Seiko Unveils Limited-Edition Asia-Pacific Prospex Automatic Divers

Seiko has just expanded its highly coveted Prospex lineup with two striking new additions: the yellow-dialed HBB003 and the orange-dialed HBB004. Announced via Seiko India, these new automatic dive watches embrace a beautiful "coastal resort" theme. According to the brand, the vibrant colorways are designed to capture the atmospheric shift from a golden sunset to a tranquil night, making them a bold statement piece for any collector's wrist.

Underneath the colorful dials, both watches mean serious business. They feature a 41.7mm stainless-steel case that closely follows Seiko’s beloved, angular "Samurai" design language. Powered by the reliable 4R35 automatic caliber, the watches come equipped with a black rotating bezel and boast a dive-ready water resistance of 200 meters. Fans of the brand might also notice the unfamiliar "HBB" prefix—this is the result of Seiko overhauling its reference naming system in March 2026, moving away from the older patterns collectors are used to.

If you are looking to get your hands on one, you might need to act fast and be in the right region. Both the HBB003 and HBB004 are strictly limited to just 2,500 pieces each worldwide and are exclusive to the Asia-Pacific market (interestingly, excluding Japan). While official pricing has not yet been revealed, Seiko has teased that they will be "coming soon" to regional e-stores. For now, watch enthusiasts outside the Asia-Pacific region will have to keep their fingers crossed for a wider release.
