- A cog is, properly speaking, the portions of a gear that interlock with other gears, though gears themselves are sometimes called cogs. In either case, gears/cogs are commonly used in old-fashioned analogue clocks.
- A bell is a simple musical instrument that makes a single tone when struck. Some types of clock use a bell to sound off the start of the hour.
