Post subject: Easy ? about Seth Thomas 1942 Navy clock
I just purchased a Seth Thomas Mark I Deck Clock. It seems to be running great. The dial/face also says "U.S. Navy" "N 18324, 1942"
The back of the movement looks like (except for being polished)
I'm a novice when it comes to mechanical movements.
The top center is the adjustment slot for when the clock is running fast or slow.
Below that and to the left is a hole that says "stop" and appears to be missing the small wheel (not missing in the above photo, missing on my clock). What is the purpose of that wheel? I assume it stops the movement, is there a time when the movement would need to be stopped, like when adjusting the speed or setting the time? And where can I get a "knob" for that location since mine is missing. The hole has a rod inside with fine internal threads.
Below that is the "set" which uses the key, and then bottom center is the "wind". How much should I wind it when the time comes? I'd hate to wind it too much.
To the right of the "wind" hole is an arc shaped slot with a switch in it. The movement doesn't say anything near the slot, so what does it do?
Here's my clock
If anyone has any other interesting info about these clocks, let me know. All I know is what I've seen online. Navy ships clocks. I think 8-day, 11 Jewel movements. Based on the date, made during WWII.
Thanks all
