Troubleshooting

Setup, Compatibility & Care
To set up your GA-900-4A, ensure the battery is seated correctly and follow the digital module instructions to synchronize the analog hands with the digital time display. The watch is compatible with standard wrist sizes; the resin strap is adjustable via the buckle holes to ensure a snug fit. To maintain the watch, rinse the resin band with fresh water after exposure to salt water or heavy sweat. Avoid using harsh chemicals or solvents on the casing, as they can degrade the resin material over time. Keep the crystal surface clean by wiping it with a soft, microfiber cloth to prevent minor abrasions.
