cal 750 day date alignment question

[dansutterlin]

Over the weekend I reassembled my Cal. 750 day date movement. I notice that the day and date do not change at the same time. I admittedly did not spend a ton of time trying to figure out how to get these to align but figured I would reach out and ask if there is a trick to it that someone could share? I can provide photos if it is easier to illustrate on photos.

The dial washer isn't used on these day/date calibers, as the upwards travel of the hour wheel is already constrained by other parts.

In order to sync the day and date change, assemble the calendar to this point:



In the hand setting mode, turn the crown so that the time advances until the tooth on the date indicator driving wheel is just touching the tooth of the date indicator as shown by the arrow on the left. Then adjust the day indicator drive wheel finger...

Thank you sir. I did try searching but I couldn't come up with the right collection of words to get your thread to pop up. I will try this tonight and report back.
