9S85 description
Self-winding 'high-beat' movement with date. Caliber 9S85 features a t made of SEIKO’s proprietary alloy “SPRON530”. In addition, the balance spring is made of another recently developed highly shock resistant and anti-magnetic alloy “SPRON610” and the caliber uses a new escape wheel and pallet manufactured by MEMS. These new components contribute to its reliable and precise performance; its timekeeping precision is -3 to +5 seconds per day, a level that is confirmed in every case by testing to the very exacting Grand Seiko standard, the highest published standard in the industry.
