SHAKE N WAKE: TO CHANGE TO MILITARY TIME
Hit Mode 3 times to set the time
Hit Reset/TimeSet twice to make hours flash
Now keep hitting StartStop/Adjust repeatedly. After you go through 12 hours of AM then 12 hours of PM it will start going through the hours in military time.

To change your Armitron WR165 watch from military time (also known as 24-hour time) to 12-hour time, you will need to follow these steps:

1. Press and hold the "mode" button until the display shows the current time format (either 12H or 24H).
2. Press the "set" button to toggle between the two time formats.
3. When the desired time format is displayed, press the "mode" button to exit the setting mode and save the new time format.

If you are having trouble changing the time format on your watch, you may want to consult the user manual for your specific model, as the steps may vary slightly depending on the version of the watch you have. You can also try contacting Armitron customer support for further assistance.

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.

Hi Harry,

Your Module number is 2271.
1. To set the time, press and hold button A (left top) until Seconds digits start to flash.
2. Press button D (lower left) to move flashing in the following sequence to change other setting:
Seconds >> Hour >> Minutes >> 12/24 Hour Format >> Year >> Month >> Day >> (Then back to Seconds)
3. While a setting is flashing, use E (+) (bottom right) and B (-) (top right) to change it.
Note: When in the 12/24 Hour Mode, use E and B to toggle between 12-Hour and 24-Hour Mode.
4. Press buton A to exit setting screen.
Your time should now be set.

To change from 24 hour to 12 hour, you hold down the "Mode" button until it switches from 24 hour to 12 hour or vice versa. To change the time zone, you hold down the "Set" button until the time zone that you set it in flashes (like "LAX" on my watch). Then you press the "Receive/Start/Stop" button to choose the specified time zone you want. To set for daylight savings time ("DST" on the watch), after holding the "Set" button and having the time zone flash, you could press the "Mode" button. It will give you a few options for the daylight savings time (Auto, On, or Off). I chose the "On" option, which immediately changed for daylight savings time. If you manually want to change the time, you could hold down the "Set" button and keep pressing the "Mode" button until the time starts flashing on your watch, then pressing the "Receive/Start/Stop" button until you change it to the time that you want. You could also set the watch to beep or chime after pressing the set button if you wanted to know that piece. You hold down the "Set" button when you are done to get it to stop flashing. These instructions worked for my Timex T5G341 Universal Radio Control Watch. I hope this helps.
