Casio MQ-24B-8B Bio-Based Resin Watch

The Casio MQ-24B-8B is a unisex analog quartz watch built with a resin case and a bio-based resin strap. Its black dial features numeric markers for clear time reading at a glance. The watch measures 34.90 mm in thickness and uses a buckle clasp for secure fastening. It suits wearers who want a simple, lightweight daily accessory.

Upgrade from basic digital or plastic-strap watches

This model replaces entry-level digital watches or older resin-band analogues that lack a bio-based strap. The jump is worth it when you prefer an analog display with numeric markers and a more sustainable band material. Buyers who need advanced functions such as alarms, chronographs or smartphone connectivity will not find them here.

Simple strap adjustment and battery access

The resin strap can be trimmed with standard tools to fit most wrist sizes, and the buckle clasp locks with a single press. A snap-on case back allows a watchmaker to swap the coin cell without special equipment. The resin crystal resists everyday knocks but will scratch if dragged across abrasive surfaces. Splash resistance covers rain and hand-washing only; do not submerge or press buttons while wet.

Questions about this item

What case thickness must my wrist accommodate for the 34.90 mm resin case?

The case measures 34.90 mm thick, so ensure your wrist can fit a watch of that profile before purchase.

How do I set the time on the quartz movement, and what step do people often miss?

Pull the crown out to the setting position, turn to adjust the hands, then push the crown fully back in to restart the quartz movement.

When should I replace the bio-based resin strap or the buckle clasp?

Replace the strap if it shows cracks, stiffness or discolouration, and replace the buckle clasp if the pin no longer holds securely.
