Need help identifying this watch

I got this watch from a flea market in Beijing over the summer. It’s a Russian/Soviet wind-up mechanical model likely from the 90s, as the watch face says “50 victory years” and the outer year/day of week dial goes from 1992-2012. The back cover has “950” in small etched numbers while the inside parts are etched with “2628” as well as “SU.” However, I have not been able to find any images or information for this model of watch on the internet. Could anyone help me identify what exactly it is?
