Description
The Casio G-Shock GA-100-1A4DR is an icon of shock-resistant engineering and bold design. This quartz analogue-digital chronograph combines rugged construction with striking black and red aesthetics, making it the ultimate tool watch for those who demand durability without sacrificing style. The distinctive layered case design, robust resin construction, and highly legible combination dial define the GA-100 series as one of G-Shock's most recognisable silhouettes.
At Cassim & Co., we are proud to offer the full range of CASIO watches, including this legendary G-Shock model. The GA-100-1A4DR features a shock-resistant case measuring 55 × 51.2 × 16.9mm, crafted entirely from resin with magnetic resistance to ensure reliable performance in demanding environments. The watch offers 200-metre water resistance, making it suitable for recreational diving and water sports, while the mineral crystal provides excellent scratch resistance.
The dual-display configuration combines three analogue sub-dials with a digital LCD, offering comprehensive timekeeping functions including world time, stopwatch, countdown timer, and five daily alarms. Red accents on the hands and dial elements contrast beautifully against the matte black case and bezel, while the luminous markers ensure readability in low-light conditions. This quartz movement is powered by a CR1220 battery with an approximate two-year lifespan, ensuring long-term reliability.
Whether you're seeking a dependable sports watch, a rugged everyday timepiece, or simply appreciate the bold design language that has made G-Shock a global phenomenon, the GA-100-1A4DR delivers exceptional value. Visit us at our Mall of the South boutique in Johannesburg to experience this watch in person, or take advantage of our nationwide delivery service across South Africa. Our watch servicing and repairs team is always available to assist with battery replacements and any technical support you may require.
Care guide
- Water Resistance: While rated to 200 metres, avoid operating buttons or crown underwater. Rinse with fresh water after exposure to salt water or chlorine.
- Cleaning: Clean the resin case and strap regularly with a soft cloth dampened with mild soap and water. Dry thoroughly after cleaning.
- Impact Protection: Although shock-resistant, avoid extreme impacts such as dropping the watch onto hard surfaces from significant heights.
- Temperature: Avoid exposing the watch to extreme temperatures (below -10°C or above 60°C) for extended periods, as this may affect battery life and resin materials.
- Chemicals: Keep away from solvents, detergents, perfumes, cosmetics, and other chemicals that may damage the resin case or strap.
- Storage: When not in use, store in a cool, dry place away from direct sunlight to prevent resin discolouration.
- Battery Replacement: Have the battery replaced by an authorised service centre to maintain water resistance. Do not attempt to replace the battery yourself.
- Magnetic Fields: While magnetic-resistant, avoid placing the watch directly on speakers, magnetic clasps, or other strong magnetic sources for extended periods.
- Strap Maintenance: The resin strap may accumulate dirt and oils. Clean regularly and allow to dry completely before wearing.
- Regular Servicing: We recommend a general check-up every 2-3 years to ensure water resistance gaskets remain effective and all functions operate correctly.
