Seiko has officially locked in the release timing for its 145th anniversary limited-edition watch lineup. All four commemorative models are now confirmed to arrive in February 2026, giving collectors and Seiko fans a clear window to watch for availability.
This anniversary group spans four of Seiko’s best-known families: King Seiko, Presage, Prospex, and Astron. Each watch is positioned as a limited men’s release and is directly tied to the brand’s 145-year milestone, making February 2026 the key moment when the entire set is expected to hit the market.
Leading the most tradition-forward entry is the King Seiko SJE121. The watch takes clear inspiration from the historic KS1969 design language, leaning hard into heritage styling. Instead of chasing extra complications, it focuses on refined, smaller proportions and classic King Seiko character—exactly the kind of restrained approach that tends to appeal to enthusiasts who want vintage cues in a modern build. Seiko lists the SJE121 for a February 2026 release, in step with the rest of the anniversary models.
Next is a dressier option from the Presage lineup. The Presage Classic Series SPB538 is confirmed as a Seiko 145th Anniversary Limited Edition, with production capped at 1,450 pieces. Like the other three watches, it’s scheduled for February 2026 rather than being released separately, which suggests Seiko is treating this as a coordinated anniversary drop.
For buyers who want a sportier direction, Seiko is also bringing the Prospex Speedtimer SRQ059 into the anniversary mix. While details beyond timing and positioning haven’t been expanded here, Seiko has confirmed it as part of the same 145th anniversary limited-edition release wave, set for February 2026.
Rounding out the quartet is the Astron SSH186 from Seiko’s GPS Solar range. It, too, is confirmed as a Seiko 145th Anniversary Limited Edition and is limited to 1,450 units. Like the others, the SSH186 is scheduled to land in February 2026.
Instead of spacing these releases out across multiple months, Seiko appears to be concentrating its 145th anniversary rollout into a single, easy-to-track launch period. That’s good news for collectors who want to compare the models side by side—and especially for anyone aiming to secure more than one, or even the full set, without waiting through staggered release dates.
