Crown Winding STEMS For AUDEMARS PIGUET Watch Movements Cal. 2121, 3120 etc – Swiss Made

A very, very important part of your movement that should be changed during service if you can. Over the years, stems are put in a lot of use and can also sometimes bend or get rusty from humidity … and carry that humidity inside your movement. These parts are getting harder and harder to find and, my advise is that one should keep a spare stem with their watch if they can, for future its future service needs. Do note that the Cal. 2121 will also fit Patek Phillipe and Vacheron Constantin 2121. Choose from the drop down menu and do not hesitate to contact me for any questions you might have.

Please do note that I do not accept returns for movement parts.
