Description
The Casio Vintage B640WGG-9DF is a contemporary reinterpretation of the iconic digital timepiece aesthetic that defined an era. With its gold-tone stainless steel case and integrated bracelet, this quartz-powered watch delivers unmistakable retro charm paired with modern reliability. The distinctive glitter-effect dial surround frames a multi-function digital display, creating a statement piece that bridges nostalgic design with everyday practicality.
Measuring 38.9mm in length and 35mm in width with a modest 9.9mm case height, this unisex timepiece sits comfortably on any wrist. The stainless steel construction ensures durability, while the 50-metre water resistance provides adequate protection for daily wear. The quartz movement runs on a CR2016 battery with an approximate three-year lifespan, and functional features include an LED backlight for low-light visibility, a 1/100-second stopwatch, countdown timer, and multi-function alarm — all the essentials for a modern digital watch enthusiast.

FAQ
Q: Is this watch suitable for swimming?
A: The B640WGG-9DF has 50-metre water resistance, making it suitable for splashes and brief immersion such as handwashing or light rain. However, it is not recommended for swimming, showering, or any water sports, as the pushers should not be operated underwater and prolonged exposure may compromise the seal.
Q: How do I adjust the bracelet to fit my wrist?
A: The stainless steel bracelet features removable links that can be adjusted for a custom fit. We recommend visiting our Johannesburg showrooms where our team can professionally size the bracelet to your wrist at no additional charge. Alternatively, any qualified watchmaker can perform this service.
Q: What is the battery life and how much does replacement cost?
A: The CR2016 battery provides approximately three years of use under normal conditions. When replacement is needed, Cassims & Co. offers battery replacement services. Battery replacement costs are separate from warranty coverage, as batteries are considered consumable items subject to normal depletion.
Q: Does the LED backlight illuminate the entire display?
A: Yes, the LED backlight provides uniform illumination across the digital display, making the watch easily readable in low-light conditions. The backlight is activated via the designated pusher and remains lit for a few seconds before automatically switching off to conserve battery life.
Q: Is this watch suitable for both men and women?
A: Absolutely. The B640WGG-9DF is designed as a unisex timepiece with its 35mm width falling within the versatile size range that suits a variety of wrist sizes. The retro-inspired aesthetic and gold-tone finish make it a popular choice across all genders.
Q: What functions does the stopwatch offer?
A: The stopwatch measures elapsed time to 1/100th of a second accuracy and can run continuously for up to 24 hours. It includes split time and lap time functions, making it useful for timing intervals, workouts, or any activity requiring precise time measurement.
Q: Does this model come with the original Casio packaging?
A: Yes, every B640WGG-9DF purchased from Cassims & Co. arrives in original Casio packaging with all accompanying documentation, warranty cards, and instruction manual. As an authorised retailer, we guarantee 100% authentic Casio products with full manufacturer support.

Care guide
- Daily Care: Wipe the case and bracelet with a soft, lint-free cloth after wear to remove perspiration, oils, and dust that can accumulate throughout the day.
- Water Exposure: While rated to 50 metres, avoid operating the pushers when the watch is wet or submerged. Rinse with fresh water after exposure to chlorinated or salt water, then dry thoroughly.
- Storage: When not wearing your watch, store it in a cool, dry place away from direct sunlight, extreme temperatures, and magnetic fields which may affect timekeeping accuracy.
- Bracelet Maintenance: The stainless steel bracelet can be cleaned periodically with a soft brush and mild soapy water. Rinse thoroughly and dry completely. Pay attention to the areas between links where dirt may accumulate.
- Crystal Protection: The mineral crystal is scratch-resistant but not scratchproof. Avoid contact with abrasive surfaces, hard impacts, and sharp objects to maintain clarity.
- Chemical Exposure: Keep your watch away from solvents, detergents, perfumes, cosmetics, and other chemicals that may damage the case finish, seals, or bracelet.
- Battery Service: When the display dims or functions become sluggish, have the battery replaced promptly by a qualified watchmaker. Delayed replacement may result in battery leakage that can damage the movement.
- Professional Servicing: Every few years, consider having the watch inspected to verify water resistance seals and overall condition, particularly if you expose it to water regularly.
