Frequently asked questions
How much does “Restarting or stuck on logo” cost?
Smartwatch diagnostics are free. The exact price depends on the model, root cause and part cost, and is approved before work begins.
Can the fault be diagnosed from a photo?
A photo can show external damage and help identify the model. Power, charging and board faults require measurements after the device is received.
Can I send the watch by courier?
Yes. We accept devices from across Serbia. Send the model, symptom and city first so we can advise on packing and whether to include the charger.
Do you begin repair immediately?
No. We diagnose first, report the cause, available options and exact price, and begin only after your approval.
