Listed means the watch was on an official Seiko regional site or store at the last check. It does not mean it is in stock, and it does not tell us whether Seiko is still making it.

Versions listed now

Same case and movement in every row. What changes is the colour, the strap or bracelet, the finish and where Seiko sells it. Seiko's spec sheets don't state dial colour, so a colour appears only where Seiko's US store tags one.

Estimated US prices use Seiko's US list price where there is one. Otherwise they are the middle of Seiko's list prices in other countries, converted at rates dated Nov 12, 2026 from ExchangeRate-API (free open endpoint). Those list prices include each country's sales tax, so a converted figure usually runs higher than a US price would. Retailer prices are asking prices on the date shown, not sold prices, and leave out shipping, tax and import charges.

Research notes

HAB001

HAB001 is an Astron GPS solar chronograph powered by caliber 5X63. It combines a second time display, world time for 38 cities and a stopwatch measuring up to 24 hours in twentieth-second steps. GPS reception supports time-zone adjustment and automatic or manual time correction. Seiko specifies about six months of operation from a full charge, or about two years in power-save mode. The coated titanium case measures 43.4 mm in diameter, 12.4 mm thick and 50.0 mm from lug to lug. Sapphire covers the dial. The bracelet has a quick-change system, while the published lug spacing is 14 mm and water resistance is 10 bar.
