The seller stated that the clasp blade was a 78350 which is from a non flip lock 19mm bracelet. This is a bracelet made from parts, and while it may be in good shape, and function properly, it's not correct. It's all Rolex, but it's a franken, and consequently not worth as much as a correct 93150. Bracelets like this are not as uncommon as you would think. Folks buy a Rolex watch, years later something on the bracelet wears out or breaks, they take it to their local Rolex watchmaker, the watchmaker has a lot of old parts, and he uses what's available and fits. Owner gets his watch back, bracelet is fixed, and the owner doesn't care a bit that the numbers don't match. I bought a 16750 about 10 years ago, from 1986. It came with and incorrect clasp from a Jubilee, rather than the correct 78360 clasp. I'm sure in the first 15+ years of it's life, something happened to the clasp and it was replaced with the jubilee clasp. Probably wasn't a problem to the first owner, but I wanted it correct and I searched for a long time before I found a correct year clasp. Lesson learned, you may get a bargain in the beginning, but to make it right you will end up paying more than you would for a correct one to start with. In my case, I got the watch for a good deal, so it worked out, but in the case of this Ebay bracelet, it's always going to be incorrect until you spend more money to get it right.
