I bought a Casio recently and I was curious about the mechanism, but I couldn't find anything. The only detail that I found was the frequency of the crystal. Regarding the controller, the best I could find was a few posts with people theorising about it being an ASIC or an MCU. I guess Casio is good with secrets.

If you can talk Ken Shiriff (righto.com) into decapping one, they won't stay secret for long. On such a question I suppose he might not take that much convincing, though I only know him by his work. But intuitively for the age of the watch I would expect MSI or LSI ASIC on some kind of mildly exotic film process for the epoxy blob die-on-board packaging they used to do before true surface mount packages made it to consumer products.
