Evolution 9 Collection
RM45,400
Featuring the Evolution 9 Style, 200 meters of water resistance, and a blue variation on the “ushio” dial initially seen in 2022 in black, the new Reference SLGA023 is the latest diver’s watch from Grand Seiko. Below its distinctive, patterned dial is the Spring Drive Caliber 9RA5, a next-generation movement with automatic winding, ±10 seconds per month accuracy, and a power reserve of 120, or about five days, when fully wound.
