The dial of SBGW285 is an expression of Byoka, the transition from summer to autumn. Because the summers in Iwate are short, signs of autumn are already felt in late August, when the surrounding greens are deeper than ever. 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, inspired by the first Grand Seiko from 1960, 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 an exhibition 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.
