Resetting the seconds between 30 and 59 adds one minute.

When the watch is paired with a phone running CASIO WATCHES, the time is set for you: it connects at around 12:30 a.m., 6:30 a.m., 12:30 p.m. and 6:30 p.m. Setting the time by hand is for when it cannot connect.

To take the time from the phone now, move the phone close to the watch and press D in the Timekeeping Mode: TIME flashes, then OK shows.

12/24-hour format: press C five times from the step reminder setting, then D to switch between 12H and 24H. In 12-hour format, P marks p.m.

In any mode, hold C for at least one second to go back to the Timekeeping Mode.
