Seiko introduced its first diver’s watch in 1965. In the decades since, the company has developed new technologies, designs, and features that have made its collection of Seiko Prospex diver’s watches a favorite among professionals and enthusiasts the world over. Continuous innovation and enhancements in safety, reliability, and ease of use have made Seiko a leader in the category. The Marinemaster is Seiko’s flagship series for diving, equipped with a robust and high-performance movement with stable accuracy designed exclusively for diver’s watches. It represents the top tier of Prospex watches in a diving category that is integral to the history and culture of Seiko. Originally launched in the Japanese domestic market, the series has been revitalized and makes its global debut with three new Prospex Marinemaster creations – one limited edition and two mainline introductions.
