My watch of choice at the moment is the
Casio Waveceptor
Under £30 for a watch that's never more than a second off the actual time, as it resets from a standard radio signal every night.
It would be nice if it have a better display ands was thinner. There's a least 1mm (perhaps two) that could easily be shaved off by losing the gap between the cover and the LCD.
But the Pebble doesn't interest me. It's bad enough having to constantly charge my phone. I don't want to have to remember to charge my watch every week (or probably more often).
