Compact Digital Watch for Everyday Use

The Casio LA-20WH-1A is a compact digital watch with a 34.5 × 30.4 × 8.6 mm stainless steel case and black resin band. It weighs 16 g and offers 30 m water resistance. A 1/100-second stopwatch, daily alarm, hourly time signal, auto-calendar with 28-day February and LED light cover essential timekeeping. The CR1616 battery lasts approximately 5 years.

Suited for Minimalist Daily Wear

This watch suits adults wanting a lightweight, unisex accessory for casual daily use. The adjustable resin strap fits smaller wrists comfortably. Buyers who need a heart-rate monitor, GPS tracking or smartphone notifications should look at dedicated fitness or smart watches. The 30 m rating only covers splashes and brief immersion, so swimmers and divers need higher water resistance.

Steady Operation Over Years

Quartz movement keeps consistent accuracy without winding. The LED light provides on-demand illumination rather than a constant glow, preserving the CR1616 cell for its full 5-year span. Stopwatch, alarm and hourly signal draw negligible power during regular daily activation. The resin band and stainless steel case resist sweat and minor impacts during sustained everyday wear.

Questions about this item

What wrist size does the 34.5 mm case and adjustable resin band fit?

The case measures 34.5 × 30.4 × 8.6 mm and the band is resizable, so it suits smaller wrists and can be adjusted for a secure fit.

Will the 30 m water resistance survive the same splashes my old analogue watch handled?

Yes, 30 m water resistance covers everyday splashes, rain and hand-washing, matching the protection of most traditional daily-wear watches.

How do I confirm the stopwatch and alarm are working after I set the time?

Press the mode button to reach the 1/100-second stopwatch, start it and watch the digits count; then set the daily alarm and wait for it to sound at the chosen hour.
