Seiko Prospex Marinemaster SLA077
Ever since its first diver’s watch in 1965, Seiko has developed new technologies, features, and designs that have made its diver’s watches favorites among professional divers and adventurers the world over. In 1968, just three years after Seiko’s first diver’s watch was made, the brand’s engineers raised the bar by creating a high-beat diver’s watch with 300 meters of water resistance, laying one of the foundation stones on which future Seiko diver’s watch development would be based.
While the design reflects its heritage, every aspect of this new Marinemaster retains the traditions and high levels of diver's watch innovation upon which the Prospex collection was founded. The high-contrast design, with its precisely controlled color and texture of the dial and indexes, boasts outstanding legibility while bearing the traditions of Seiko's most sought-after divers, while new design elements, like the knurling found on the rotating bezel and crown have been improved for a better grip. To ensure the watch's durability, the crown is not screwed directly into the case but locked into a separate component that is built into the case so it can be more easily replaced.
The watch is finished with a high-transparency, dual-curved sapphire crystal with an anti-reflective coating on the inner surface to enhance legibility. High-intensity Lumibrite applied to the indexes and hands helps to increase safety and reduce stress when diving.
This Marinemaster is powered by Caliber 8L35 which was developed especially for diver's watches and is hand-assembled by the craftsmen and at the Shizukuishi Watch Studio in northern Japan. The movement's rigidity and accuracy ensure the highest possible levels of performance in the most demanding environments, both on land and under water.

History of Seiko Watches
Seiko's history began in 1881 when Kintaro Hattori opened a watch shop in Tokyo. In 1892, he established Seikosha, a factory for producing wall clocks. The company quickly progressed, creating Japan's first wristwatch, the Laurel, in 1913. Despite setbacks like the Great Kanto Earthquake of 1923, Seiko persevered, launching its first watch under the Seiko brand name in 1924.
The post-World War II era saw Seiko's rapid growth and innovation. They introduced Japan's first automatic wristwatch in 1956 and launched the prestigious Grand Seiko line in 1960. Seiko achieved international recognition for accuracy in 1968, winning a Geneva Observatory competition.
The company made a name for its divers in 1965 with the introduction of their first professional dive watch, the 62MAS. This was followed by the iconic 6159-7001 in 1968, which was water-resistant to 300 meters. Seiko gained international recognition in 1975 with the release of the 6159-7010, nicknamed the "Tuna Can" due to its distinctive case shape. In 1969, they revolutionized the industry with the Astron, the world's first quartz wristwatch, ushering a new era of watchmaking that would send waves across the industry through the 70s and 80s. From its humble beginnings to becoming a global watchmaking giant, Seiko's history is characterized by resilience, technological advancement, and a commitment to precision.
