[Vostok Komandirskie 650546] - Lemmy.World

Accuracy according to the watch accuracy app from the playstore : 5 sec fast a day.

I was able to adjust my Vostok similarly, but in the end the real timekeeping on wrist was waaaay off. Plus it was quite unstable, ie. one day it would run +7s, another +17, etc. Pain in the butt to adjust.
I bought this watch at poljot24.de, they regulate the watches before shipping www.poljot24.de/en/faq/
