Two second hand

Two second hand
Waiting for my wife I look at my watch and notice that the second hand is not ticking along at one tick per second, it's more like it waits two seconds and then ticks twice in quick succession. Kind of curious.

I filmed this with my Samsung smartphone. At first it wouldn't focus. I then backed off until it came into focus and then when I came in closer it stayed in focus. Clever little camera.
