In 1986, Seiko launched a diver's watch that set a new standard. It combined Seiko's legendary 1975 design with a 1,000 meter water resistance for saturation diving with a quartz movement that delivered an accuracy that no mechanical diver's watch could match. At the time, and still today, it was recognized as one of Seiko's most important diver's watches. Today, 35 years later, this classic Seiko Diver's watch is re-born with new design features and upgraded professional diver's watch specifications. This is a watch that truly lives up to the promise of the Prospex name.
