Looking at all those weird Casio's G-Shocks with all sorts of bells and whistles - I wonder if really usefull functionality was ever introduced?
Like - a solar-powered water-proof wrist-watch that has a set of ephemeris data for useful stars and planets for today. Accurate enough to be usable as a back-up to a proper chronometer and paper NA tables?
Would be really interested to buy one.
