Soviet watch crystal size list

Because this information is nearly impossible to find, I’ve made a list of Soviet watch glass sizes as far as I’ve personally replaced and confirmed them as fitting. Without this information it’s often necessary to buy 2 or 3 different sizes to find the one that fits. Even with this information there is sometimes 0.2mm variation in the same model, so take these sizes as a starting point.

Watch crystal sizes are commonly listed in units of 100µm (1/10th of a millimeter) so for example size 312 is 31.2mm. The term “crystal” or “glass” is conventionally used even though the Soviet watch lenses were almost always acrylic.

Vostok

Vostok is still in business of selling amfibias and komandirskies, so original crystals and other parts are still available from them for many models.
