that is a vintage model i have one that i wonn on a PT raffle years ago, i did a bit of vintageising after i dropped it and also replaced the movement (new Molnija19j) with a vintage molnija 17J because A, i broke the new one and B, the older one has a microstellar balence and looked nicer. I brushed the case and fitted a very cheep high plexi glass to it. I belive a lot of the collectors can still source this one.
And here is a shot for sizecomparrison
