Why do alarms set on my S2 watch do nothing?

A

AC Question

If I set an alarm using S voice then nothing happens. It doesn't appear on my phone. I've managed to find that the alarm has been set by asking S voice what alarms are there.

I don't know if the watch vibrates or not when the alarm is supposed to go off - if it does it's useless because the watch is on the charging stand when I sleep not on my wrist.
