I'm a newbie here so can't give you an expert opinion, but I think this is a) very beuatiful, b) very rare watch. Not only in west, but also in SSSR. You can assume that ratio of "ordinary" vs. solid gold watches was in SSSR the same as in the west, but more likely smaller. Vimpel watches are rare; I just checked ebay; 8000+ "soviet" watches turn up, but only 9 Vimpels, hence 0,1 % of available soviet watches are vimpel (there are many Luch and other watches advertized with word vimpel, but not bearing this mark, I didn't count these, of course). Vimpel is considered a premium/luxury soviet brand by many, so that makes them more desirable and hence they are scarcer than many other brands that were made for peasant and worker's masses. The short time of production adds to it's rarity and desirability among collectors (and desirability increases rarity on the market). It's simple and elegant design is very attractive. Other members can say about their mechanical quality, but I think that movement is used in other watches too, i.e. Luch and Poljot premium models.
