I've got a 61 Olds I need to try and do a quartz conversion for. Guy on Ebay with all the kits only has them for Borg clocks, this one is a Hamilton Watch Co. He doesn't have a kit for it. Anyone know someone who does?
I don't know if this is any help to you, but on my '49 Cadillac I used a quartz movement from the craft store for a conversion. It now runs on a AA battery, but it is accessible through the top of the glove compartment. It now keeps perfect time! ~Alden
Look at almost any clock in your house. That's similar to what the craft stores have. Cut down the hands and install. my 2¢
This might be a long shot but Hamilton watch is still in business. It might be worth a call or email to see what they recommend. They might even be able to rebuild it. That said, if it's a points type movement you might have luck cleaning them up to get it running again.
