As an amateur Russian watch collector I like both of the first two watches. Although there are signs of fading on the dial of the Signal, I dont think it is excessive for its age. especially the red, somehow red always seems to fade very fast. If you place yourself back in time in Russia when these watches roamed the streets, I think those that were preserved to look like this watch were the lucky ones and we are fortunate to get them in these conditions. Personally, I like the second watch better, which, please correct me if wrong, is a Volna, supposedly one of the best older movements made in Russia and based upon the Zenith 135 chrono. I think they were produced for only about five years because of high costs. The last one is a cheaper Zim- not interesting at all. Hope I didnt mislead you!
