As long as the watch is fitted with all the usual gen upgrades (crystal, crown/stem) & a good, reasonably accurate dial, most indy gen watchmakers (not a Rolex service center) will service it since few will be able to ID a gen-powered watch as anything other than a gen.
PMWF insert (1665 & 5513 inserts are interchangable)
Unless you are replacing the insert on an MBW, I would recommend that you measure you existing insert to be sure the PMWF insert will fit (there is little consistency between reps).
The quality of aftermarket hands is poor, so I do not know if another set from another seller will guarantee better results. As is the case with parts from DW, alot of this is luck-of-the-draw. You could order another set from another seller, but I would say there is a 50/50 chance that you will end up just repairing the hands.
A number of threads were lost following a software update of the site a while back. I just tried to locate the thread & was unable to, so I suspect this was 1 of those affected.
Take it back. If the AD refuses to accept it, contact Rolex.
Note - Those 'GELENA SHITINERAND' reps are well-known & any knowledgeable Rolex dealer should be able to ID 1 without having to open the case, which makes 1 wonder how/why an AD could have made such a mistake . Please post a good, clear macro pic of the dial.
