Thread: How do I turn off the hourly chime on my Athletic Works stopwatch?

The stopwatch keeps beeping every hour and it's driving everybody at home insane. Nothing useful showed up after searching the web for the part no. (AW60448W) or even the brand name. I figured out how to turn off the alarm, but not the hourly chime. Can anybody help?

Without the make and model name its like shooting in the dark.
