Seiko has unveiled its third and final 145th-anniversary series, a six-watch menagerie built around what the brand calls “Edo purple.”
The color dates back to Japan’s Edo period (1603-1868), when Tokyo was still known as Edo, and it’s been treated as a signature regional shade ever since.
The lineup spans six different collections: a Prospex Alpinist ($900), a Prospex Speedtimer solar chronograph ($750), an Astron GPS Solar dual-time chronograph ($2,900), a Presage Cocktail Time GMT ($625), a Seiko 5 Sports SKX ($450), and a digital “Rotocall” revival under the Seiko Selection line ($585).
Every model gets gold-toned accents alongside its purple dial or strap detailing, with every case back getting a “LIMITED EDITION” engraving; production is capped between 2,000 and 9,999 pieces depending on the model.
Three color groups, one anniversary
First off, just my two cents, but I take the Rotocall version here — the design language is funky and the purple really pops. (Plus, you get some gold accents in there as well if you’re a Lakers fan).
Anniversary collections usually mean one flashy centerpiece watch and a big price tag to match. Seiko took the opposite approach this year, spreading the 145th-anniversary story across three separate color-coded drops instead: gold in January, “Seiko Blue” in May, and now purple to close it out.
It’s a smart way to stretch one milestone across an entire year without any single release feeling like an afterthought, and it also means there’s a price point in this specific purple wave for almost anyone — from the $450 5 Sports SKX up to the $2,900 titanium Astron.
This shade of purple is a genuine part of Japanese design history, the kind of reference that goes beyond “purple dial, neat” — which, if you’ve spent any time with the best Seiko watches on the market, tracks with how the brand usually operates.
Where to buy it
The Seiko 145th Anniversary “Edo Purple” collection arrives in October 2026 at Seiko Boutiques and select retailers, with pricing running from $450 for the 5 Sports SKX up to $2,900 for the Astron GPS Solar.
Given the tight production numbers on some of these — the Astron caps out at just 2,000 pieces — I’d keep an eye on release day if a specific model catches your attention.
