@_nveu: The largest clock in the world is not just an ordinary clock, but a massive landmark overlooking Mecca. It is located on top of a huge tower in the Abraj Al Bait complex, and its face can be seen from very long distances. It was designed to be an architectural and religious symbol seen by millions of visitors every year. The diameter of the clock face is about 43 meters, a huge size that makes it larger than many famous clocks around the world. Each side of the tower carries a giant clock, so they can be seen from different parts of the city. As for the hands and numerals, they are designed with strong lighting that works at night to remain clear in the sky.
