Cornavin Early 1980s Calendar Manual

Produced at the gloriously named Second Moscow Watch Factory by Slava in the twilight years of the USSR, this watch was slated for European sale under the Cornavin brand name. It’s certainly an interesting design, with its unusal hexagonal case. The Slava movement is also unusual and quite innovative, with an indirect drive mechanism, oversized balance, and twin mainspring barrels for space efficiency. It also has the customary soviet industrial finishing on the movement parts. However, even if it isn’t very pretty it still tells time well!
