Slava 2427 automatic movement

The design incorporates two mainsprings (first photo). Not sure if this is common or not, or what the purpose of making it like this would be.

I think they put the extra spring for a longer power reserve.

Possibly. Online it said the watch has a 40 hour power reserve, though I’m not sure if that was considered a lot back in the 70s.

Oh ok then I don’t think it’s for the power reserve. Hmm this is a good question. If you find out would you please let me know?

Looks like it was to make it more accurate. The two mainsprings provide better energy distribution.
