I bought an Elgin 760 that turned out to be non repairable. I was able to locate an older 760 movement that had been taken out of a gold watch. The movement I had put in is actually superior to the original because it does'nt have the cost savings feature that caused the original movement to self destruct. Is it safe to call it original? While I was looking for a movement I saw a chonograph movement on offer from a quite valuble watch. Recently I came across a NOS stainless steel case, dial, and crown from the same manufacturer assuming it's a match would it be legitmate to construct a watch. I'm not thinking about doing it but with the number of movements available what's to far?
