Remove the plate to reveal the gear train. The second wheel has the pinion next to the mainspring barrel and the gear on the front side, driving the third wheel, onto which the minute hand is mounted, and through which the center wheel for the second hand comes through. The third wheel drives the fourth wheel. You can see the pinion of the fourth wheel from the front. Having driver gears on both sides of the pillar plate is an unusual feature. The steel gear on the other (right) side is part of the winding mechanism.
Removing the barrel plate reveals the barrel, which can be removed without taking the entire clock apart, a great design feature.
Remove the rest of the parts for cleaning and repairs as needed.
This clock has not been serviced for decades and needs to be serviced before use. There was rust on the pivot of the centre shaft, which would soon cause the clock to fail. The Mig clock on the previous page had the same problem.
This clock is built like a tank, (pun intended). Every collector should have one. I believe this clock is also a copy of a Jaeger Le Coultre clock.
The balance wheel is medium grade.
The last photo, which I found on the internet, shows the escapement in a Jaeger Le Coultre aircraft clock with chronograph, probably from the 1940s. The bridge for the balance wheel looks similar.
