18238 Date/Day Change Question

[ajh77]

I had my 1990 18238 serviced by a very well known shop on this forum, LAWW.

I noticed when the watched stopped and I went to set it again by pulling the stem all the way out and turning the actual hands to set the date , the date indicator would turn white and not flip the date until past midnight, and the day of the week gets stuck in the middle of the word, but it does eventually flip and that’s really all I care about is that I wake up and the day of the week and date are correct. I am not going to bring the watch back for a follow up service.

What would cause this issue ?

Also, can someone recommend a place in Los Angeles other than LAWW where I can get this issue fixed, if I want to.

Other than that the watch is running perfectly accurately for time.
