How old is my Vostok?

[time4seiko]

Does anyone have any info on how to establish the age of an older Vostok Amphibia?

The newer models no longer show a serial number on the back, but the older ones do...
(the back plate is on upside down😳)
I wondered if the number sequence may relate to age, same as Seikos. Any info gratefully received 😀

Apparently the SN has no bearing on manufacture date, makes it harder for sure.

Thanks for the reply Groundhog66.
These aren’t to everyone’s taste, but they certainly are sturdy and reliable, if rather quirky, and are right ‘up there’ in terms of “ Bang for Bucks”, and make great beaters!😀

I recall reading somewhere that the serial numbers apparently stopped being stamped after the break-up of the USSR.

I did a quick search on google and the earliest reference to the Scuba Dude I could find was around 2009. 

Can anyone find anything earlier? 

I have 2 Scuba Dudes that I got last year.  Interesting watches.

Pre 1991.

The CCCP dials finished then.

Beyond that, it's hard. I'm guessing late 80's. No older
