I have an older IWC vintage minute repeater with the closed caseback (the one that is around 39mm excluding the faux repeater switch and crown). Just wondering if it is easy and possible to buy a similar dimension case and transfer everything (dial, A21J movement, etc) over into the new case. I really like the vintage looking dial on this watch but do not like the faux repeater switch so thinking it would be nice if i could just change the case to a normal case without the repeater switch. Any advice is appreciated. Thanks!
