This limited-edition white 'high water' design celebrates Seiko's 100th Anniversary, drawing inspiration from the 1965 Japanese Diver's watch and the 2000s Marinemaster. The 1965 original marked Seiko's dive watch journey, known for its reliability on Antarctic expeditions. Despite the boxed sapphire glass, it's Seiko's slimmest mechanical diver. Powered by the 6L37 movement, it maintains strong accuracy and meets Seiko's Diving ISO standard. Limited to 1,000 pieces worldwide, it embodies Seiko Prospex, designed for practicality, reliability, and durability in extreme conditions. • Powered by the automatic movement with 26 jewels and a power reserve of up to 45 hours. • Presented on a silver stainless steel bracelet with push button deployment clasp. • Scratch resistant sapphire crystal glass. • 39.5mm case width. • 200 metre water resistance.
