Q: Is this watch suitable for swimming or showering?
A: The F-91W-3DG is water-resistant, which means it can withstand splashes, rain, and brief immersion in water. However, it is not recommended for swimming, diving, or showering, as prolonged water exposure may compromise the seal integrity.

A: Yes, the resin strap on the F-91W-3DG can be replaced. The watch uses standard 18mm spring bars, allowing you to fit aftermarket NATO straps or replacement resin straps if desired. Our servicing team can assist with strap replacements.
Q: How accurate is the quartz movement in this watch?
A: Casio quartz movements typically maintain accuracy within ±30 seconds per month under normal operating conditions. The digital module automatically accounts for month-end date changes and provides reliable timekeeping across all climate conditions.

Care Guide

- Avoid exposing the watch to extreme temperatures, direct sunlight for prolonged periods, or harsh chemicals including solvents, detergents, and perfumes that may degrade the resin materials
