J!m 289 Posted August 25, 2014 Hey guys- quick question. The 7750 and 7734: do they use the same pinion size for the sub dial hands? Having trouble determining that for sure. Either PM or post for everyone. Thanks in advance! Share this post Link to post Share on other sites
10:10 Watch Repair 1 Posted August 25, 2014 Why would they be the same? 7734: 1.4 .95 .27 .27 .18 7750: 2.0 1.2 .25 .18 .18 .18 Share this post Link to post Share on other sites
J!m 289 Posted August 26, 2014 Thanks for the info! So one of the subdials is the same (0.18) but one on the 7734 is larger (0.27). Trying to find some properly shaped subdial hands and there is a lot more available for the 7750 of course. Share this post Link to post Share on other sites

Yes, it's quite common with older movements that the 4th wheel is different from the minute counter. Share this post Link to post Share on other sites
