This clock tells time not in hours, minutes or seconds, but in years. It’s designed to very, very slowly make its way around the dial as you age.
Each number on the dial corresponds to a 7-year period of your life. By taking a standard clock mechanism and slowing it to 1/61320th of the speed of a standard timepiece, artist Betrand Planes’ Life Clock is able to tell time over an 84 year period before it makes one full rotation around the dial.
If you manage to live through a full 360-degree sweep of the year hand, you’re doing pretty darned well.
