FAQ
Q: Is this the same as the original F-91W model?
A: The F-91WG-9QDF shares the same legendary digital module and case architecture as the classic F-91W, but features gold-tone printed accents on the bezel and dial surround, creating a warmer, more vintage-inspired aesthetic compared to the all-black or silver variants.
Q: How water resistant is this watch?
A: This model is designated as "water resistant," which means it can withstand splashes, rain, and brief submersion such as handwashing. It is not suitable for swimming, showering, or water sports. Avoid operating the buttons while wet.
Q: How long will the battery last, and can you replace it?
A: The CR2016 battery provides approximately seven years of continuous use under normal operating conditions. When replacement is eventually needed, our watch servicing team at Cassim & Co. can install a genuine Casio battery to maintain optimal performance and water resistance integrity.
Q: Will this watch fit my wrist?
A: The integrated resin bracelet is designed to fit wrist circumferences from approximately 145mm to 205mm. The compact 33.2mm case width is considered unisex and suits a wide range of wrist sizes. Visit our Mall of the South boutique for a personal fitting.
Q: Is this an authorised Casio product with a valid warranty?
A: Yes. Cassim & Co. is an authorised Casio retailer, and this watch comes with a full 1-year international Casio manufacturer's warranty covering defects in materials and workmanship. Proof of purchase from our store validates your warranty coverage.

A: Absolutely. The F-91W series is legendary for its durability and longevity. The resin case and bracelet are impact-resistant, lightweight, and hypoallergenic. Millions of these watches have been worn daily for decades with minimal maintenance beyond the occasional battery change.
Q: Does this watch have a backlight for night-time visibility?
A: Yes, the watch features a micro LED light (often called an "electro-luminescent backlight") activated by the top-left button. It illuminates the entire digital display for easy reading in darkness or low-light conditions.
Warranty
- This Casio watch is covered by a 1-year international manufacturer's warranty from the date of purchase.
- The warranty is valid only when the watch is purchased from an authorised Casio retailer such as Cassim & Co.
- Coverage includes manufacturing defects in materials and workmanship under normal use conditions.
- The warranty does not cover normal wear and tear, scratches, bracelet stretching, or cosmetic deterioration of resin materials due to aging or UV exposure.
- Battery replacement is considered a consumable service and is not covered under warranty, though the initial battery is guaranteed to last approximately seven years.
- Water damage resulting from misuse (such as operating pushers underwater, exceeding water resistance limits, or failure to maintain seals) is excluded from warranty coverage.
- Damage caused by accidents, improper handling, unauthorised repairs, or modifications voids the warranty entirely.
- To claim warranty service, present your original proof of purchase from Cassim & Co. Warranty service is provided through authorised Casio service centres.
- Cassim & Co. offers ongoing after-sales support including battery replacements, bracelet adjustments, and general maintenance beyond the manufacturer warranty period.
Care Guide
- Wipe the case and bracelet regularly with a soft, lint-free cloth to remove skin oils, dust, and environmental residue that can dull the finish over time.
- Avoid exposing the watch to extreme temperatures (below 0°C or above 60°C), as this may affect battery performance and LCD display clarity.
- Do not operate the pushers when the watch is wet, as moisture may enter the case and damage the digital module. Dry the watch thoroughly before using any functions.
- Although water resistant, this model is not suitable for swimming, bathing, or water sports. Remove before showering or exposure to soap, which can degrade seals and resin materials.
- Store the watch in a cool, dry environment away from direct sunlight when not in use. Prolonged UV exposure may cause gradual fading of the resin material.
- If the display becomes faint or functions become erratic, the battery likely requires replacement. Contact our servicing team promptly to prevent potential leakage damage from an exhausted battery.
- The resin bracelet may be cleaned with mild soap and water if necessary, but ensure the watch is thoroughly dried immediately afterward and avoid submerging.
- Have the watch inspected during battery replacement to ensure water resistance seals remain intact, particularly if you use the watch in humid or outdoor environments regularly.
