It’s hard to believe that only 4 years ago, Seiko launched it’s technological marvel, the Seiko Astron GPS Solar line of timepieces. Since it’s debut, Seiko has taken an evolutionary approach to the Astron lineup. Each year since its launch, Seiko has taken another step towards perfecting the Astron GPS Solar technology.
Following the initial 7X52 caliber, Seiko introduced the 8X chronograph caliber and dramatically altered the Astron landscape. Not only did this caliber add more features, it was also dramatically reduced in size while retaining its functionality. The size of the caliber and watches shrunk by 30% creating a much more wearable timepiece.
