Seiko Astron Watches

Seiko Astron GPS solar - the watch that adjusts to all the time zones on earth  The watch receives a radio controlled signal from satellites orbiting the earth even on the move - whenever the wearer is outside and can see the sky the signal is picked up ensuring you can tell the exact local time.  Astron gathers all the power that is needed from light absorbed through the glass front.  It uses all forms of light and stores the power for later.  Accurate to one second in 100,000 years as the watch is linked to the atomic clock in each GPS satellite.  Includes a perpetual calendar (correct until 28/2/2100) - no need to adjust the date when there are less than 31 days in the month, it just happens automatically.

Models available include titanium, stainless steel and the limited edition Novak Djokovic.  Additional features include sapphire glass with anti-reflective coating, daylight saving time adjustment, power save, 100M (10bar) water resistant
