Built for daily impact

The CASIO G-Shock DW-6900RL-1 uses a bio-based resin case and strap to deliver the classic 200-metre water-resistant digital watch in a more sustainable material. Quartz movement keeps time reliably while the fixed bezel and mineral crystal protect the black digital display from knocks and scratches.

Replaces older resin models

If your current G-Shock shows cracked straps or a hazy crystal, this model restores the same shock-resistant construction with updated bio-based resin components. The jump is worth it when you want the familiar 6900 case profile at 50.00 millimetres thick but prefer a plant-derived case and band over traditional petroleum-based resin.

Handles constant exposure

Under sustained outdoor use the mineral crystal resists abrasion from sand and salt while the buckle clasp keeps the bio-based strap secure during swimming or heavy activity. Digital readouts for month, day and date remain legible in bright sun, and the 200-metre rating holds through repeated pressure cycles without condensation.

Questions about this item

Will the 50.00 mm thick resin case clear my shirt cuff?

The case measures 50.00 mm thick so allow that clearance under a cuff; the bio-based resin is flexible enough to slide under most sleeves.

How do I set the digital time and date on the DW-6900RL-1?

Hold the top-left button until the seconds flash, then use the bottom-right button to change values and the bottom-left to move to the next field — the step people miss is pressing the top-left again to save.

When should I replace the mineral crystal or the bio-based resin strap?

Replace the mineral crystal if deep scratches affect readability; swap the bio-based resin strap when it shows cracks, hardening or lost elasticity.
