We’ve seen watches before that correct the time based on radio frequencies, but the problem with those is that they don’t work everywhere – with this Seiko, as long as you can see the sky you (or rather your watch) can work out what the correct time is, and display it. Oh, and add to this a solar charging system that charges the watches battery using any light source, you’ve got an watch that is seriously self reliant. Plus it’s a perpetual calendar.

The Seiko Astron has been released in a total of 6 different configurations, in stainless steel and titanium. It measures 47mm across, 16.5mm high, has a sapphire crystal (with super clear coating) and is water resistant to 100 meters. According to Seiko retail in Europe will be between 2000 and 3300 Euro.

To see the Astron in action (and the kind of person Seiko imagine buying this watch), check out this video from Seiko.
