Seiko introduced two exciting limited-edition diver watches for the Asia-Pacific region in 2026 for only 2,500 pieces each model. These impressive models are the Seiko Prospex HBB003 and HBB004.
You can instantly recognize these timepieces due to their legendary Samurai design roots. Both timepieces embody a fresh design concept inspired by coastal resort atmospheres.
The overall concept captures the vivid shift from a golden sunset to a tranquil night. This coastal theme brings vibrant tropical energy directly onto your wrist.
Dial
The dial color defines the core identity of each specific model in this release. The Seiko Prospex HBB003 features a bright yellow dial that radiates bold energy.
This vivid yellow shade mirrors the radiant warmth of a brilliant tropical sun.
Meanwhile, the Seiko Prospex HBB004 showcases a rich orange dial with striking visual depth. This warm orange hue reflects the breathtaking glow of a dramatic ocean sunset.
Both dials showcase a finely textured surface pattern that catches light dynamically. The intricate grid texture adds fascinating depth and enhances readability under different lighting conditions.
Dark gray color framed hands and hour markers create sharp contrast against these bold background colors.
A black minute track circles the outer edge of the dial to ensure accurate time readings. A clean date display window rests neatly at the 4:30 o’clock position.
Seiko coats the hands, hour indices, and bezel markers with luminous LumiBrite material. This vibrant luminous coating guarantees excellent legibility in complete darkness or deep water.
Specification
Robust case construction ensures reliable performance under demanding marine environments. Seiko crafts the case entirely from durable stainless steel.
The case measures precisely 41.7mm in diameter. It features a sleek thickness of 12.3 mm for comfortable everyday wear.
The lug-to-lug distance measures 49.5mm across the wrist. Sharp lines and faceted geometric edges highlight the famous Samurai aesthetic.
A knurled texture on the crown provides excellent grip during manual adjustments. A scratch-resistant Hardlex glass covers and protects the textured dial from impacts.
These professional divers meet strict ISO standards for underwater exploration. Both models deliver a robust water resistance rating of 200 meters.
A black unidirectional rotating bezel allows divers to track elapsed underwater time accurately. The black bezel insert features clear minute markers for effortless tracking during dives.
A screw-down crown prevents water entry when diving beneath the surface. The solid screw caseback further enhances the protective integrity of the case structure.
A sturdy stainless steel bracelet secures the watch comfortably to the wearer’s wrist. The bracelet measures 20mm between the lugs for balanced overall proportions.
Seiko fits a 3-fold clasp featuring a secure lock and push-button release with extender. This integrated diver extender allows easy adjustment over a thick wetsuit sleeve.
Solid steel links provide substantial weight and comfortable balance on the wrist. Seiko proudly engraves the individual serial number on the steel case back.
The caseback also features an official limited edition stamp confirming its rarity.
Movement
The reliable automatic Caliber 4R35 movement powers both limited-edition timepieces. Watchmakers equip this mechanical caliber with 23 internal jewels for smooth operation.
The movement offers a power reserve of approximately 41 hours when fully wound. You can wind the watch manually or let the rotor wind it automatically.
A stop-second hand feature allows precise time setting down to the exact second. Magnetic resistance up to 4,800 A/m protects the internal movement from everyday magnetic fields.
Both Seiko Prospex HBB003 and HBB004 models are limited to 2,500 pieces and priced at AUD 995.
