The Casio F-91WM-9ADF is a contemporary reinterpretation of Casio's iconic vintage aesthetic, blending retro-inspired design cues with modern wearability. This compact digital watch features a distinctive gold-tone case that frames a multi-function digital display, complete with alarm and chronograph functionality. The black resin strap provides comfortable all-day wear whilst maintaining the lightweight character that has made Casio's vintage collection so enduringly popular across generations.

At Cassims & Co., we are proud to be an authorised retailer of CASIO watches, ensuring that every timepiece we offer is backed by the manufacturer's international warranty and our commitment to exceptional customer service. The F-91WM represents outstanding value in the quartz digital category, delivering reliable timekeeping and practical complications in a design that has transcended fashion trends for decades.

The digital module offers essential functions including a daily alarm, hourly time signal, and stopwatch capability, all easily accessible via the intuitive button layout. The LED backlight ensures legibility in low-light conditions, whilst the water resistance provides protection against splashes and brief immersion. This watch is equally at home as a daily beater, a nostalgic style statement, or a reliable travel companion.

Visit us at our Mall of the South boutique in Johannesburg to experience the F-91WM in person, or take advantage of our nationwide delivery service across South Africa. Our experienced team can assist with sizing, battery replacement, and all your horological needs. Should you require any maintenance down the line, our watch servicing and repairs team is always on hand to ensure your Casio continues to perform flawlessly for years to come.

Care Guide
  • Avoid exposing the watch to extreme temperatures, direct sunlight for prolonged periods, or magnetic fields which may affect the digital module's accuracy.
  • Do not operate the buttons whilst the watch is wet, as moisture may enter the case and compromise the electronics.
  • Remove the watch before showering, swimming, or engaging in water sports. The splash-resistant rating is not sufficient for submersion.
  • Clean the resin case and strap periodically with a soft, slightly damp cloth. Avoid harsh chemicals, solvents, or abrasive cleaners that may damage the gold-tone finish.
  • If the display becomes faint or the backlight dims noticeably, the battery may be nearing the end of its life. Visit our boutique for professional battery replacement to maintain water resistance integrity.
  • Store the watch in a cool, dry place when not in use. Avoid leaving it in direct sunlight or in vehicles where temperatures fluctuate significantly.
  • The resin strap may discolour slightly over time with exposure to UV light and skin oils. This is normal wear and can be minimised with regular cleaning.
