Classic Digital Watch

The Casio F91WM-7A is a lightweight resin watch with a 30mm square case and digital display. Its silver-tone finish updates the classic F-91W design for daily wear. Unisex styling and an adjustable resin band with buckle clasp suit a wide range of wrist sizes.

Build Integration

The 38.2 × 35.2 × 8.5 mm case sits flat and unobtrusive under shirt cuffs. Quartz movement powered by a CR2016 cell removes the need for winding or charging. Fixed bezel and 37.00 mm case thickness keep the profile simple for layering with other accessories.

Capacity and Headroom

A 1/100-second stopwatch, daily alarm, hourly signal and auto-calendar running to 2099 cover core timekeeping needs. The 7-year battery life reduces maintenance to a minimum. Water resistance handles splashes and brief immersion but is not suited for swimming or diving.
