Strange winder behaviour for 3940
My 3940 advances the dates pretty erratically when on the winder. If it sits on the winder for a few weeks it is always some dates after. All other indicators advances correctly though. When on the wrist for an extended period of time it also works flawlessly. Anyone experienced anything similar?

If it’s functioning perfectly on your wrist ....
You probably have a problem with your winder.
I would think so too,
but I really cannot see a winder malfunction that would result in this behaviour...
can you explain the problem in more detail?
"If it sits on the winder for a few weeks it is always some dates after" Do I understand that to mean that your watch is gaining significant time (dates) when on the winder?
Update
I have always had my winders set in around 650 tpd and it works fine for all my watches. It seems like when I increase tpd for the 3940 to around 1000 tpd it works fine (and also when worn) but not on lower settings. Probably time for service soon but isn...
Very odd as they all linked...if there is insufficient
Power due to low TPD cant understand why it will stop this then power up change date etc
Update II
Upon further investigation (two years later…) I believe that the problem came from not setting the calendar correctly. I.e. functions in the correct order. If I follow the manual to the point, I have not had any problems, even on the winder.
