SOURCE: Timex 1440 sports wach chime disable

Press the mode button until the Alarm apears. Press the Start/Stop button to turn the alarm on/off and remove/add the chime. Whew! I had to figure this out after my 3 year old turned the chime on!

think of the top buttons from left to right as A & B and the bottom buttons from left to right as C & D. The way to turn the chime off and on is by holding the C & D Buttons simatainiously and the pressing the B button. This will allow you to turn the Hourly Chime Off and On. When you see the digital chime pattern in the display the chime is on. When no pattern is shown the chime is off. Hope this helps the ton of people who have purchased these watches & either did not have instructions with or lost them. This perticular watch has been annoying the whole household for quite sometime and has now been put to rest..lol

Based on insructions for another watch, I just figured this one out. The steps would be:
Get in Alarm mode (press mode button)
Then you can cycle through the following by pressing the ST/STP button
1. Alarm on
2. Chiime on
3. Alarm and Chime on
4. Alarm and Chime off
You can see this with a magnifying glass and watch the center and right hand circular icons at the top of the display.get highlighted.

You have a feature on your watch labled OPTION. You can find this by pushing the topright button on your watch until it appears on the screen. then scroll down using the knob until you find hourly beep. From here you can turn it on or off.

to turn off hourly chime on the times wr 30m, simply press (in any mode, i just use the regular clock mode) the start/stop button (top right hand button) once (for about half a second).
  if you don't hear anything, you've turned off the hourly chime!  if you hear two short beeps, you've turned on the hourly chime.    turning the chime off/on is cyclic.  if you press once and hear nothing, it's off.  if you press again, you'll hear two beeps and the hourly chime is now on.    a lot of times that button hits my wrist (i wear it on my left hand) by accident, and that's how the chime turns on and off.  i hope this helps someone.
