curlflash Posted September 14, 2015 Report Posted September 14, 2015 Hello hello,I recently bought this case back for my project and as you can see there is no thread...I dont know why the guy did that...Could you tell me if possible to make thread on this case back and if a watchmaker can make this?Tks for you help and sorry for my english
alligoat Posted September 14, 2015 Report Posted September 14, 2015 Send it back!A watchmaker wouldn't be able to machine threads on there- might ask jmb if he can.
freddy333 Posted September 14, 2015 Report Posted September 14, 2015 I disagree. A watchmaker could probably thread the caseback, but you should not have to pay a watchmaker to do that. It should have been done by the factory. Because it was not, the part is 'defective' & should be returned to the seller for exchange or refund.
curlflash Posted September 14, 2015 Author Report Posted September 14, 2015 (edited) tks very much alligoat and @freddy333.@freddy333, It' an original caseback (Tudor ref.79090) but the guy has filed down the tread (why?...I don't no). Tks Edited September 14, 2015 by curlflash
KB Posted September 15, 2015 Report Posted September 15, 2015 I'm betting the case back he sent is off a cheap digital version and is simply pressed on. Ken
freddy333 Posted September 15, 2015 Report Posted September 15, 2015 What Ken said or it is a defective aftermarket. Rolex (Tudor) would not release a caseback without threading. Just no.
curlflash Posted September 15, 2015 Author Report Posted September 15, 2015 Tks very much for your answers butI think this caseback is an original.It's the deal on Ebay : http://www.ebay.fr/itm/111754560933?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AITI take this because for the price...no good option :/
automatico Posted September 15, 2015 Report Posted September 15, 2015 It would be very difficult to machine threads on this case back. You would need to mount it in a lathe by the shoulder inside the case back, center it, make the proper cutting tool, have a perfectly timed automatic feed, and cut the threads from the base of the case back to the outside with zero mistakes. You only get one shot at it. We see replica case backs and unsigned generic case backs for sale for $20USD and this gives the impression they are cheap and easy to make. Not true. The machinery needed to stamp the blanks out and machine the case backs is sophisticated and may cost over one hundred thousand USD.I also have serious doubts about it being genuine.Imho in its current condition, it is a $5USD case back. It should be valued at what it is, not what it could be.
curlflash Posted September 15, 2015 Author Report Posted September 15, 2015 Ok, I see... :/. I will contact the seller to refound this purchase. Tks a lot for your help everybody.J.
