Seiko Astron Collection
Introducing this Solar GPS watch with a stainless steel bracelet strap, 41mm case with a blue coloured dial with date window.

Caliber 3X62
Each of the new watches is powered by a new GPS Solar movement, Caliber 3X62, whose enhanced reception of solar signals allowed for greater freedom in design. The watch connects automatically up to twice a day* to the GPS network to maintain its precision of one second every 100,000 years.

When the dial detects sunlight, the watch connects to the GPS satellite network and adjusts automatically to the correct time. If the watch is hidden from light, it remembers the time of its last successful manual connection and attempts to receive the GPS signal again at that same time.

A dynamic faceted bezel matching to the dimensional case
The new series has a dynamic presence thanks to the dimensional case and the faceted bezel with hairline finishing on top, which contrasts with the polished sides. The case lines flow seamlessly through the lugs to an integrated bracelet that has a sharp design that matches the angular case to give the watches a refined appearance. This bracelet tapers neatly toward the clasp, reinforcing its harmonious and graceful look.

Highly legible dial with a distinctive pattern
All four watches feature a dial with a simple design with a single sub-dial at 8 o’clock that indicates the receiving process of GPS satellites as well as the watch’s charging status, leap second data receipt, and in-flight mode. Matched to the color of the bezel, the applied indexes and the hour and minute hands, all filled with Lumibrite, enable easy reading in every viewing condition. The blue, grey, and black dials feature a pattern that evokes the quartz crystals used to create the tuning fork-shaped quartz oscillators of the original Quartz Astron introduced by Seiko in 1969. The Astron name, long associated with accuracy, has been carried on by the Astron GPS Solar series since 2012.

High visibility in low-light conditions
The indexes and the hour and minute hands of all the watches are all filled with Lumibrite, enhancing legibility in low-light conditions.

Comfortable on the wrist
The titanium case and bracelet have a scratch-resistant super-hard coating, and thanks to titanium’s light weight and the case’s low center of gravity, the watches sit comfortably on the wrist.
