Three Seiko diver’s watches that made history: 1968 Hi-beat Diver’s 300m, 1965 62MAS 150m, and 1975 Professional Diver’s 600m.
This SBDX035 has a titanium one-piece case and an outer case protector as same as the 1975 original. The case construction and dial layout are loyal to the original, as are the unique hour markers and the crown, while the water resistance has been increased to 1,000m. The outer case material is zirconia ceramic, seven times harder than steel protecting the case from shock.
Since this is a reissue model of the original Seiko Diver, it keeps all the innovations that Seiko brought to diver's watches in the 1970s, including the double-layer construction with the one-piece inner case, the L-shaped gasket for helium resistance and the accordion-style strap.
