Engineered for the serious diver and designed for the discerning collector, this automatic diver’s watch represents the pinnacle of Japanese precision, durability, and timeless style.

Whether you are exploring the ocean’s depths or commanding the boardroom, the Seiko Prospex HBC005J delivers uncompromising performance wrapped in a beautifully refined package.

The Movement

Driven by Seiko’s highly acclaimed Calibre 6R55 automatic movement, the HBC005J offers an exceptional 72 hours of power reserve — three full days of precision timekeeping without a single wind. With hand-winding capability, you are always in full control. Accurate to +25/-15 seconds per day at normal temperature ranges, this movement is as reliable as it is impressive.

The Dial

The bold white dial is engineered for maximum legibility both above and below the waterline. Hour, minute, and seconds hands are generously coated with Lumibrite — Seiko’s industry-leading luminous technology — alongside luminous markers, ensuring exceptional visibility in complete darkness and low-light diving conditions. A practical date function keeps you anchored to the real world, wherever your adventures take you.

The Case

Precision-crafted from polished and brushed stainless steel, the 40mm case with a 13mm profile sits perfectly on the wrist — substantial enough to command attention, refined enough for everyday wear. The screw-down crown provides an additional layer of water resistance protection, while the one-way rotating bezel allows accurate dive time tracking with absolute confidence. Protected by curved sapphire glass with an anti-reflective coating on the inside, the dial remains crystal clear and glare-free in all conditions.

The Performance

Rated to an extraordinary 300 metres water resistance, the Seiko Prospex HBC005J is built to handle the most demanding dive environments with ease. From recreational snorkelling to professional deep-sea diving, this timepiece exceeds expectations at every depth.

The Bracelet

The robust stainless steel bracelet in silver perfectly mirrors the case, delivering a seamless, integrated look that is as comfortable on the wrist as it is striking to the eye. Built to endure, built to impress.
