Glass case back (large) VOSTOK AMPHIBIA KOMANDIRSKIE (GB-4)

Suitable for classic VOSTOK AMPHIBIA and KOMANDIRSKIE automatic watches

• stainless steel, brushed
• large mineral glass window ø28,5mm
• inscribed on the inside (looks silver from the outside) with the inscription "WATCH MANUFACTURER CHISTOPOL - 200m - special series

The complete movement can be seen through the large glass window, but also the movement fixation ring, which is made of plastic as standard. It looks visually nicer if the plastic ring is replaced by a movement fixation ring made of metal. Of course, this is only a recommendation.
 
You can find the movement fixation ring made of metal here.
