Heavy and exceedingly well-made, many consider the SBGD001 the "holy grail" for Grand Seiko collectors. Powered by the incredibly well-finished Spring Drive movement, it is one of the finest creations made by Grand Seiko today. Every element, inside and out, is executed with excellence. The polished, bevelled edges of the movement bridges, or anglage, is incredibly well done - crisp, sharply defined, and mirror polished. Fitting, as the movement is finished by Micro Artist Studio. The textured dial is particularly beautiful, catching the light subtly. In fact, collectors have dubbed this effect “diamond dust”.

The platinum case is particularly heavy and impressive, giving the watch a stealth and understated appearance. Offered with its original certificate, it marks the first time the model appears on the international auction market.
