I'm working on an ETA 1164 triple calendar movement and the day disc does not line up well with its window, see picture. The jumper action seems fine and there are three jumpers for the date mechanism which are all identical. Thus mixing them up should not matter.
Has anyone incurred such issues before with this movement? Is the only remedy to adjust the profile of the jumper?
Not exclusively, no, but this was one of their major production sites until 1993. If the watch says Great Britain, or made in Scotland or Made in the UK, or UK Time Corporation, then it was made by UK Time Corporation (a division of US Time Corporation, the parent company of Timex) who set up in Dundee in the late 1950s, and also produced other items (the Sinclair computers for example) at their Dundee site. During this time period, Timex also produced or used dials, mechanisms and so forth, made in France, Germany, England and even occasionally Switzerland.

Nowadays, like most volume producers, they manufacture mainly in the far east/China.
I figured it out. The point is to unscrew the crown and keep it in 0 position when pushing on the farthest/southern spot on the lever from the stem (close to the letter "p" in "push". Notice that the image above is when crown in position 2.
Chemical recation between markers and dial? Is it a plated dial?
Send an email to Zenith and tell them that you are a long term customer but are dissapointed; can you help? etc.
