Is it really gonna be enough ?
I I think it is because if you think about it , the watch , although it's only a tiny amount it's it's um  it's always moving for the whole day and they don't run out over night when you leave them on the side.
Okay.
And th for the same the same reason , you're only using it for a v incredibly short amount of time just to send the signal and then you're finished with it
