My Russian clock won't run. Any recommendation for fix or replacement?

A full spring wind gives at least 3 days operation and, with a diurnal variation of temperature (20 ± 5) °C, the timekeeping is ± 20 s per day.
The reliability is quoted at 94% over 2000 hours between 20 ± 5 °C, which is only about 3 months continuous use? So not sure how well made it really is, even allowing for intermittent usage in a high vibration environment.

If you have a letter 'B' on the right side of the dial the hands & numerals are painted in harmless phosphorescent paint and a 'K' signifies just white paint was used.

There are several on Ebay for $150 or less if you decide to replace it.
