Seiko made it’s first diver’s watch in 1965. It was the beginning of a 50 year tradition at Seiko of advances in the security, legibility and durability of watches for diving in all conditions.  Seiko has been on the cutting edge for diver’s watches.  They created the first titanium case diver’s watch, the Professional Diver’s 600m.  They have been raising the level of security in the diver’s watches and the international standard for diver’s watches, ISO6425, was developed with Seiko’s own standard as its base.  Seiko diver’s watches are the world’s benchmark for excellence.
