Everyday digital sports watch
The Casio F-91W-3SDG is a lightweight quartz watch with a square resin case and matching strap. A fixed bezel and buckle clasp keep the 37.50 mm profile secure on the wrist. It is built for daily wear and basic timing needs.
Simple strap fit for active use
The resin band fastens with a standard buckle, so no tools are needed to adjust the length. Water resistance to 30 m handles splashes and rain but not swimming. The slim case slides under a cuff without catching.
Steady quartz timing over long periods
The movement runs on a single battery and maintains consistent accuracy day after day. A 1/100 second stopwatch, daily alarm and auto calendar operate without drift. The micro light illuminates the display for quick checks in low light.
