Introducing the Seiko Astron in silvery white. Under a sapphire crystal glass, within a compact and slim bezel design, is a white-silver dial with a vertical hairline finish. The increased charging capacity of this calibre allows for a textured dial whilst still maintaining high charging efficiency. The titanium case construction has a super hard coating for increased scratch resistance. With sleek lines, this watch has a slim profile.
Powered by the 5X83 solar GPS calibre, which inherits the same functions of the 5X53, but it has the added capability to measure elapsed time through its chronograph feature. The chronograph can measure elapsed time up to 1/20th of a second. It is accurate to ± 15 seconds per month whilst having a power reserve of 6 months at full charge, and can be charged by any light source – either natural sunlight or artificial light – for convenience.
