This word clock is certainly a weird idea. Or I should labeled it as “new method” in time reading. You won’t see any numeric character on the clock. Instead, you will see the “It’s about” and on the other separated part, “Five minutes to” and the text will scroll to the related text such as “Three” to show 02:55/14.55.
From the physical design, you will see the clock as Pipe, Cylinder Tube or anything similar. You won’t see any ticking needles. The red mark act as the pointer and it will tells you the line that you need to read to tell the current time.
As its name suggests, Word Clock tells the time in words.
The clock consists of two adjacent rolls, contained in a clear acrylic tube. A red mark indicates the line that should be read to tell the time. The left roll spells out five minute increments of time. The right roll contains the numbers one to twelve, spelled out. The gearing is such that as the minutes turn to “twenty-five minutes to,” the hour roll advances.
Muller and van Dongen applied for a patent in the United States for their “Elongated Clock” in 1982 and the patent was granted in 1984. This design has been a classic ever since.
