This automatic watch is powered by Caliber 9S27, an automatic movement specifically designed for Grand Seiko’s women’s collection.

It has a mother of pearl dial in, of course, Grand Seiko blue and has diamonds as hour markers and which is framed on its bezel with 45 diamonds. After all, it is a diamond anniversary. Ref.
