Today I thought I would do something different so I started on my friend’s 1959 Cadillac clock and a Studebaker clock. These clocks are driven by a spring that is wound via an electromagnetic coil. When testing the Cadillac clock nothing happens and when testing the Studebaker clock the winding coil keeps engaging and does not wind the spring.

Here you can see the winding mechanism! I try to remove it, but it’s stuck… The glass in the front chipped a little in the process and I consider myself lucky the glass did not shatter! I can dismantle this from the back so I will continue.

The hairspring is fixed in place with glue! I do not want to risk breaking it so I clean the jewel and other pivot holes with pegwood and Rodico.

The ratchet click is worn and not catching the ratchet wheel hence the non-stop winding action when power is applied.
Here is a little video of the mechanism.
Now for the Cadillac clock. I have two clocks so I will make one out of the best parts from both.
I remove the winding mechanism.

Here you can see the Cadillac movement in all it’s glory. In principle exactly the same as the Studebaker.

I removed the movement plate and you can see the gear train. The hairspring is fitted with a little pin, so I removed it for cleaning.

This is the top jewel for the balance staff! The balance staff is shaped like a cone and end shake is adjusted with the screw it sits in.. Crude but it works and makes for a super solid balance staff!

Needless to say I see no need in polishing the movement plates or wheels. This is about function only! 😛

Dial and hands go back onto the movement. The hands were nicer from the donor movement so I used them!

Here you can see the bezel, the crystal is full of small scratches and could do with a little polish.
Here is a little video of the Cadillac clock:
I have 4 studebaker clock. Could you repair them. I live in France
Hi Malo,
Send me an e-mail to m@mitka.co.uk and we can discuss it:)
Best regards,

I would never have thought about clocks in old cars as something to get excited about, but these two are gorgeous. Thanks for posting this, and let’s have some more!
