FAQ

Q: Is the F-91WB-2A1DF suitable for swimming?

A: This watch is water resistant, meaning it can handle splashes and brief exposure to water such as handwashing or rain. However, it is not recommended for swimming, showering, or any water sports activities. Avoid pressing buttons when the watch is wet.

Q: What does bio-based resin mean?

A: Bio-based resin is a sustainable material derived from renewable plant-based sources such as castor oil, rather than traditional petroleum-based plastics. Casio's bio-based resin maintains the same durability and performance as conventional resin whilst reducing environmental impact.

Q: How do I activate the LED backlight?

A: Press the top-left button (LIGHT) to activate the LED backlight. The illumination will remain active for approximately 1.5 seconds, providing visibility of the digital display in low-light conditions.

Q: Can the battery be replaced, and how long does it last?

A: Yes, the CR2016 battery can be replaced. Under normal usage conditions, the battery provides approximately seven years of operation. Visit Cassims & Co. for professional battery replacement services to maintain your watch's water resistance integrity.

Q: Is this watch suitable for both men and women?

A: Absolutely. The F-91WB's compact 38.2mm case size and lightweight 21-gram construction make it a versatile unisex timepiece that suits a wide range of wrist sizes and personal styles.

Q: What is the difference between the F-91WB and the original F-91W?

A: The F-91WB series features a translucent coloured bio-based resin case and bracelet, representing an evolution of the classic F-91W design with enhanced sustainability credentials. The core digital functions and case dimensions remain identical to the legendary original.

Q: Does this watch come with the international Casio warranty?

A: Yes, when purchased from Cassims & Co. as an authorised Casio retailer, this watch includes a full 1-year international manufacturer warranty covering manufacturing defects in materials and workmanship.

Warranty
  • This watch is covered by a 1-year international Casio warranty from the date of purchase when purchased from an authorised retailer such as Cassims & Co.
  • The manufacturer warranty covers defects in materials and workmanship under normal use conditions.
  • The warranty does not cover normal wear and tear, including scratches, deterioration of the resin band or case, battery depletion, or crystal damage.
  • Water damage resulting from improper use (such as operating buttons underwater or exceeding the stated water resistance) is not covered under warranty.
  • Accidental damage, misuse, unauthorised modifications, or repairs performed by non-authorised service centres will void the warranty.
  • Battery replacement is considered a maintenance service and is not covered under the manufacturer warranty.
  • To validate your warranty, retain your original purchase receipt from Cassims & Co. and present it along with the watch for any warranty claims.
  • For warranty service or technical support, contact Cassims & Co. as your authorised Casio retailer for guidance and assistance.
Care Guide
  • Wipe the case and resin bracelet regularly with a soft, dry cloth to remove perspiration, moisture, and dirt that can cause deterioration over time.
  • For stubborn dirt on the resin components, use a soft cloth slightly dampened with mild soapy water, then wipe immediately with a dry cloth. Never use solvents, thinners, or chemical cleaners.
  • Avoid exposing the watch to extreme temperatures, direct sunlight for prolonged periods, or placing it near heating appliances, as this may cause discolouration or deformation of the resin.
  • Although water resistant, avoid operating the buttons when the watch is wet or submerged, as this may compromise the seal and allow moisture ingress.
  • Store your Casio watch in a cool, dry location away from strong magnetic fields, chemicals, and solvents when not in use.
  • If the digital display becomes difficult to read or the LED backlight dims significantly, the battery may require replacement. Visit an authorised service centre to ensure proper battery installation and seal integrity.
  • The bio-based resin material maintains the same durability as conventional resin, but avoid excessive contact with oils, cosmetics, and harsh chemicals that may affect the finish.
  • Regularly check the bracelet and buckle for signs of wear or looseness to prevent accidental loss of the watch.
