They are very wonderful clocks. I hope you are going to have a lot of fun looking at your one soon. Thank you for watching and for your nice comments.

Yes it is indeed very hard to make them run at the correct speed. But with time you can manage.

Owh did not know that. I always thought it was called an anniversary clock because you would wind it once a year.

Perhaps you are right. I remember on their tenth anniversary, my mother gave her aunt and uncle an anniversary clock (not like the bona fide mechanical one which you showed, but a quartz battery powered one with a faux torsional pendulum).

If you can't move it it's probably completely wound up. About the odly shaped metal piece I can't say much lot of clock parts are odly shaped.

Not really as long you dont move it unless it is locked and if you want to start it give the pendulum a gentle impuls in order to not damage the torsion spring. So if you want to start it just level it out like I showed and the gently start it up. Keep in mind even a not working one can work for a while because of the nature of the torsion spring but if it still works after 20min to half an hour it is probably okay.

Normally they should be accurate, yours might need some maintenance.

Well you wind and than you dont for a year. And the clock will work for more than a year
