The movement is a brutalist utilitarian cousin of the Seagull No. ST21 movement, and was made on the same machines sold from Switzerland in the 1970s! You can compare the two hand-winding mechanical movements in the first two photos, which is fascinating to me. It's a wrist-worn microcosm of Russian vs. Chinese design in watches. 

Cool Features: 

- Hand-winding and hacking (if you back-turn the crown slightly)

- Features both a chronograph and an internally rotating compressor style Bezel

- Unique / rare: you won't find this "Sturmanskie" model sold anywhere else, they've disappeared since the last were manufactured years ago

- The dial is printed with Slavic Cyrillic script 

The watch is in perfect working condition, barely used since last service, and is very robust by design. Poljot24.de offers servicing for the watch, should you need it.
