Seiko is one of the largest and most revered watch brands on Earth, but its origin is as humble as can be. In 1881, after apprenticing since the age of 13, Kintaro Hattori opened his own watch and jewelry repair shop in Tokyo.

For the third release in its 145th-anniversary collection, Seiko honors the city it has always called home with a set of “Edo purple” dials. The blue-toned violet shade was prominent among the city’s merchant class during Japan’s Edo Period and remains associated with the city that became Tokyo.

As with the previous two 145th-anniversary releases, “Edo purple” dials are applied to watches that sample Seiko’s vast catalog. In this case, one of the brand’s most affordable and popular models was chosen: the Seiko 5 Sports SKX Series.

At $450, this purple automatic dive watch is more affordable than any previous 145th anniversary release. It is also the least “limited” of the nominally limited-edition references, with a whopping 9,999 units available.

Blocked off

Since Seiko revived the SKX line as part of the 5 Sports collection in 2019, it has produced far more references than I can keep track of. But of the new dial arrangement introduced in 2025, this is only the fifth example.

The new SKX design diverts from the cult-favorite 1990s dial by introducing a full set of rectangular indices, save for a trapezoidal 12:00 marker. Each is marked with a bulging off-white LumiBrite insert.

Another smaller augmentation is seen on the hour and minute hands, which lose their needle tips.

The “reverse lollipop” seconds hand is unchanged from the original SKX line, as is the day-date window at 3:00 and the minutes track printed on the rehaut.

Turning purple

The “Edo purple” dial looks a bit different on each of the four models in this release. For the 5 Sports SKX Series, Seiko applied the deepest, richest tone.

It also uses the same gold accent color, but sparingly applied to the logo and the stylized “Automatic” wordmark.

This “Edo purple” SKX Series is overshadowed by more impressive watches in Seiko’s trilogy of 145th anniversary releases, but viewed with the other four dive watches sporting the new SKX dial, it fits right in. The rich violet is a perfect addition to the blue, black, orange and yellow dials already forming the collection.

Availability and price

Seiko’s 145th Anniversary Seiko 5 Sports SKX Series “Edo purple” will be available in October 2026 for $450. As mentioned above, it is “limited” to 9,999 pieces, which means it should be readily available for a long time.
