Hi Guys, does anyone know what size winding stem I need for the 243? got a snapped one so need to replace it.
7750 stem should fit.
It will but there are several different sizes of 7750 stem. Gone to watch smith now lol.
No, thread width........
Gotcha! I remember the swiss stem being thicker than the asian clone, but I can't confirm this for the 243 clone movement. Hope your watch smith fixes your issue.
