Just purchased a Heuer Carrera 1153 with a cal. 12 movement on Ebay. First time I purchased a vintage Heuer, so not much experience with these type of watches. I brought the watch to a watchmaker because I noticed the stopper was sticky, and I wanted to replace the damaged orange second hand. The watch came with a receipt for an overhaul from 2015, but my watchmaker just informed me the watch needed a full overhaul. Total estimate to overhaul the watch is $1,650 and 3 months to do the work. I know servicing a vintage chronograph is not cheap, but is this the average cost to overhaul a cal. 12 movement? Would it be better to bring the watch to Tag Heuer at this point? I'm thinking of returning the watch, but even with the added servicing cost, the ebay watch would be cheaper then if I bought the Carrera through Vintage Heuer.
