How do you tell on a watch if the dial is on pm or am?

To determine if the dial on a watch is set to AM or PM, check for any indicators or markings, such as a small sun or moon icon. Many analog watches with a date function will also change the date at midnight (AM) rather than noon (PM). If the watch has a 24-hour format, numbers above 12 indicate PM hours. Additionally, if you know the last time you adjusted the watch, you can compare it to the current time to deduce whether it is AM or PM.
