Vintage Soviet Luch Keychain Alarm Clock Repair & Testing #EDC

This video is about a 1970's or '80's vintage Russian Pocket keychain alarm clock.
It was made by the Luch company in what is now Belarus.
Measuring only 2" by 1", it used a mechanical (wind up) watch movement coupled with a battery powered alarm.
We'll disasemble it to see what's inside, replace the battery, and test out the alarm feature.
