Choose the Right Casio Support Route
- Watch repair or battery service: read Casio’s watch-repair instructions and confirm the appropriate service location.
- Keyboard or piano: use Casio’s musical-instrument service directory; Privia and Celviano have dedicated locator options.

- Purchase from another retailer: ask that seller about its return process, and use Casio for applicable manufacturer-support questions.
Casio Watch Repairs and Warranty Questions
Casio recommends authorized watch service because work can require resealing, pressure testing or calibration. Before shipping, record the model number, explain the requested work and follow the current service instructions. Use tracked shipping and retain the receipt.
The official Casio repair portal provides repair requests and status checks. For paid work, Casio evaluates the watch and supplies an estimate before proceeding with approved repairs or battery replacement. Confirm the current shipping destination through the service process instead of relying on an old directory address.
Warranty coverage depends on the product and its written terms. Keep dated proof of purchase and the warranty documentation. Ask which provision applies if service is declined, and request an estimate before authorizing work that is not covered.
Casio.com Returns and Refunds
Casio’s U.S. return policy describes a 30-day return period for eligible direct purchases. Obtain a return merchandise authorization (RMA) before shipping anything back. Return the required accessories and any included promotional gift, and keep tracking until the refund is complete.
Shipping charges, exclusions and condition requirements apply. Casio lists a 5% restocking charge for non-defective returns and refused shipments; watches must be in new condition for a full refund. Review the current policy for your purchase before arranging a return. An item bought from a different seller follows that seller’s return process.
Following Up on an Unresolved Casio Case
Keep the order or repair reference, contact dates, delivery proof, estimate and any promised next step together. Reply in the existing support thread with a short explanation of what remains unresolved and the outcome you are requesting. If a repair is delayed, ask whether the issue is inspection, parts availability, approval or payment.
