The Armitron All-Sport is a unisex style of watch made by Armitron that features a digital readout and four buttons around the outer dial for adjusting various aspects of the watch. It can set alarms, keeps the time as well as the date, and has a built-in backlight. Accessing and adjusting these various settings is a fairly simple process.

Setting Date, Time and Alarm
- To enter the date and time setting mode, press and hold the "mode" button, located on the top-left of the watch. Continue holding this button until the display begins to flash. This first display is the alarm setting, should you choose to set an alarm to go off. If you'd like to set the alarm, use the "alarm" button on the bottom-right of the watch to advance the hours to the desired one. Then press the mode button again; this will cycle through the minutes and seconds of the alarm to allow you to set those as well. Once you have set the alarm, you can press the "date" button at the top-right of the watch to proceed to the regular time setting. These numbers, which will now be flashing, also are adjusted by pressing the alarm button to change them. Pressing the date button again will now cycle through the hours, minutes, seconds and the date. As you continue to press the date button, the All-Sport will continuously cycle through these options; don't worry if you forget to set one, you can simply press the date button a few times until you get back to the setting you need to change. Once the alarm, time and date have all been set, you can press the mode button one more time to exit to the normal watch mode that will display the date and time.
Using Chime and Alarm
- The Armitron All-Sport features both an alarm and an hourly chime. The alarm function will cause the watch to continuously beep at the selected time until you turn it off by pressing a button. The chime will cause the watch to beep once every hour. You can turn both these features on and off by pressing and holding the alarm button and while holding it pressing the date button. The first time you do this, the chime will turn on and a small house symbol will be displayed on the watch face. Performing this button-pressing sequence again will turn on the alarm, which in turn displays a small clock icon on the watch face. Each successive pressing of this button sequence will alternate between the chime and the alarm, turning them either on or off.
- The All-Sport also features a built-in backlight to help you view the watch in dark conditions. This light can be activated by pressing the "light" button on the bottom-left of the watch. Pressing this button is the only way to activate the light, and doing so will only cause the watch to illuminate for a few seconds at a time.
