Seiko expands its Astron GPS Solar watch collection by introducing new models in titanium.

This new series includes three regular production models with blue, grey or black dial, and a limited-edition watch with a unique, horizontally-striped design. Fusing dynamic and robust design, all four watches will be available at the Seiko Boutiques and select retail stores worldwide from July 2023.

Launched in 2012, the Seiko Astron GPS Solar watch connects to the Global Positioning System (GPS) and adjusts to every time zone while generating all the energy it needs from light alone. The brand has now expanded this range by introducing new models featuring a revamped design and equipped with the Caliber 3X62.

The newly released models have a case diameter of 41.2mm. The titanium case boasts a faceted bezel with hairline finishing on top, which contrasts with the polished sides. The integrated titanium bracelet has a sharp design that matches the angular case to give the watches a refined appearance. The titanium case and bracelet have a scratch-resistant super-hard coating.

The grey-dial version has a rose gold-colored super-hard coating on its bezel for a distinctive two-tone design.

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.

The applied indexes and the hour and minute hands are filled with Lumibrite. 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.

For the new watches, Seiko developed a new GPS Solar movement, Caliber 3X62. The watch connects automatically up to twice a day to the GPS network to maintain its precision of one second every 100,000 years.

The Astron GPS Solar Limited Edition watch (reference SSJ017) features the same design characteristics as the other three creations but has a dial with horizontal stripes in alternating shades of grey.
