Grand Seiko Evolution 9 SLGA015

Royal Jewelers is an authorized Grand Seiko dealer in the Boston area and offers the Grand Seiko Evolution 9 SLGA015 with Grand Seiko's 5 year warranty.

SLGA015's case is rendered in High-Intensity Titanium, and it measures 43.8mm in diameter, 13.8mm in thickness, and 51.5mm lug-to-lug. It is water-resistant to a depth of 200 meters and has a magnetic resistance of 4,800 A/m.

The case features a mix of Zaratsu-polished and hairline surfaces. The bracelet has a five-link design, and the three-fold clasp is fitted with a secure lock and diver’s extension.

The dial is deep black, and it is inspired by the Kuroshio Current, also known as the Black Stream. Each hand on SLGA015 is different in design and stands out clearly from the dial, and the double index at twelve o’clock ensures readability. Nighttime visibility is achieved through LumiBrite on the titanium hands and indexes.

Powering the watch is 9RA5, a next-generation Spring Drive movement. 9RA5 is made slimmer, more structurally robust, and more accurate with a rating of ±10 seconds per month and a power reserve of five days.
