Good day Sir, This model (WR50M) has four buttons, from left to right, top to bottom: 1) Set; 2) Start/Stop; 3) Mode; and 4) Indiglo.

To set or change the time:

1.Press and hold Set and Start/Stop simultaneously; the seconds will start to blink

2.Release both buttons
Use Mode button to toggle through to Hours, Minutes, etc.

3.When desired number (such as Hours/Minutes) starts to blink, use Start/Stop button to change number

4.When done, hit Set

have a nice day.

Press the MODE button until you get to the AL (ALARM) screen. Press Start/Split (Stop/Reset) (upper right button) repeatedly to turn the alarm and chime are off. If that did not help the manual can be found at www.timex.com at the bottom of the page click on manuals/downloads, click on manual downloads go to Digital Chrono/Alarms/Timers and click on the manual. Hope this helps.

just press the lap/reset button then press the mode button a letter A should appear

Solution #2 by Guest, posted on May 13, 2008 solved my problem. OUTSTANDING solution #2!

1. Hold in the MODE button until the alarm time appears.

2. VERY IMPORTANT - release and TAP the MODE button AGAIN, and the time should appear with the seconds flashing.

3. Use StART/Stop to choose among seconds, hours, and minutes, and

4. Use ADJUST to increase the selected number

5. Press MODE to put the thing back in regular operational mode.

After several attempts with other directions over the last four months, these 5 steps WORKED.

Hold down the adjust button bottom right then press the mode button top left you will notice the a or p that stands for am/pm will disappear & reappear. If you have an a or p on your display then you are out of military time.

This site should help.

hold down the "adjust" button (bottom right) as you press the "start/stop" button (top right). this will cycle through the alarm functions. I believe one is an hourly chime and the other is the alarm. just keep pressing until there are no icons below the time. that should do it.
