How could an alarm clock have more concept of time-keeping?
We got the inspiration from the sandglass.
As shown in the picture, when the alarm clock rings but you still want to lie in, you can turn the sandglass over to prolong 5 minutes (The default is 5) by built-in gravity sensor. You can see the time you remain through the transparent case as well. After 5 minutes, you can turn it over again until getting up to put it on the base outside the bedroom for charging.
This alarm clock emphasized the concept that to keep your time, you need buy your time first.
