While faithful to the original designs, all three new watches offer upgraded specifications and execution. The greatest advance is in the grade of stainless steel used in the construction of the three watches. Known as Seiko’s “Ever-Brilliant Steel,” thanks to the brilliant white hue that gives
this trilogy of watches its unique look, this grade of steel is more corrosion resistant than that used in most of the highest-end watches today. * It will be used for the first time** in the watch industry for the cases of the 1965 and 1968 re-creations as well as the bezel of the 1975
re-creation, which, like the original, has a titanium case. This material has been used extensively in the surfaces, linings, bolts and other components of marine structures and vessels to avoid corrosion in a chloride-rich environment such as sea water. It poses many challenges in the
manufacture of watch cases but, thanks to the experience and innovative techniques of the Seiko team, Ever-Brilliant Steel is now set to bring a new level of durability to the diver’s watch.
