Contact our storesA crystal-inspired Astron Limited Edition
The Seiko Astron HAB009J1 is a GPS Solar 2026 Limited Edition inspired by the brilliance of crystals within dark rock. Its green dial and yellow-gold-coloured accents contrast with the black titanium case and bracelet. Mirror-polished centre links and a faceted bezel add a distinctive finish.
The light-powered 5X63 calibre uses GPS signals to adjust the time and time zone. Dual-Time, world time for 38 cities, a 24-hour chronograph and a perpetual calendar offer practical functions for travel and everyday wear. Sapphire crystal with Super-Clear coating and LumiBrite support clear legibility. The titanium bracelet features an easy-adjust folding clasp, while an additional calfskin strap with a quick-change system is included.
This model is limited to 1,500 pieces worldwide. The screw case back carries LIMITED EDITION and an individual serial number.

Frequently asked questions
Is an additional strap included?
Yes. An additional calfskin strap with a quick-change system is supplied alongside the black titanium bracelet.
How limited is this model?
This reference is limited to 1,500 pieces worldwide. The case back carries LIMITED EDITION and an individual serial number. The number shown in the product photograph is an example.
Is GPS Solar the same as an LTE smartwatch?
No. GPS is used here for time and time-zone adjustment, not calls or mobile data. The watch is powered by light. To change time zones, start the time-zone adjustment with a clear view of the sky; the watch does not continuously follow changes in your location.
Can I swim with it?
The watch is water resistant to 10 bar (100 metres) and suitable for swimming. It is not a scuba-diving watch; 100 metres is not a permitted diving depth. Do not operate the crown or buttons when the watch is wet, and keep the leather strap out of water.
