The 666 Refinished in Green.

Repaired the tines holding the tiles back. Thanks for the tip.

Hi guys,
I have found a Sankyo 451 Digital clock at my local thriftstore. However, upon opening i was met with a completely disintegrated / dissolved main motor gear. While these gears are known to break, i cant even measure it to find a replacement. I was planning on printing a new gear with my resin printer, but without exact measurements this will be quite difficult to do. Online i saw some replacement motors, but they run on 50Hz, and i live in europe (60Hz).

Does anyone have the measurements of this gear, or has printed these gears before. Does anyone have the same clock that can help me out? Would be great to ger this clock working again!

Hello! I recently found an old Copal flip clock in Japan in an old house I bought. It's showing its age but works and looks like a 201, although the label is old brown paper. I carefully opened the back and found no other markings. Chatgpt just says it could be pre-101 or a poorly documented early variant / likely an early transitional unit before model standardization. Just wondering if anyone knows what I actually have and if it has any collectable value. Thanks!
