New Seiko Prospex limited edition watch on the way
Seiko Thailand has dropped a short teaser for what it calls the Prospex Muay Thai Limited Edition, with a full reveal set for November 26, 2025. The post doesn’t show much, but it does clarify that this release is tied directly to Thailand’s national combat sport.
The clip shows a Prospex diver sitting on what looks like the canvas of a boxing ring, surrounded by ropes and lit from above. The watch itself is almost completely in shadow, so there’s no look at dial colors, finishing, or any of the design choices that usually define these themed models. All you really see is the outline of a standard Seiko diver case, which means the final watch will stick to a familiar Prospex silhouette, as confirmed in the caption.
Seiko’s caption also mentions "heritage, respect, and fighting spirit," but doesn’t expand at all on how those elements will translate into the design. Past regional editions (like the Prospex Asia-Pacific editions) have used color accents, caseback engravings, and visual references rather than major changes to the watch itself. This teaser doesn’t confirm whether the Muay Thai edition will follow that pattern or try something a bit different.
What’s also unclear is how wide the release will be. Seiko Thailand often showcases Thailand-exclusive models that never make it to global retail, so this could end up being a regional piece. Nothing in the teaser hints at international availability.
For now, the only concrete details are the name of the edition and the reveal date. Everything else - specs, reference number, pricing, case material, and how deeply the Muay Thai theme is worked in - will drop once Seiko Thailand elaborates on the Instagram post on November 26.
