Have had a 44mm PO rep with Swiss ETA 2836 that has been working wonderfully for about one year. Then this happened.
Watch still runs perfectly and I can insert and screw down crown as always had been able, but crown/stem is no longer able to adjust time or date. ?? Looking for some guidance. My last and only experience with repair ended with MD2020 and that was a disaster. BTW the prior reference was with a different watch....this PO has never been opened or serviced.
Thanks a bunch, I appreciate any direction that can be given!
