Seiko’s reputation in the field of dive watches is hard to beat. While they may not have been behind the creation of the first dive watch, the contributions of Seiko in improving the concept of a timekeeping instrument for divers is immense. Many features that are now the norm for dive watches were created under the influence of Japanese engineers – Seiko even influenced the creation of the ISO 6425 standard for dive watches. So, with over 50 years of innovation, over 50 years creating professionally oriented watches… that’s half a century of know-how that has been infused in the watch that we’re reviewing today, the Seiko Prospex Marinemaster 1000m Automatic Diver SBDX014 a.k.a the “Emperor Tuna”.
