I have been quite intrigued by the hybrid waveceptor watches from Casio.
1. They feature radio reception, so you don't need to correct for DST.
2. They feature GPS, so you still can sync to correct time when radio reception is unavailable
3. They run on solar power, hence no battery replacement required
All of the above features make them the most advanced of the analog watches out there, a watch that is on time, all the time and at most locations (exceptions being where no signal reception is present) and a watch that keeps going. Anyone else interested in them? These are a few models.
