Product Details

Description

The Seiko HBC005J1 is an exclusive men's automatic watch from the Prospex Sea collection, released as a Limited Edition of just 4,000 pieces worldwide to celebrate Seiko's 145th anniversary. The case design pays homage to Japan's first diver's watch from 1965, blending iconic style with modern precision. The distinctive blue bezel insert, inspired by the legendary "Seiko Blue" established in the 1960s, harmonises perfectly with the silver-white dial, lending the watch a fresh and elegant presence on the wrist.

The stainless steel case, measuring 40mm in diameter and 13mm in thickness, houses Seiko's in-house automatic movement Calibre 6R55 with manual winding capability and a power reserve of approximately 72 hours. The domed sapphire crystal with inner anti-reflective coating, combined with LumiBrite luminous material on the hands, indices and bezel, ensures excellent legibility even in challenging light conditions. With water resistance to 300 metres, this watch is a reliable companion for ambitious divers.
