With its accommodating 40mm diameter, this model combines presence and wearability with ease. The case embodies the contemporary Grand Seiko Style with its pleasing blend of hairline and mirror-polish finishing on top of an ergonomic design. The light silver sunray dial pairs perfectly with the strong three-dimensional indexes and bold handset, resulting in a highly legible watch even at a glance. Inside is Caliber 9S65, an automatic movement with manual winding capacity rated to +5 to-3 seconds a day. It features a power reserve of 72 hours, made possible through proprietary hairspring technology and an escapement made via MEMS.
