I will say, for exemple :

one-one- one- two-four-one-three.....

I use a casio (module 2178 or W-732 H).
This watch has a "countdown alarm mode". This can be set within the range of
1 second to 24 hours. When the countdown reaches zero, you will  hear an
alarm sounds for 10 seconds ( or you press any button, it will stop also).
You will hear the "beeps" very clear on the tape recorder.

If the activity is higher than 1999, 30 second intervals are useful !
