The reference high-end quartz.
Grand Seiko SBGV245: Cal. 9F62 thermocompensated quartz, ±10 sec/year, twin-pulse stepper motor, hand-finished case + dial. The benchmark.
Quartz is not just for the supermarket
High-end quartz is a distinct genre. Grand Seiko's 9F caliber (1993) hits ±10 sec/year through thermocompensation; Citizen's Calibre 0100 (2019) hits ±1 sec/year. These are watches that beat mechanical chronometers by orders of magnitude on accuracy.
Beyond accuracy: zero servicing, zero winding, multi-year battery life, and case-build quality matching mechanical luxury references. The under-€500 quartz picks earn their slots through reliability, not finishing.
