The Seiko Astron GPS Solar SBXA011 ($1340) has two features that are revolutionary; it instantly recognizes which time zone you’re in anywhere on earth, adjusting the time automatically to the local, and it never stops. The Astron is powered by light absorbed through the dial and a power indicator shows you how much reserve you have. And lastly it is extremely accurate. How accurate? Accurate to within one second every 100,000 years due to the signal it receives from Atomic Clocks and GPS satellites. This might be the perfect watch.
