I picked this up at an auction, thinking it would be a neat complement to my Waltham collection.
This is a model 1910, size 23, 7 jewel 8 day automobile clock. The main parts of the case are likely original, although the bezel glass looks like a bit of a hack job. Not sure exactly how these "fitted" into the cars, so don't know how original the bezel is.
It dates to around 1915, the heyday of the Model T. Would love if anyone has a picture of one of these actually mounted in a dashboard.
Based on the gouges in the dial, I'm guessing that the retaining screws in the bezel originally went into the little slots around the edge, and sent in far enough for the vibration of the car to cause the gouges. As a desk clock, I don't have to worry as much about the bezel, so I have it at the top (there's another hole in the bezel on the opposite side, but no screw).
As a watch, it's a pretty simple design. Two barrels drive a intermediate wheel that connects to an otherwise normal watch train. You can see in the movement picture above that the escape and fourth wheel bushings have been drilled out and replaced with newer brass bushings. And under the loupe, the escape wheel bushing is worn oval again. Clearly this clock saw a lot of use!
The winding is likewise straight forward; similar crown wheel design as their other watches. Only one click. Both the click and the two winding gears held down only by a plate that goes overtop.
When I got it, it looked like it had been serviced in the same garage as the original car; there was thin sheen of oil over the entire winding mechanism and keyless works. But after a good ultrasonic scrub and some pampering at the benchtop spa, it's running like a champ and keeping perfect time (despite the wear in the escape wheel bushing). Waiting to see how long it runs for; I'm expecting much less then 8 days 'cause of the wear, but we'll see.
