The Chalet version was not too bad - just had to clean/re-oil, some small work on the music box timing with the governor and then some minor back and forth on the correct weights to run the clock. It did not come with weights when I purchased. Eventually, I found that 630 g. weights were needed to run it at optimum. That is pretty heavy for a one day clock. But even after cleaning, the lighter weights just did not work.
The Hunter's clock too more work this time. It was missing the proper music box governor trip wire to make it play music after the Cuckoo call. I had to purchase the trip from Timesavers and retrofit it on. This clock also has a side mount music box that uses chains thru a pulley system to make the dancers work. It was hard to get it all to work, about 40 hrs. The clocks that have a movement built with a dancer platform in the movement itself (like the Chalet clock) is MUCH easier to work. After fixing the music box, then all I had to do was basic clean/re-oil and a little bit of work on the Cuckoo bird door. A nice clock that was worth re-storing.
