Tips For Maintaining Accurate Time
Check your Casio Illuminator watch time often to keep it accurate. Compare it with a reliable clock or your phone. Adjust the time if you see any difference. This helps prevent your watch from running too fast or too slow.
Change the battery as soon as the light or display dims. A weak battery causes wrong time and stops the watch from working. Use the correct battery type for your model. Visit a watch shop if unsure how to replace it safely.
