Casio Digital 38mm Unisex Watch

Ref. F-91WB-1AEF

The F-91WB-1AEF is a slim, lightweight variant of Casio's long-running F-91 series, built around a matte black resin case measuring 38.2 × 35.2 × 8.5 mm and weighing just 21 g. The dial is pared back with fewer mode indicators than the standard model, and the crystal is hard resin. The band is made from bio-based resin. The calibre 593 module offers a stopwatch accurate to 1/100 second, a daily alarm with hourly time signal, auto-calendar, and switchable 12/24-hour display. A faint green LED provides backlight. Battery life is approximately seven years.
