back in the 70's - once you had enough coupons off their cigarette cartons you could buy the watch really cheap. Well quality watches sort of cheap - what you didn't need in dollars was paid for with years off your life.

CV2A11.FC6235:

 I have a Dremel tool but have been too scared to use it on any Tag Heuer Carrera watches (sticking to manual methods) as I worry about burning, overpolishing or even scratching the cases worse that when I started...
Wondering if you have a preferred speed setting or just stick to the slowes
