This 8 day wall clock had a broken strike train spring and other issues. It has a balance wheel which looks similar to those used in big old alarm clocks. Though not worth much, it's interesting.

The HOPE trade mark and the initials on the movement are from a Japanese clockmaker. So far I have no other information other than the national origin of the clock. Vintage? I'd say around 1890-1935.

Unfortunately, someone attempted to repair the clock in the past. Lead solder was used to attach the end of the hairspring. The solder flux caused corrosion.

Fortunately, I had a box of very old alarm clock parts. After many tries I found the right hair spring balance wheel combination to make the clock keep time. Of course before the escapement work, I had to replace the strike spring and clean the clock properly.

The experiments in attempting to get the clock timed properly with alarm clock parts took quite a lot of time. While waiting to see if the clock was keeping time, I tightened up the loose parts of the wooden case. The dial needed a little toughing up. Fortunately, my wife is a fine artist and she was able to make the dial look much better.

And here it is. Keeping time reasonably well. Of course, it's still not worth much money. But that's not the point.

Nice job to save an old clock from the boneyard.
