Both tell the time, but a clock stays in one place while a watch is worn on the wrist or carried.
Side-by-side comparison
"Clock" is a wall clock, table clock, or tower clock: fixed in one place. You do not carry it with you; it is installed somewhere.
The clock on the wall says it is 3 pm.
My alarm clock woke me up at 6.
Big Ben is one of the most famous clocks in the world.
"Watch" is a wristwatch or pocket watch: you wear or carry it with you. It is also the verb meaning to observe something attentively.
She checked her watch and realized she was late.
He got a beautiful gold watch for his birthday.
I always wear a watch on my left wrist.
Common mistake
"Look at your clock" when the person is wearing it on their wrist is wrong. If they wear it, it is a "watch". "Clock" is for fixed timepieces: wall clocks, desk clocks, or tower clocks.
Trick to remember it
- •"Clock" = fixed on a wall or desk.
- •"Watch" = worn on the wrist (wrist + watch = wristwatch).
- •Can you hang it on a wall? Clock.
- •Do you wear it on your wrist? Watch.
Quick rule
- •"Clock" = fixed timepiece (wall, desk, tower).
- •"Watch" = timepiece you wear (wrist, pocket).
Did you know?
The verb "watch" (to observe) and the noun "watch" (wristwatch) are the same word. Early pocket watches required you to "watch" (observe) them closely to read the time. "O'clock" comes from "of the clock": "at 3 of the clock" shortened to "3 o'clock". And "clockwise" refers to the direction clock hands move, before clocks, the reference direction was the path of the sun across the sky.
