That will depend on the kind of wrist watch you are using friend...
But considering the fact that a single battery may run for an year or two without replacement. It should be extermely small.
You can calculate it grossly:
1. Check the mAhour rating of the battery being used. say x mAh
2. Check how many days, the battery runs with the watch, say y hours.
3. So x/y mA is the curent consumption.
4. Multiply that with the voltage rating of the battery.
5. Wholla...you have the power consumption of the watch.Are you sure? This action cannot be undone. -

CR2032 is most commonly used in digital wrist watches. It's 1.5V and 230mAh. They work for more than 5 years. Yeah ! they do.
So lets say 50,000 hours. So for 1 hr its should be approx 8microWattAre you sure? This action cannot be undone.
