Press and hold the lap/reset button will show the alarm time again, but it will hold there. While holding this lap/reset button, press the start/stop button (labeled). This will turn on (or off) the alarm (tiny indicator). Press this start/stop button repeatedly (while still holding the lap/reset button and you will see the indicator turning on and off with each press.

Te alarm will repeat daily until it is turned off.

the mode button controls the different functions of the watch.  time, alarm time, stopwatch, timeset, alarmset, in a repeating cycle.  Make sure you are on the time function (seconds ticking and changing every second, but not flashing twice per second.  This is the normal mode that shows the time.
 A press of the lap/reset button (labeled) will show the alarm time, Unpress will show the time of day. Press again toshow the alarm time. Press and hold the lap/reset button will show the alarm time again, but it will hold there.  While holding this lap/reset button, press the start/stop button (labeled).

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.
