FAQ
Q: What is the difference between analogue-digital display and fully digital G-Shock models?
A: The GA-900-2A features an ana-digi display, combining traditional analogue hands for timekeeping with a digital LCD module for advanced functions like world time, stopwatch, and countdown timer. This hybrid approach offers the intuitive readability of analogue time display alongside the functionality of digital complications, making it ideal for users who appreciate both classic watch aesthetics and modern tactical features.
Q: Can I wear this watch while swimming or diving?
A: Absolutely. With 200-metre water resistance, the GA-900-2A is suitable for swimming, snorkelling, and recreational diving. It is designed to withstand significant water pressure and is fully protected against immersion. However, it is not designed for saturation diving or professional underwater operations requiring specialised dive instruments.
Q: How long will the battery last, and can it be replaced locally?
A: The GA-900-2A is powered by a CR2016 battery with an approximate lifespan of seven years under normal use. When replacement is eventually required, our authorised service team at Cassims & Co. can perform the battery change using genuine Casio components, ensuring your watch maintains its water resistance and warranty coverage.
Q: What does the shock-resistant construction actually protect against?
A: G-Shock's shock-resistant construction uses a floating module suspension system that protects the movement from impact, vibration, and mechanical shock. This design allows the watch to withstand drops, knocks, and jarring movements that would damage conventional timepieces, making it ideal for active sports, outdoor work, and tactical applications.
Q: Is the resin strap durable enough for long-term daily wear?
A: Yes. Casio's resin straps are engineered for exceptional durability, flexibility, and resistance to UV degradation, perspiration, and temperature extremes. The GA-900-2A features a dual-layer construction with textile reinforcement, further enhancing strength and comfort. With proper care, the strap will provide years of reliable service.
Q: Does this model feature automatic LED illumination?
A: The GA-900-2A is equipped with LED illumination for the digital display, activated manually via the designated button. This ensures clear visibility of digital functions in low-light conditions. The analogue hands and markers are also designed for enhanced legibility in challenging lighting environments.
Q: Will this watch work in extreme temperature conditions?
A: G-Shock watches are designed to operate reliably across a wide temperature range, typically from -10°C to 60°C. The resin construction remains flexible in cold conditions while resisting deformation in heat, and the quartz movement maintains accurate timekeeping across this spectrum. This makes the GA-900-2A suitable for use in diverse climates and demanding environments.
Warranty
- This watch is covered by a 1-year international Casio warranty from the date of purchase.
- The warranty is valid only when the watch is purchased from an authorised Casio retailer such as Cassims & Co.
- The warranty covers manufacturing defects in materials and workmanship under normal use conditions.
- The warranty does not cover normal wear and tear, including scratches, abrasions, or fading of the resin case and strap.
- Battery replacement is not covered under warranty, as batteries are considered consumable items with a defined service life.
- Water damage resulting from improper use, such as operating buttons underwater or exceeding the stated water resistance rating, is excluded from warranty coverage.
- Accidental damage, including impact damage from drops or crushing, is not covered by the manufacturer's warranty.
- Modifications, unauthorised repairs, or servicing by non-authorised technicians will immediately void all warranty coverage.
- To make a warranty claim, the original proof of purchase and warranty card must be presented to an authorised Casio service centre.
- Cassims & Co. is an authorised Casio retailer and can assist with warranty claims and direct you to approved service centres in South Africa.
Care guide
- Rinse the watch with fresh water after exposure to saltwater, chlorine, or perspiration to prevent residue buildup on the case and strap.
- Clean the resin case and strap periodically using a soft brush and mild soap solution, paying particular attention to the textile inserts and areas around the buttons.
- Avoid exposing the watch to harsh chemicals, solvents, detergents, or insect repellents, which may damage the resin finish or compromise water resistance seals.
- Do not operate the buttons while the watch is submerged or wet, as this may allow water ingress and void the water resistance guarantee.
- Store the watch in a cool, dry location away from direct sunlight when not in use to prevent premature UV degradation of the resin components.
- If the watch is not worn for extended periods, remove it from storage periodically to ensure the battery remains active and the digital display functions correctly.
- Have the battery replaced by an authorised service centre when low battery indicators appear to maintain water resistance integrity and ensure proper sealing.
- Avoid exposing the watch to strong magnetic fields, which may temporarily affect timekeeping accuracy until the watch is removed from the magnetic source.
- Do not attempt to open the case back or service the movement yourself, as this will void the manufacturer's warranty and may compromise shock and water resistance.
