MrAZ 0 Posted January 11, 2016 Hi all, im looking to buy a new stem for a 21j movement but need help picking out the right one for the movement. Here's a picture of the movement and the stem along with the link to esslinger who I believe has the correct size. Any advice would be appreciated. http://www.esslinger.com/genuine-chinese-mechanical-replacement-watch-stem/ Share this post Link to post Share on other sites
