This product belongs to the historical collection of Seiko
The Astron World Time with 8x22 caliber movement is the slimmest watch from the exclusive Astron collection. As a result, the antenna that receives the GPS signals is of course much smaller than in the other models, but Seiko has ensured that the processing power of GPS module is increased, so that the sensitivity of the antenna is unchanged. Not only the technology is very advanced, the finish of the watch is also superior.
The construction of the dial is clear and simple as well as the operation. The crown contains an electronic setting function. A clear and hard coating is applied to the case and bracelet to prevent scratching. The glass is also coated with an anti-reflective layer, making the watch easy to read under every viewing angle.
