SEIKO ASTRON HAB006J1 GPS SOLAR 2026 CHRONOGRAPH LIMITED EDITION MEN WATCH

The Seiko Astron HAB006J1 is a limited edition of 1,200 pieces worldwide, built on the newest GPS Solar platform and given a dial that has no equivalent in the standing range. Seiko calls the colour Crystal Pink, and the dial carries a newly developed pressed pattern of multiple facets meant to catch light the way a cut quartz crystal does. Against the black sub-dials, the pink reads warmer and considerably bolder than anything else the Astron line has carried.

Underneath is Calibre 5X63, the first Astron movement to run its chronograph out to 24 hours in 1/20-second increments with split-time capability, and the first to put the second time zone on a 24-hour sub-dial. The titanium case measures 43.4mm across, 50.0mm lug-to-lug and 12.4mm thick, with a two-piece octagonal bezel and a super-hard coating. It ships with the titanium bracelet and an additional black silicone strap in a special presentation box — and the quick-change system means swapping between them takes a button press.

Why You'll Love It

• Only 1,200 exist. This is a closed production run with a dial made for this edition alone — not a colour swap on a standing model.
• The Crystal Pink dial is the reason to want this one. A newly developed pressed pattern of multiple facets, drawn from the way light breaks across a quartz crystal, in a colour the Astron line has never carried before.
• Two watches in one box. The titanium bracelet and an additional black silicone strap are both included, and the quick-change system swaps them at the press of a button — formal on metal, sport on silicone, no tools.
• A 24-hour chronograph. Most stopwatches cap out at 12 hours, which means anything longer has to be tracked in your head. This one measures a full day in one go, with split times along the way.
• It sets itself. The watch connects to the GPS network to adjust its time and time zone, with a high-speed time zone adjustment and automatic daylight saving correction on top.
• Light alone runs it — approximately six months from a full charge, with a power save mode of around two years. No battery to replace.
• At 12.4mm, this is the slimmest case the Astron chronograph has worn, with a two-piece octagonal bezel designed to sit the weight low for better balance.
• Perpetual calendar to 2100 and a world time function covering 38 time zones — the date and day never need correcting, and the whole map is on the watch.

Key Features

• Limited edition of 1,200 pieces worldwide — a closed production run, supplied in a special presentation box with an additional silicone strap.
• Crystal Pink faceted dial — a newly developed pressed pattern of multiple facets inspired by the sparkling faces of a quartz crystal, in a pink made for this edition.
• Calibre 5X63 GPS Solar movement — the newest GPS Solar calibre in the Astron collection, combining dual-time capability with a 24-hour chronograph. Stated accuracy is ±15 seconds per month without a GPS signal, at temperatures between 5°C and 35°C.
• Chronograph up to 24 hours in 1/20-second increments — the 1/20-second counter sits at 9 o'clock, and the 24-hour counter (hours and minutes) runs at 6 o'clock during chronograph operation. Split-time capability lets you record an intermediate reading without stopping the count.
• Dual time on a 24-hour display — the second time zone is read in hours and minutes on a 24-hour sub-dial, so there is no separate AM/PM indicator to interpret. The main hands can also be set manually to a different zone.
• GPS time and time zone adjustment — with high-speed time zone adjustment, automatic daylight saving adjustment, a time transfer function to swap main dial and sub-dial readings, and a signal reception result indication.
• World time function covering 38 time zones, plus a perpetual calendar correct to the year 2100 and a power reserve indicator on the dial.
• Quick-change strap system — a button release on the case lets you swap between the supplied titanium bracelet and black silicone strap without tools.
• Titanium case and bracelet with super-hard coating — lighter than stainless steel, with a surface treatment that raises hardness against everyday scuffing.
• Two-piece octagonal titanium bezel — brushed on the top surface, polished down the faceted sides, and shaped to lower the centre of gravity for better balance on the wrist.
• Sapphire crystal with super-clear coating — the coating cuts reflections, and sapphire rates 9 on the Mohs hardness scale.
• LumiBrite on hands and markers, date and day-of-the-week displays, magnetic resistance of 4,800 A/m and 100-metre water resistance.
