I am glad that JLC is providing this service, although it sounds like they were doing some of this service before and are now formalizing the process. I do think it would be good to offer a certificate of authenticity, as that is what is also needed (right?) when a watch comes without or has lost its papers. I would love to see additional information, as you suggested Nicolas, such as the location of the original sale, the number of pieces made and the years of production of the model. Ideally, i woudl like to see a combined document Extract from the Archives with Certificate of Authenticity, understanding that yes, you would have to send your watch in to MJLC for authentication -- but for that sacrifice, and cost, one should then get a complete document.
But the important point here is that MJLC is creating yet another way in which it supports its community and the collectors, of which, I think, it does an admirable job.
Thanks for sharing this, Nicolas. It must be a happy day for those of you collecting the vinatge pieces, no?
