Seiko Prospex Sea HBB003K Limited Edition Automatic Diver’s Watch

Seiko Prospex Sea HBB003K Limited Edition Automatic Diver’s Watch

3 Year Manufactures Warranty

Make a bold statement with the Seiko Prospex HBB003K, an Asia Exclusive Limited Edition automatic diver’s watch combining professional-level functionality with a striking yellow dial.

Produced in a strictly limited run of just 2,500 individually numbered pieces, the HBB003K is an impressive addition to Seiko’s renowned Prospex Sea collection. Its vibrant yellow dial provides a distinctive contrast against the silver-tone stainless steel case and bracelet, creating a sporty, highly recognisable look.

At the heart of the watch is Seiko’s dependable Calibre 4R35 automatic movement. Powered naturally by the movement of the wearer, it also offers hand-winding capability and provides an approximate 41-hour power reserve. The traditional three-hand analogue display is complemented by a practical date window for everyday wear.

Built with serious diving performance in mind, the HBB003K offers 200 metres diver’s water resistance, a screw-down crown and a one-way rotating timing bezel. Seiko LumiBrite is applied to the hands and hour markers to provide enhanced visibility in dark and low-light environments.

The substantial 41.7mm stainless steel case is paired with a matching stainless steel bracelet, giving the watch a solid yet versatile presence on the wrist. Hardlex glass protects the dial, while the case measures 12.3mm thick with a 49.5mm overall length and 20mm lug width.

As an Asia Exclusive Limited Edition, each HBB003K is individually numbered and supplied in a special presentation box, adding further collectability to this distinctive Prospex diver.

A superb choice for Seiko collectors, diving-watch enthusiasts or anyone looking for a rugged automatic sports watch with a colourway that stands apart from the crowd.
