The Second Revolution:
- In 1969, Seiko released the world's first quartz wristwatch, the original Astron, and changed the course of watchmaking forever. The name came from the Greek word for stars and space, chosen because Seiko believed precision belonged to everyone. Over fifty years later, Seiko brought the name back for what it called a second revolution: the world's first GPS Solar watch. The SSH151J1 is the direct descendant of both of those moments.
- It connects to the same GPS satellite constellation that guides aircraft and ships. When the dial sees daylight, it reaches up, finds what it needs, and corrects itself, automatically, silently, to the exact second. You don't ask it to. It just does.
Built Without Compromise:
- The case and bracelet are titanium with a super-hard coating, lighter than steel, tougher than it looks, and hypoallergenic for those with sensitive skin. Satellites, solar cells, a perpetual calendar, and it feels like wearing air.
- The dial is a deep night black with a dark blue undertone that emerges beneath certain light, the solar cell beneath the surface doing something most watchmakers would hide. Seiko made it part of the character of the watch.
- The sapphire crystal carries an anti-reflective coating on both sides, creating an effect owners consistently describe the same way: you look down at the dial and wonder where the glass went. You're not looking through a watch. You're looking at one.
- LumiBrite on the hands and indices ensures the watch reads clearly in complete darkness, from any angle.
The Luxury of Never Having to Think About It:
- Some watches demand your attention. This one just asks to be worn. No winding. No setting the time. No date corrections. No AM/PM confusion after a long weekend. Leave it in a drawer for two weeks, pick it up, put it on and go, it's exactly right. It has been the whole time.
- Powered by Seiko's in-house 5X63 Solar GPS calibre, the watch charges from any light source and carries a power reserve of approximately six months on a full charge. Routine battery changes are a thing of the past.
- Travel anywhere in the world, press a button, and the hands move to local time, automatically accounting for your time zone and daylight saving. An in-flight mode disables GPS reception while airborne. The perpetual calendar runs itself until 28 February 2100.
- The micro-adjustable clasp with push-button release allows on-the-fly bracelet sizing without tools. It's the detail nobody expects to care about. Ask any owner.
Why Collectors Choose It:
- This is the watch that earns its attention on its own terms. Collectors who own watches costing considerably more describe the Astron as the one they keep reaching for, not because it's the most impressive thing they own, but because it's the easiest one to love.
- The dial has a way of being noticed by people who don't notice watches. The depth of it, the way it shifts between black and blue, the indices catching light from angles photography never quite captures. Owners talk about noticing new things in it months after buying.
- 100 metres water resistant. Allergy-safe metal. 3 years manufacturer warranty. World time across 39 time zones. This is high technology worn lightly, in every sense of the word.
