Craftsmanship. A big reason why the clocks are so expensive, and also why they're so coveted, is because of the talent and craftsmanship that goes into them. A lot of skilled labour goes into making a masterpiece like a grandfather clock.

Wall clocks are the most common type of clock and are commonly used in homes and offices. They can be used purely functionally, making it easy to glance up and check the time from anywhere in the room.
