Seiko is known for creating a legendary and exquisite range of watches especially for adventurers, professionals, sports enthusiasts, and everyone in between.
In 1965, Seiko introduced their most innovative diver’s watch that many divers across the globe dearly loved. This has become the global standard as a result of 50 years of innovation.
It all started when Seiko received a letter from a diver who explained how all their watches got damaged when using a diving capsule in the depths greater than 300 meters. Seiko then spent years of development and the world’s first ever Professional Diver’s 600m with titanium case came to fruition.
Their early creations laid the groundwork for Seiko to continue to revolutionize, modernize, and perfect diving watches.
With their relentless passion to create more advanced diver watches, Seiko has released the evolution of the Marine Master range under their Prospex line. Another iconic timepiece series that absolutely keeps up with any diver’s professional needs and lifestyle.
Seiko Prospex challenges every limit. The design is impeccable, stylish, classic, rugged, and absolutely luxurious.
At Watch Outz, we are as passionate and enthusiastic as you when it comes to the exquisite and world class Japanese watches. Ergo, we reviewed and compared three of the most special Seiko Prospex Marine Master diver watches just for you.
