Time Machine
Many sizes it is both round and square
It tracks our life with no moment to spare.
It ticks, it tocks, with no end in sight
It sits on our wrist with all it might.
Hold on for the ride with either metal or leather
Heavy as a brick or light as a feather
Under water it works or maybe not
Oh no it stopped I will loose my spot
Always a good friend so near and dear
Without it, I know, there is much to fear
