Wristwatch Used

How much energy use digital clock?

I want a real number in milliwatts or microwatts. A voltage and current usage would be good, too. Please link to a spec sheet of a real product. "I think it is probably very low "is not helpful.

They were a little microwatts in the past. Today they are in the broad femtowatt, would not be surprised if in the range attowatt. hope this answers your question correctly
