Radiator 0 Posted January 27, 2013 Hi, I have a replica IWC with an Asian J21 auto movement, but the rotor has popped off and I can't get it to stay on. My question is, if the auto movement is not working can I just manually wind it a few times a day and still use it? Thanks Share this post Link to post Share on other sites
NCRich 13,804 Posted January 27, 2013 If that is the only thing wrong with it you should be able to wind it 30 or so times and it will run a couple days. Share this post Link to post Share on other sites
Radiator 0 Posted January 27, 2013 That's good news! I did read a few older threads on here about how you shouldn't manually wind auto movements as you may damage the mechanism? Share this post Link to post Share on other sites
AS90 5 Posted January 28, 2013 My PO was unwinding itself so I fixed the rota with sticky tape and manually wind it. Works great. Share this post Link to post Share on other sites
greg_r 83 Posted January 28, 2013 Yep - actually there's a few reps around that use standard 21Js converted to manual wind. Share this post Link to post Share on other sites
Waipio Jeff 0 Posted January 28, 2013 That's good news! I did read a few older threads on here about how you shouldn't manually wind auto movements as you may damage the mechanism? more so for the A7750 movements.

Haltec 0 Posted January 28, 2013 It's commonly known as "Hack" feature on Auto movements, and IMHO on genuine mechanisms in 80's was present in "higher class" watches only.... BR Haltec Share this post Link to post Share on other sites
onionbag 1 Posted January 28, 2013 FYI "Hack" is an old military term, it refers to the function of a movement whereby you can stop the seconds hand and synchronise it with another timekeeper. Share this post Link to post Share on other sites

Sent via mental telepathy from my Samsung Galaxy SIII with Tapatalk 2. +1 The A7750 is a very delicate movement. On the other hand, the Asian 21j is a workhorse. I wind all my auto watches about 10-15 times before I put them on every day. Share this post Link to post Share on other sites
