Hello fellow horology enthusiasts!

I’m in need of your collective expertise. I bought a Molnija pocket watch during a visit to Russia in 2002 and recently rediscovered this treasure. I’m including photos for context.

While the exterior showcases the expected mechanical elegance of a Molnija, the interior surprised me with an electronic circuit tailored to play the Russian anthem. This has led to several questions that I’m hoping you can help with:

  1. Can anyone help identify the model and its potential manufacturing era?
  2. Is it typical for Molnija watches, or any pocket watches from that period, to include electronic components for such features?
  3. Given that I purchased this watch in 2002, is it likely that the electronic module was a later addition or could it be an original feature?
  4. The watch is currently not running. I’m assuming the electronic melody function is separate, but could an electronic problem possibly affect the mechanical operation?

I’m looking forward to your insights and thank you all in advance!
