A Top-Quality 3-Day Automatic Watch for an Active Lifestyle
With an upgraded Caliber 9S55 mechanical movement, this watch typifies the standard of high quality in the Grand Seiko collection.
The watch boasts a maximum 3-day power reserve and combines the latest in hairspring technology with an escapement (escape wheel and pallet) developed through Seiko's MEMS technology to achieve high accuracy and stability when worn.
The exterior sets it apart from other Grand Seiko watches, with a bold design to catch the attention of onlookers.
The boldness of the crown guard and lugs is preserved as the dial has changed from a light steel blue to white, producing an active and refined elegance in the watch face.
The case's mirror finish produces a lustrous shine achieved through multi-faceted Zaratsu polishing.
One can enjoy watching the mechanical movement exquisitely mark out the time through the transparent case back.
This model pushes the performance and quality of both the movement and the exterior to the limit, and brings an added flair to an active outfit.
