Digital sports watch for everyday wear

The Casio LF-20W-3A is a unisex quartz watch with a square resin case and matching green resin strap. Its black digital display shows the month, day and date alongside the time. A buckle clasp secures the lightweight bio-based resin band on the wrist.

Water resistance limited to splashes

The 30 m rating protects against rain, hand-washing and brief immersion only. It is not suitable for swimming, showering or water sports. The fixed resin bezel and resin crystal complete the sealed construction without additional crown or pusher complexity.

Case thickness of 33.70 mm

This single dimension determines whether the watch sits flat under a shirt cuff or catches on fabric. Buyers who need a slimmer profile for formal wear should consider other models.
