Howdy y’all, A while back, I was daydreaming of a nifty wristwatch. It would have years of battery life, with an MSP430 microcontroller and RPN calculator. It would be able to receive and transmit on amateur radio frequencies, in a variety of digital modes. It would look spiffy. So I built the damned thing, and it’s called the GoodWatch. I began by disassembling the Casio 3208 watch module from a Casio CA-53W calculator watch, and measuring its circuit board which you can see on the right.
