Just as SEIKO's introduction of the world's first quartz watch back in 1969, the unveiling of its Astron GPS Solar timepiece at this week's BASELWORLD transforms the world of horology once again. With its own Caliber 7X52 movement and encased in titanium, there are no remarkable differences between the SEIKO Astron GPS Solar watch and many of its contemporaries. The truly unique aspect, however, is the Astron's ability to adjust time accurately and automatically to whatever timezone its in. While such watch already exist on the market, the Astron will be the first to utilize orbiting GPS satellites instead of radio transmission towers. There are several immediate advantages, including limitless range and the inclusion of all 39 timezones around the globe. To activate the automatic calibration, simple push a button and the high-tech system will do the rest. In fact, with its perpetual calendar accurate to the year 2100 and a solar power unit that functions in any forms of light source, the SEIKO Astron GPS Solar watch is taking a first step in a brand horology category. Prices ranging from US$1,900 to $2,600, the SEIKO Astron GPS Solar will be available at select dealers later this year.
