What is Prospex?

Prospex is the line of rugged, water-ready sports watches from the Japanese watchmaker Seiko. It groups the company's professional specification models, above all its diver's watches.

History

The line draws on Seiko's diving history, which began in 1965 with the 150m Diver's watch known as the 62MAS, featuring a screw-down crown, a readable bezel and luminous markers. Later milestones that Prospex reissues and reinterprets include:

  • The Professional Diver 600m of 1975, with its titanium case nicknamed the tuna can
  • Seiko's first 1000m diver in 1986
  • A 1970s diver worn in the film Apocalypse Now
  • The H558 multifunction watch with alarm and chronograph

Products and positioning

Prospex covers automatic, quartz and solar models, from accessible divers such as the SRP777, nicknamed the Turtle, to limited editions with high-end movements. Recreations of historic models sit alongside modern designs such as solar-powered hybrids.

Distribution

Prospex watches are sold through Seiko's boutiques and website as well as authorised jewellers and watch retailers worldwide.

Why it matters

Prospex is central to Seiko's sports watch identity and to the global reputation of Japanese dive watches, combining technical heritage with accessible prices for enthusiasts.
