In 1969, Seiko introduced the first quartz watch, and now they are introducing the world’s first solar GPS watch. Using their own, patented, low-energy-consumption GPS receiver, the Astron is able to recognize all 39 time zones around the world to identify time zone and set the time and date data using the global network of GPS satellites. The Astron receives the time signal once a day, and it can connect to at least four GPS satellites on command to determine the time zone and the exact time. There are five models in the Astron line: three in “high-intensity titanium, which is stronger than stainless steel but has only 60% of its weight, and two in stainless steel. All have ceramic bezels, the same functions and high specifications, including a dual time sub-dial, in-flight mode indicator and sapphire crystal with Super-Clear Coating.” All have ceramic faces and all have the same functions, and they’re solar-powered so you don’t need to worry with batteries. The Astron will be available in Autumn 2012; no price information is available yet. Read the full press release at the Astron link above.
