Yea would be nice to see more clocks alright. Can't help there much myself, have an old smiths bakelite mantel clock and that's my lot.
I also have a Mig fighter plane clock, based on a Jaeger LeCoultre movement. Not really a clock as such though.
Rejoice in the awareness of feeling stupid, for that’s how you end up learning new things. If you’re not aware you’re stupid, you probably are.

Its mechanical so I just give it an old fashioned wind.
There is an electronic heater in it for high altitude stuff and it may have a light as well. It requires 27volt DC supply of all things. It is designed to take serious G forces and was fitted to a long list of fancy Mig(and Sukhoi) fighters over the years. Here it is in a mig 29
Its got various functions. 12 hour chronograph, second timezone in lower subdial and you can stop the whole movement if you like. It runs solidly for over 12 hours and stops suddenly. Pretty accurate too. Gains/loses maybe 10/20 seconds over a wind. One theory why it was a mechanical was the Russians fear over the massive EMF radiation from possible nuclear detonations nearby, so their aircraft were heavliy protected from that and a mechanical clock wouldnt be affected by radiation of any kind(beyond magnetic), whereas a quartz/electronic clock would be fried.Rejoice in the awareness of feeling stupid, for that’s how you end up learning new things.
