presence00 0 Posted February 10, 2013 I have a relatively new sub no date from Reg. Out of the 5 I bought for myself and my brothers(and brothers-in-law), mine had the most issues. I've regulated it so that, when wound, it keeps reasonable time. However, it seems to unwind within a few hours, so much so that it will unwind at work or while I sleep if I'm fairly still. Instead of replacing the movement (the next step), I'm thinking of trying to convert it to a hand wind. Can anyone point me to a guide on how to do this? My searches were not successful, sorry. If there is not one, could someone walk me through the steps? It's an asian 21j. Thanks! Share this post Link to post Share on other sites
AS90 5 Posted February 10, 2013 Stop the rotor from moving with some sticky tape. It will now hand wind but not unwind. Share this post Link to post Share on other sites
Realism 72 Posted February 10, 2013 Or just remove the rotor Share this post Link to post Share on other sites
fatarms 7,779 Posted February 10, 2013 Maybe just take the rotor off? Nevermind, Realism's idea is better. Share this post Link to post Share on other sites
AS90 5 Posted February 10, 2013 Removing the rotor will not solve the problem. You have to use the rotor as the anchor to stop the spring unwinding. Share this post Link to post Share on other sites
presence00 0 Posted February 10, 2013 Thanks for all the suggestions! What if I suspect the spring unwinding is the current problem? Share this post Link to post Share on other sites
JohnPilot 1 Posted February 10, 2013 Removing the rotor will not solve the problem. You have to use the rotor as the anchor to stop the spring unwinding. No you don't. Simply unscrew the rotor and take it out. Share this post Link to post Share on other sites

Simply unscrew the rotor and take it out. If you unscrew the rotor the spring will continue to unwind. It is not worth repairing a 21j, so securing the rotor is a good fix for this common problem. I have done this myself. Share this post Link to post Share on other sites

I have done this myself. I don't think that is true... lots of people removed the rotor on loud 21j movements (me included) and never heard of that before.

Realism 72 Posted February 11, 2013 There's no weight to wind the spring if there's no rotor no? Share this post Link to post Share on other sites
JohnPilot 1 Posted February 11, 2013 There's no weight to wind the spring if there's no rotor no? You will have to wind it by hand, handwound watch. Share this post Link to post Share on other sites

Crusader 0 Posted February 11, 2013 If you remove the rotor, it will behave like 6497 movement. You give it a few winds and it will be unwinding itself in the next 48 hours. No need for fixing the rotor. Share this post Link to post Share on other sites
AS90 5 Posted February 11, 2013 (edited) The watch is unwinding too fast so the click spring is obviously broken! The mainspring is strong enough to spin the rotor backwards, unwinding the watch. If you secure the rotor the spring cannot unwind, but can still be manually wound. If you remove the rotor the spring is free to unwind.

Once the movement is winded, it will unwind itself until it runs out of power. Some removed the rotor on 7750 movement, because it tends to be loud and all is fine, no need to glue the rotor.

I don't think you understand the problem. It is BROKEN, the click spring is faulty meaning the watch is unwinding in a couple of hours. I think you are totally stupid.
