I bought it from a collector a few years ago. He had it for 25 years. From his notes: Russian military comparing watch; date “1-64”; 22 jewels, gold plated movement, hand engraved; silver satin finish dial, graduated to 1/5 second; similar to Hamilton model 22. The inside of the case back is decorated. There is some more info about the movement but I can’t decipher his writing lol. The swiss type push set is broken off but can be pushed with a small tool like a screwdriver.
