Magnetic resistance 4,800A/m. Screwdown caseback. Caliber 8X22. Black Ceramic Bezel. Titanium Case with rose gold coating Caliber 8X22 is a notable advancement in Seiko’s GPS Solar technology. The case is slimmer than any other GPS Solar watch1, including all other Astron models (the depth is 12.4mm compared to 13.3mm in the original 8X series). As a result, the antenna that receives the GPS signals is smaller, designed with increased processing power of the circuit in the GPS module so that the sensitivity of the antenna is unchanged and the reception of GPS signals is easy for the world traveler. With just one touch of a button, the new Astron adjusts to the local time in every time zone2 of the world, with an accuracy of one second every 100,000 years, using the power of light. The dial of the new World-Time watch is simple, with all the indicators in one small sub-dial, giving the watch a quiet, refined elegance. The Astron GPS Solar World-Time offers everything essential — truly, less is more.
