In 1968, just three years after Seiko’s first diver’s watch was made,
Seiko’s engineers raised the bar with a hi-beat diver’s watch with
300 metre water resistance, which became one of the foundation
stones on which Seiko’s future diver’s watch development was
based. It had a 10-beat high precision automatic calibre, a onepiece
structure, screw-down protection crown and unidirectional
rotating bezel. 50 years after, Seiko presents a commemorative
version of this watch.

Its signature feature is the deep green colour
of the dial and bezel. Durability and strength are the watchwords;
the zirconia ceramic bezel is highly resistant to scratches
and shocks, the stainless steel case has a super-hard coating
and the sapphire crystal has an anti-reflective coating both inside
and out. The minute markers on the bezel are painted with
a specially powerful Lumibrite to increase the legibility of the
rotating bezel. In addition to the steel bracelet, a high strength
silicone strap also accompanies the watch
