Hi Odessa200,And this happens when people turn the hands backwards. Never do that! Because if you do you need to remember which watches it is safe to do and which not. Cause this is too much for me to remember I decided never do it.
9-12 maybe safe (a Vostok expert may opine) but if you continue you may get this issue. Look how this part connects to the eccentric. If it gets a bit jammed in this position as shown it will break this spring.Hi Odessa200,
Can you elaborate please?
Do you mean it's not safe to use the '9-12' date change on Vostoks?
OK thanks, the picture does make it look like running it backwards might not be wise.9-12 maybe safe (a Vostok expert may opine) but if you continue you may get this issue. Look how this part connects to the eccentric. If it gets a bit jammed in this position as shown it will break this spring.
So, like a Seiko then?The date mechanism will still work without it but the date will roll over slowly instead of "snapping" on to the next date.
Hi JP 1999,
Hello Jim, I'd better mention that the calendar cam spring you show might not work...the OP needs an older style calendar cam spring that has a built-in stabilizing stud, this stud fits into a hole on the mainplate...Hey jp1999 drop me a PM and give me your address..... I will send you one Comrade.
When I first came to the F-10 I needed a part I could not find and mariomart was kind enough to send it to me so I am returning the favor.
It might work if the screw is tight enough...around 2000 Vostok redesigned the mainplate and one of the things they changed was to put the locating pin on the mainplate rather than on the spring itself, all my Vostoks from the 1990's and earlier have the locating pin on the actual spring which would be correct for the OP's watch...a mid-1980's to early 1990's Zakaz Komandirskie 341201...I have only seen this type and these are the only type I have, I did not know there was a version that had a locating pin. I can send it to him if it may work...
what do you think Avidfan.
I'm sure a pin could be fabricated to fit, but that would be real watchmaking...Wow I had no idea. Evidently I have not had that part fail on one of my older 24XX as of yet.
A pin could be fabed and soldered in, even epoxied in so as not to take out the temper or you could glue it and screw it into place?
