I've never used the Longines archive extract but it has to be applauded for offering this as a free service, I have however used the Omega extract service which has a charge attached to it, that service was also good and included the Model number and Name year of manufacture and which retailer originally sold the watch and in which country.
I have also had good experiences with a company called Eberhard many years ago, I needed some parts for a old chronograph I bought at a local auction I needed a full set of hands a winding crown, and oval pushers, on the off chance they may still have these I wrote to them with the serial number and received a very nice letter back from them telling me that my watch had been manufactured in 1938 and was a two button 18ct rose gold chronograph and that they did have the parts and would be happy to supply them for 65 Swiss francs. Try doing that with any of the large manufactures, their response was a pleasant surprise.
I had the watch for many years but sadly I had it stolen about 5 years ago.
Thanks a lot guys ... I'll do some test and show the results.
I really love that dial though it's pretty stained and scratched so I'll try first with Rodico, Q-tips and distilled water and see how it goes.
There is no financial risk as I got it for cheap ($40 shipped) but those 1002 dials don't often show up on the net and are sold for much more, even if they are damaged ... plus I have a nice 5500 case that's waiting for a dial
By the way ... did anyone of you ever drilled an ETA 2840 mainplate to make place for Rolex dial feets ?
I'm asking because I have the case, the low beat ETA and a handset that could fit but I don't think I could ever cut the feets of a Beyeler Rolex dial
