I go behind a Monaco ref. 73633B, what do you think would be the fairest price to pay for that model? always considering that it is 100% original.

 

have you checked Heuer Price Guide? A good reference for me. Prices seem low sometimes but they are researched. Between collectors these prices should be possible.

 

thanks, I just read it, in a medium range I would have to look for $ 5,000,

 

Yes but that might be very hard to find
Medium range means all original, traces of use but no polishing. Perhaps in need of service but a very solid watch. Without bracelet or other goodies like corfam or sun buckle. Happy hunting!
