0100V Crystal back for Vostok Automatics
Crystal back - perfect for the Vostok Automatics
This crystal back , made of stainless steel with mineral glas has a diameter of 35.7mm and fits to the Vostok automatic models.
It offers a clear view to the beautiful Vostok Automatic caliber - it is worth watching this caliber at work!
This crystal back, which is fixed by the screw ring affects the water tightness of the Vostok Automatic models - of course, a Vostok with such a crystal back still suitable for everyday use, sweat and washing hands, etc. are not a problem - but you should not shower or swim/dive with it anymore. ( or change the closed back again when you go swimming...)
