1. Identify Watch Buttons

There are four buttons on your watch.


  1. The top left button (A) is "Reset"
  2. The top right button (D) is "ST/STP," which stands for "Start" and "Stop."
  3. The bottom left button (B) is "Mode."
  4. The bottom right button (C) activates the light.

2. Hold the Reset Button

To begin setting the time, hold the "Reset" button (A) until you hear a beep.


Three out of the four screens on the watch will start to blink. That means you're ready to set the time.

3. Press the Mode Button

Press the bottom left button (B), "Mode" to access the hour setup.

Note that pressing this button will not actually change the hour, but the hour side of the time display will start to blink. This indicates that you're ready to continue to the next step to set the hour.


4. Use ST/STP to Adjust the Hour

Press the "ST/STP" button (D) to change the hour.

Each time you press the button, the hour will increase until it hits 12, after which it will restart at 1.

Press the "Mode" button (B) again to set the hour. When you do, the hour side will stop blinking and the minutes will be ready for setting.


5. Use ST/STP to Adjust the Minutes

Press the "ST/STP" button (D) on the top right to increment minutes.

Each time you press the button, the number of minutes increases by 1.

Once your watch is set to the correct time, press the "Reset" button on the top left (A) to set the minutes.


Want a 24-Hour Time Display?

You can set the time on an Armitron Pro Sport to a 12-hour clock or 24-hour clock, called military time in the United States. The watch sets to 12-hour-time be default.

To switch to a 24-hour time display:

  1. Hold the "Reset" button (A) until you hear a beep.
  2. Press the "ST/STP" button (D). The "AM" or "PM" icon to the left of the time will go away.
  3. Press the "Reset" button (A).

How to Add Multiple Time Zones

If you're traveling and need to know the times in multiple time zones, you can set the time for another different time zone on your watch.

Follow the steps below to set an additional time:

  1. To enter the Second Time Zone mode, press the "Mode" button 3 times.
  2. Press the "Reset" button. The hours icon will start flashing.
  3. Press the "ST/STP" button to change the hours.
  4. When you've set the correct hour, press the "Mode" button again. This will set the hours and allow you to change the minutes. The minutes icon will begin flashing.
  5. Press the "ST/STP" button again to increment the minutes.
  6. Once you've selected the correct minutes, press the "Reset" button to set the time.
  7. Press the "Mode" button to return to your main time zone.

How to Change the Time on an Armitron Analog Watch

Follow the steps below, from the Armitron Analog Watch manual, to set the time:

The crown on an Armitron analog watch determines how you set it.

1. Identify Crown Position

The watch crown can be pulled into three positions:

  • A. Neutral: This is the normal operating position.
  • B. Position to set the date: For watches with date windows.
  • C. Position to set the time.

2. Pull the Crown Out

3. Push Crown Back In

Push the crown back into position A to resume time keeping. You should see the second hand start to move again.

Caring for Your Armitron Watch

Most Armitron watches, both Sport and Analog, are water resistant. Analog watches likely have a depth limit on the back of the watch; ensure you're not wearing your watch if you go below this depth. For Sport watches or any Armitron with a push button, do not use any buttons under water.

Armitron recommends taking your watch to a local jeweler to replace the battery. For Analog watches, the brand suggests having your local jeweler replace the gasket and O-ring every time you have the battery changed to ensure the watch remains waterproof.

For larger repairs or maintenance, including cleaning, lubrication or having a crystal replaced, Armitron has a list of approved service centers where you can send your watch.
