Sea, since it says "quartz" I agree, you will probably be able to just buy a new movement for it and have it installed.
Now, if it was a wind up from the 40-50's..................
Oh yes, that Mickey Mouse alarm clock I received as a kid, who knew then what it would cost today.
Reminds me of a scam I heard about in the early 1990's, Returning Airforce vets and family's from Germany would bring back these huge elaborate grandfather clocks. The weights were the size of your head. The scam was they were told that the clock had to cleaned every 18 months and given a list of company's all over the USA to come to the home and clean it. Cost from $500.+
Up in Dover a near by town there is a small Museum with one room that has grandfathers that go back to the 1700's I asked the Docent how they could afford to have these clocks kept in good repair as they all ran and kept good time.
The old fella, looking as old as the clocks gave me an odd look and said that every couple years they very carefully vacuum them out and oil the workings with sewing machine oil. Just a few drops are needed. I asked what was used before the oil was invented and he laughed and said perhaps unsalted lard, or whale oil.
What a scam, but they are out there you know.
