Seiko’s Advanced Astron Collection Gets Four New References
If you like your watches complicated and your timezones varied, chances are you’re already aware of the Seiko Astron GPS Solar line, first launched in 2012.

Instead, its latest models use GPS technology and a solar-sensitive dial to automatically update the time according to your geographic position up to twice a day.

An imposing 44mm mirror-polished titanium case houses the Caliber 5X83 movement, which promises a litany of advanced features, most prominent of which is the aforementioned GPS-controlled time and time zone adjustment.

Of course, the titular chronographs also loom large on the dial, with a 1/20th second counter at 12 o’clock and a 12-hour counter with hours and minutes at 6 o’clock during chronograph operation...
