Our TimeWorks clock motor had been broken for a while but each time I tried to figure out what new motor to order, the technicality drove me nuts and I gave up. I don't know the names of clock motor guts parts to measure! Luckily, I hit upon Ronell. The website had very clear contact info, and got a reply the same day explaining how to figure out what I needed, as well as helpful links to three options. The part arrived today and my clock works like a dream!
