SEIKO Astron 3X 'Sun' Men's SSJ026J1

Seiko Astron: the world's first GPS solar watch - it draws energy from light and adapts to the exact time of your destination via GPS technology. This model is called "Solidity" because of its robust design and is powered by the 5X movement. To improve the speed and quality of the GPS connection, Seiko has redesigned every component of the 5X movement. This allows it to adjust within 3 seconds even if it needs to move 14 time zones forward, thanks to the independent movement of the hour, minute and seconds hands.
