Seiko Prospex SEA HBB001 – Limited dive watch for Seiko’s 145th anniversary

Sporty design with iconic Seiko blue

The Seiko Prospex SEA HBB001 was developed to celebrate Seiko’s 145th anniversary and combines the proven functionality of a Prospex dive watch with an exclusive anniversary design. The characteristic Seiko blue, which has defined the brand’s identity for decades, shapes the design of this limited special edition.

Blue accents on the bezel and seconds hand create a striking contrast to the silver-white dial and give the watch a modern, sporty-elegant appearance.

Robust construction for demanding use

The stainless steel case impresses with a clear, angular design language and high-quality workmanship. The precise shaping of the case surfaces creates a modern look and a strong presence on the wrist.

The solid stainless steel bracelet with finely crafted details perfectly complements the case and offers high wearing comfort as well as a secure fit.

Automatic movement with reliable performance

Inside works the proven Seiko caliber 4R35 with automatic winding and additional manual winding function. The power reserve of up to 41 hours ensures reliable performance in everyday life and while traveling.

Additionally, the movement features a date display and a hacking seconds function for precise time setting.

For adventures above and below water

As a true Prospex dive watch, the HBB001 offers water resistance up to 200 meters and is suitable for scuba diving. The unidirectional rotating bezel allows safe measurement of dive times.

LumiBrite on hands, indices, and bezel ensures excellent readability even in low light conditions or underwater.
