Hi Rolf
No, it is a quartz pendulum movement. I had it hanging in my workshop and it accumulated some dust that i didn't like, I have since moved it upstairs. I just took the movement out and vacuumed the inside and outside. It should stay a lttle cleaner up here. As I said previously, I make stuff for myself, (I like the challenge) family, and friends. Most of the time a family member or friend will notice something I made or they have seen and ask if i could make one for them. I'm a pushover. I'm planning on making 2 more fretwork clocks, then thats it. I'll stick to my Intarsia or some smaller fretwork projects.
Maybe this type of fretwork will come back around some day. Probably not in my lifetime though.
Thanks for the compliment.
