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.

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
HDB002
HDB002 puts a second time-zone display in a Seiko 5 Sports case measuring 39.4 mm across, 13.6 mm thick and 47.9 mm from lug to lug. The case length is 8.5 mm greater than its diameter, so both measurements belong in a size comparison. Its 4R34 automatic movement also supports hand winding and has an approximately 41-hour reserve. A 24-hour hand provides the second time display, alongside the date. Curved Hardlex covers the dial, and the movement is visible through the screw case back. Seiko lists 20 mm between the lugs and water resistance of 10 bar.
