Thanks for the information. The same antique dealer had a variety of aircraft dash gauges but the clock was the only one that functioned. Being a watch collector, I had to have it. The movement runs continuously now and will keep accurate time in horizontal and vertical positions without coaxing. I’m going to have it serviced because the movement is probably in original condition which means the lubricant has broken down and the setting knob functions intermittently.
My brother in law was a Squadron Maintenance Officer and flew F86 and F101 fighters in the early 1960s. The F86 was his favorite and he called the F101 a “flying piece of junk.”
