Dozens of models to choose from. All questions on Fixya need 'make model (what it is)' as the first 3 words.

Here are some guesses. The 'control cover' is where you put the back-up battery.

To change the 12/24 hour time format, open the CONTROL COMPARTMENT COVER on the bottom of the clock and adjust the 12/24 TIME FORMAT switch to the desired format .

Here are the instructions that came with my clock.

Hello, here is the instructions for setting your clock on this vehicle.


Press the H or the M button to enter the clock mode. Press and hold H until the correct hour appears on the display. Press and hold M until the correct minute appears on the display.
To change the time default setting from 12 hour to 24 hour, press either the H or the M button to enter the clock mode. Press the tune knob to select between the 12 or 24 hour display format. The clock mode automatically times out with the changed display format set as the current default setting.

There are several models of your watch not all of which appear to have a 12/24 hour display format.

Try this extract from a manual; press the MODE button six times to enter the 12/24 adjusting setting and then use the START/STOP or SPLIT/RESET button to change the time.

Press the mode button to return to normal operation.

Depending on the brand, if you push the clock button more than once it changes from am to pm to military time (24 hour) to am, to pm, etc.

When setting-up the time (by pushing the "mode" button), the alarm time set comes up first, followed by the time set.
When setting the proper hour in this mode, simply continue through the military "24 hour" cycle and the second cycle of 24 hours will be in the 12 hour format.
Continue through and finish the mode set-up function and your up and running. --

Push the "mode" button twice to enter the time change function. Once the display is blinking keep pushing the mode button until you see the "pm" icon on the LCD display. When that happens set the clock as you normally would using the 1-4 keys.

Remember to check if the 12 hour clock is set to AM or PM.

Good luck.

24 hour mode is all there is. Time to learn military time.
