Wristwatch Atomic

how small are atomic clocks?

i mean real atomic clocks, not the radio kind that just pick up time from a real atomic clock. can they put one into a wristwatch? would it be bulkier? do they lose accuracy? how expensive are they? do they take up a lot of power?

They are very large and very expensive.

They are not actually clocks, just an oscillator that outputs a very stable frequency that can be compared to other frequencies or used as a time base for time measurements.
