Meet Seiko Astron, the world’s first GPS solar watch
It can be quite tedious to adjust your watch's time especially when you are flying to other parts of the world, and that you watch isn't digital. With this Seiko Astron GPS solar watch, you can get an accurate time no matter where you are on Earth.
Seiko, under the supervision of Seiko Epson Corporation, has developed a patented, low-energy-consumption GPS receiver and create a watch that can receive GPS signals and identify time zone, time and date data using the global network of GPS satellites. The Seiko Astron is solar-powered, and claims to be able to recognize all the 39 time zones on earth; the hands can adjust automatically to the correct local time with Atomic Clock precision. The watch also has a perpetual calendar such that the date will also be as accurate as the time. Simply press the button and the time and time zone will adjust automatically. It takes six seconds or a little more for the time to self-correct and 30 seconds or a little more for the time zone.
According to Seiko, there are three models in high-intensity titanium, which is stronger than stainless steel but 40% lighter, and two in stainless steel. But for such an advanced watch, the price doesn't come cheap. The recommended retail price for Seiko Astron is from 152,250 yen (US$1,880) to 210,000 yen (US$2,594).
