8 day clock
Hi All
My 8 day clock can not be wound.
Anybody know where to have it repaired?
I see online I can get a used one for about 100 dollars, but I don't know how worn it would be.
Thommen on the face.
Wakmann Watch Co on the rear case.
Thanks

Re: 8 day clock
The most common problem is overwinding. Will it run for a little while when you tap on it? If so, keep tapping on it to make it run and don't wind it.

Re: 8 day clock
My old original wind-up clock in the 170 would only work when the engine was running. I would set it as part of the run-up and it would keep good time the entire flight. It would stop sometime after shut down. I never had to wind it very often. I guess there was enough internal drag it needed the engine vibration to keep running.

Historic answered my inquiry... They are not accepting new work until after the new year.

My understanding is that most of these are basically pocket-watch movements. If you have a good independent watchmaker in your area, you might try him.

I have had instruments repaired by Century Instrument in Wichita. http://www.centuryinstruments.net. An 8-Day clock is $355 outright, $250 Exchange, $180 to repair yours, Core Charge is $105.
When Dad filled out the panel in the 170 back in about 1952, he got his instruments at Century.
