- lnenad 2y agoI mean, how is this true if he doesn't know which watch is "wronger" and by what margin of error? If it is 2pm and one watch shows 2pm and another 1:30pm the average is worse off than having one watch that shows 1:46pm.
- The_Colonel 2y agoIf you have 2 watches with let's say 5-minute difference, I have a pretty high confidence that the indicated hour is correct. The chance that both watches e.g. broke in the same way is small. I don't think you will necessarily get a higher precision, but your confidence of the indicated time is higher.
