Casio MQ-24-1ELDF analogue watch

The Casio MQ-24-1ELDF is a lightweight analogue wristwatch with a black dial and index markers. Its resin case and matching strap keep the profile slim and comfortable for everyday casual wear. Quartz movement calibrated to the SR621SW caliber delivers a rated accuracy of ±20 seconds per month. The 34.90 mm case diameter suits wrists that prefer a compact, understated presence.

Check strap length and water rating before ordering

The resin band fastens with a buckle clasp; verify that the maximum circumference fits your wrist without needing extra links. Water resistance is rated at 30 metres, which covers splashes and brief immersion but not swimming or showering. The fixed bezel and snap-down case back are not user-serviceable, so battery changes require a watchmaker. Ensure the analog display format matches your reading preference.

Steady daily timekeeping within quoted tolerance

Under continuous wear the quartz module maintains the stated ±20 seconds per month deviation without the drift seen in mechanical movements. Temperature swings typical of indoor and outdoor environments do not cause sudden rate changes. The SR621SW cell provides multi-year runtime, so the movement runs uninterrupted between battery swaps. No winding or motion is needed to sustain operation.

Questions about this item

What items are included with the Casio MQ-24-1ELDF watch, and is anything else needed to start using it?

The watch ships complete with its resin case, resin strap and buckle clasp already fitted. A SR621SW battery is pre-installed at the factory, so no separate purchase is required before wearing it.

How should I decide between the available versions of the MQ-24-1ELDF?

Only one specification is offered: a 34.90 mm round resin case with a black analog dial and 30 m water resistance. There are no alternative case sizes, dial colours or strap options to choose from.

What does the stated accuracy of ±20 seconds per month mean for everyday timekeeping?

The quartz movement is calibrated to stay within twenty seconds of the correct time over a thirty-day period. In practice the watch will typically drift only a few seconds each week, so occasional adjustment keeps it precise.
