Wiz 0 Posted May 14, 2011 Just saw a dealer offering a watch with "hand wind 7750". I'm quite surprised to see this, as I've always been told you should avoid hand winding a 7750 asian or swiss. has this movement been modified in some way? Share this post Link to post Share on other sites
KBH 7 Posted May 14, 2011 Yes, in fact i have a manual wind ETA 7750. By removing all the winding gears, you are basically converting it to a 7760 which is a manual wind chrono. The important thing is that you not only remove the rotor but you also remove several other gears and pieces which are the ones that would normally strip from winding.

trailboss99 997 Posted May 14, 2011 Yup, you remove the entire auto module thus removing the source of the problem. Share this post Link to post Share on other sites
graman 2 Posted May 14, 2011 Would that also mean that a 7750 with subdials only at 3 & 9 would have the same pattern as a 7733?? Share this post Link to post Share on other sites

powderfreak 0 Posted May 15, 2011 'n how's the reliability? Better than the usual 7750? Share this post Link to post Share on other sites
Drhulee 0 Posted May 15, 2011 I would love to see this documented! Me too 'n how's the reliability? Better than the usual 7750? Well the removal of the gears that usually "break down" with manual winding would make it much more reliable and longer lasting than before. But I still love the ST19 for all my manual wind chronos, it just looks great in a display back Share this post Link to post Share on other sites
