Feeling of time / Watch

All along, we always look at the time, listening time "ticking" walk. Does that mean the other way to feel time?
In some cases, we hold own pulse to calculate the time.
"Feel the time" watch is through their own changes to make the wearer feel the passage of time.
Every 5 seconds, the watch will gradually expand or shrink, so the wearer can feel the beating of time.
