I watched a Heuer Computer count down about 12 months ago. It fetched a very healthy sum as it was in mint condition. Cal 12. It came with the original box and papers and the warrantee page from the original sale. Even the original braclet. It looked too good to be true, but I think it was the real thing. Must have been lost down the back of the couch for 40 years!

It was great to see just how that had been packaged at the time, as it was all there. Stunning.

As you say, very rare to see old watches with all its associated paperwork.
Watches like these, that are in very good condition (I agree with Fred on the first one) fetch a good to fantastic sales price and with little or no provenance. I am not a connoisseur, which is easy to tell, so I would have a dry mouth and sweaty palms bidding on one of these.
Leads me to ask this, and with apologies to anyone here who might be offended, as its not intended. Has anyone ever written the equivalent of a Catalogue Raisonné for Bretiling?
