Everyday Digital Watch for Casual Wear

The Casio F-91WM-2A is a lightweight unisex watch built for daily casual use. Its quartz movement keeps time reliably while the digital display shows the day and date at a glance. A built-in LED light makes the screen readable in low-light conditions.

Resin Construction with Fixed Bezel

The case, strap and crystal are all moulded from resin, giving a uniform feel that resists everyday knocks. A fixed bezel and buckle clasp keep the 35.00 mm case secure on the wrist without any moving bezel parts to catch on clothing. Water resistance is rated to 30 metres for splashes and brief immersion.

30 Metre Water Resistance Defines Limits

The 30 metre rating covers hand-washing, rain and accidental splashes but not swimming or showering. Buyers who need a watch for pool sessions or water sports should look for a higher depth rating. The daily alarm and hourly time signal add convenient reminders without requiring a smartphone link.

Questions about this item

What does the 30 m water-resistance rating cover in daily use?

It protects against splashes and brief immersion such as hand-washing or rain, but it is not suitable for swimming, diving or high-pressure water.

What are the case dimensions and strap material for fitting?

The resin case measures 35.00 mm thick and the matching resin strap uses a buckle clasp for adjustment.

How do I set the time and date on the F-91WM-2A, and which step is often missed?

Hold the adjust button until the seconds flash, cycle through hour, minute, year, month and day with the mode button, change each value with the forward button, then press adjust again to save — skipping the final press leaves the watch in setting mode.
