no0rmal 0 Posted April 27, 2015 Hi All, I'm having some problems with a 21j movement i have on a sub. I understand that the watch should be windeable by rotating the crown up on first position (before date and time adjustment positions) and it does give a feel of winding a toy (so i suppose it is right) but the problem is, it does not wind as the watch gets no power whatsoever from there. Also, if i wind it with the rotor by moving the watch around and then try to adjust the date and time, when i unscrew the crown, it loses all power (unwinds). I can't open it just yet, as I'm talking to the TD who got me the watch (who has been helpful, by the way) to maybe get it fixed, or looked at, so i can't mess around with it. I just wanted to know what might be causing this issue and if it is fixable or I am to expect replacing the whole movement. Thanks in advance! Share this post Link to post Share on other sites
