Product description

This special automatic GMT watch bears the name 'Keshizumi', which means charcoal grey. The SPB275J1 is part of the Seiko Presage Sharp Edged collection. A special series of watches designed with sleek angles and surfaces in different polishes like a classic samurai sword. The dial contains a three-dimensional 'Asanoha' (hemp leaf) pattern that traditionally represents growth, health and prosperity. The rich texture and sharp angles of the watch and dial create exciting color gradations that give the watch a new look every time the light hits the watch. The case and strap have a super-hard coating that protects the watch from scratches and gives it a long-lasting silky shine. The automatic and manual 6R34 movement combined with the GMT hand and highly visible hour markers and clear 24-hour bezel ensure that multiple time zone calculations can be made quickly and easily at a glance.
