This Astron solar-powered timepiece is themed ‘Solidity,’ symbolising Seiko’s innovative spirit which has been present since the brand’s beginnings in 1881.

Under a sapphire crystal glass, and within a compact and slim bezel design, is a grey 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. The case is a compact and angular design that flows seamlessly from the bezel, through the lugs and to its bracelet. With sleek lines, this watch has a slim profile.

Powered by the in-house built 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.
