Design submitted by Wilhelm from South Africa.
Wilhelm says: The idea for this watch module came from the square metal grids used in the building industry, combined with 2 methods for reading time, the normal digital “grid” mode for easy time telling and the “quattro” binary method for reading digital time, hence the name “Quattrogrid”.
The EL luminous LCD module has 8×9 separate horizontal and 8×9 separate vertical lines, forming the square grid shaped graphic display. The LCD glass has a black checkered print of 81 squares between the gridlines. The luminous through the “open” gridlines displays the desired graphic for reading the time.
This watch will be for those people who prefer a digital watch that can be switched between easy reading and advanced binary reading to make it more interesting and a LCD display that is always “on” in idle mode ready to read without the backlight.
The uniqueness of the Quattrogrid lies in the display method that forms continious unbroken lines, unlike as in other digital displays, combined with choosing between two different time telling methods with the same graphics.
UPDATE: Binary Mode explained
