Classic Digital Watch for Everyday Use

The Casio F-91WM-3A is a lightweight quartz watch built with a resin case and strap for daily comfort. Its square digital display shows the time, day and date at a glance. A buckle clasp keeps the band secure on the wrist.

38.00 mm Case with Core Timekeeping Functions

The compact case fits easily under a sleeve and offers splash resistance for hand-washing or light rain. Features include a 1/100 second stopwatch, a daily alarm and an LED light for low-light reading. It is not suited for swimming or diving.

Replaces Basic Analog or Worn Digital Models

The jump is worth it when you want a single watch that combines stopwatch, alarm and calendar functions without a smartphone. Buyers who need water resistance for swimming, a metal bracelet or solar charging should look elsewhere.

Questions about this item

Will the 38.00 mm resin case fit comfortably under the cuff of a shirt I already wear?

The 38.00 mm square resin case is slim and light, so it slides easily under most shirt cuffs without catching.

How can I confirm the LED light and 1/100 second stopwatch are working correctly after I put the watch on?

Press the light button to see the display illuminate, then start the stopwatch and verify the hundredths-of-a-second digits advance smoothly.

Does the box include the resin strap with buckle clasp and mineral crystal already fitted, or must I buy them separately?

The watch ships complete with the resin strap, buckle clasp and mineral crystal installed; no extra parts are needed.
