SBGW283 expresses Kishun, the transition of seasons from spring to summer. The light blue color of the dial is inspired by the gentle breeze and the skies specific to this season in Shizukuishi, Iwate Prefecture, where Grand Seiko mechanical watches are produced. The watch features razor-sharp hour and minute dauphine hands, and faceted polished indexes mark every hour position. The interplay of light and shadow, synonymous with Grand Seiko design, is on full display from the dial to the case.
The case is inspired by the first Grand Seiko from 1960. It measures 37.3mm in diameter, 11.6mm in thickness, and 44.3mm in length. The hard-wearing box-shape sapphire crystal captures the desirable look of vintage acrylic crystals without any of the shortcomings.
Visible through the case back is caliber 9S64, a mechanical manual-wind movement with 72 hours of power reserve and an accuracy rating of -3 to +5 seconds per day.
