I felt this needed a separate thread. I have long been using my own system for grading Speedmasters under consideration. I find it helps me to focus. The back end of this system is an untidy collection of notes but based on a thorough system that when followed has produced good results for me. The trick, is to distil a usable and useful simple document from that jumble of information. Now that I offer it is looks simple: And This is the watch: I deliberately chose a dreadful example to make sure I demonstrated that the certificate catches everything. What the paper does achieve is to confirm that parts correct or not. (Mostly not in this watch). I am happy to discuss this, but remember I have no profit motive here, nor do I especially want to start a TPA business. However I think they are inevitable - imagine if someone could do it for all those Rolex GMTs, Subs and Daytonas out there, and indeed how many would come back with unexpected problems. In other words my own little area of focus, Speedmasters is miniscule compared to the market for Rolexes, especially if the service costs $400 to $1500 each (That is what Gemstone labs charge). Another issue might be the physical location - to give a proper evaluation I would need the watch in hand, and that might be expensive in transport. The gem people do it, and if someone could set up a Rolex TPA service in New York I bet they could pay the rent. It might be a bit boring, though - looking at Rolexes all day. But I am sure someone is going to do it soon. Simplicity is the key. Any way I go into more detail on the blog, but I am interested to hear if people would use a service like this.
