There's more room for creativity with digital technology. The most accurate quartz movements drift by around 5 secs a year. Chip scale atomic clocks are accurate to around 37ms a year. Current chip scale atomic clocks are still a little too big for watches, but some applied creativity might change that. Personally I don't care about clockwork, but I think having an atomic clock on your wrist would be quite cool.

An interesting race will be improvements to the local oscillator versus continued size and power reductions for grabbing a GPS signal every hour to correct your clock. No predictions here, though, of course, an increasing number of watches do have GPS for other reasons. (And the GPS solution doesn't help you if you live on a submarine)

  > grabbing a GPS signal every hour RFID-style sync to some device with accurate time (probably a phone) would be the best way to keep an electronic watch mechanism accurate on a day-by-day basis.
