Inspired by a Japanese painting technique called Kira-zuri, true to its translation “sparkling painting”, the lustrous dial takes a life of its own. Commonly found in ukiyo-e paintings to create texture to the background of Kabuki actors, the inspired technique adds depth and excitement to the timepiece in movement and light. As with all Grand Seiko models, modern models pave their own path with their own unique characteristics, manufacturing methods and calibers, but in some way, always pay tribute to the past.
The gradient expressions of light and shadow found in Grand Seiko are based on Japanese aesthetic. Without one, there cannot be the other. The perfectly flat and mirror polished surfaces found on the case design of the 44GS create a sense of harmony between the light and shadow. This principle changed the standard of Grand Seiko design from 1967 forward.
A completely unique caliber, Spring Drive is powered solely by the motive force of a mainspring, as any luxury mechanical watch. What distinguishes it is its use of an exclusive escapement system using three different forms of energy (mechanical, electric, and electromagnetic) to regulate its precision. This mechanism, known as the Tri - Synchro Regulator, enables an astounding precision nearly unattainable by any other mechanical watch.
