Product Description

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.

The Evolution 9 Style is a set of original design techniques intended to further pursue usability and beauty in wristwatches and is a development upon the Grand Seiko Style. This sports watch combines these design elements with compliance with ISO standards to satisfy the requirements for a diver’s watch, with increased readability, operability, and robustness.

The coastal waters of Japan are influenced by the flow of the Kuroshio Current, one of the world’s major ocean currents, as well as by the nutrient-rich waters of the Oyashio Current, creating one of the world’s most diverse ocean regions. The dynamic undulation of the waves of these ocean currents is expressed in the powerful dial pattern of this watch, which also uses a unidirectionally rotating bezel with an insert made of ceramic. However, unlike last year’s Spring Drive diver’s watch, which was black, this year the dial and bezel are in Grand Seiko blue.
