It seems that shifting sands will eternally provide a gauge of the passage of time - even if it happens via an LED screen. Sand+Time watch offers its wearer the time in modern electronic hours, but the form of the interface has also been borrowed from an old sand hourglass.
Winner of the Red Dot Design Award in 2006, Sand+Time Watch by Russian graphic designer Balykin Pavel, has a LED screensaver made to look like a sandglass. A push of a button switches the screen to display the time in numbers.
Instead of digital digits, or sweeping hands, this concept watch gives its face an hourglass form and tells time using LCD pixels like so many trickling grains of sand.
The watch functions in two modes: the first, the screensaver, takes the form of a sand hourglass counting a certain time unit set by the user to their preference with the default setting for the hourglass is one minute. The second mode displays the time in numbers. The press of a button displays the time, when the watch is in screensaver mode.
The light-emitting diode technology often used in watches is the basis of the screen image while modern materials compose the watch - rubber for the bracelet, and plastic for the case, which can be produced in several colors.
