About the Seiko Prospex

Prospex is Seiko's sports watch collection for activity at sea, on land and in the air. Its diving models continue a line that began in 1965, when Seiko made Japan's first diver's watch, and current references include heritage models based on Seiko divers from 1965 and 1968. The range is organised into series including Sea, Land, the Speedtimer chronographs inspired by a 1969 model, the Marinemaster, which Seiko calls its flagship series for diver's watches, and the LX line. The current line-up includes mechanical time-only, GMT and chronograph models.
