I have a Raketa with the 2603 movement and am curious how old it might be. It looks similar to http://www.horology.ru/website/horology/var/custom/File/pobeda_files/raketa2603d.jpg except the colors are reversed (gold dial, chrome hands/case). The only markings on the movement are 16 Jewels (at least I assume it says jewels - I don't read Russian), 2603, a logo, and 32474, which I'm guessing is a serial number. Case back has no markings of any kind inside or out. Interestingly enough I have no idea when this watch was last serviced but it's in near-perfect condition other than some marks around where you pry to open the case, and keeps time to within a few seconds a week - better than any other mechanical watches I own (which admittedly is nothing terribly high-end: A couple of HMTs and Seiko 5s, and one old GuB Glashuette, I find myself accidentally banging watches into walls too often to spend the big bucks on them).
