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.

Where to buy
No retailer listing has been matched to a version on this line yet.
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.

| “Arnie” | Collector nickname. Source names SNJ029, SNJ031. “In tan (SNJ029) and drab green (SNJ031) versions, this Arnie has a particularly military inspired vibe to it.” | Worn & Wound read 2026-11-12 |

| “Safarnie” | Collector nickname. Source names SNJ029, SNJ031. “The resulting Seiko Prospex SNJ029 and Seiko Prospex SNJ031 have already been christened “Safarnie” by the Seiko faithful, channeling the best of the original Seiko H558’s jungle-fighting associations while adding a colorful new punch.” | aBlogtoWatch read 2026-11-12 |
