Grand Seiko welcomes four new limited edition models that combine practicality and durability, the two vital attributes of all the best sports watches and are also core values of Grand Seiko.
All use Spring Drive GMT calibers and two feature chronographs. The materials and five-piece construction are designed for strength and lightness. The inner case is made from high-intensity titanium and the outer shells and bezel are zirconia ceramic which is stronger and tougher than any other fine ceramic and seven times harder on the Vickers scale than stainless steel. This combination of materials makes the case 25% lighter than stainless steel and virtually impervious to scratches. While the black color is new to Grand Seiko, the clear ridges on the facets of the case and the diamond-cut hands and markers make the watches instantly recognizable as Grand Seiko.
Since its creation in 1960, every Grand Seiko watch has demonstrated a consistent commitment to the pure essentials of watchmaking. Precision, legibility, comfort and durability are the attributes that have always defined Grand Seiko, and always will.
