Casio LA20WH-4A1 Digital Watch

The Casio LA20WH-4A1 is a casual digital wristwatch designed for adult women. It features a square resin case measuring 30.40 mm in thickness with a black dial and matching resin strap. The quartz movement powers a digital display showing day and date, secured by a mineral crystal and buckle clasp. Splash resistance protects against light moisture exposure.

Everyday wear for casual style

This watch suits buyers wanting a simple, lightweight accessory for daily use with basic time and calendar functions. The resin construction and adjustable strap offer comfort for informal settings. It is not for buyers who need swim-rated water resistance, advanced sports timers, smartwatch connectivity, or a metal bracelet and sapphire crystal.

Core functions covered, extras absent

The digital module handles timekeeping, day and date readouts, and a chronograph function for basic interval timing. The 30.40 mm case depth provides a slim profile on the wrist. Headroom ends at splash resistance, so submersion, diving, or high-pressure water jets are not supported. No alarms, world timers, or backlight specifications are detailed in the supplied data.

Questions about this item

Does the 30.40 mm resin case need a specific lug-width strap if I replace the original band?

The integrated resin strap uses a buckle clasp and is resizable; no separate lug-width measurement is given for aftermarket bands.

Can the quartz movement run alongside a mechanical watch on the same winder?

The watch is battery-powered quartz, so it does not require a mechanical winder and will not interact with one.

How can I confirm the day and date display is advancing correctly after setting it?

Advance the time past midnight and verify the day and date change together on the digital display.
