Setting the date on a wristwatch correctly?

Question

Date changes every 12 hours instead of every 24

Answer 1

you need to reverse it or forward it by 12 hours.

Answer 2

say your watch is set at 7:00, the date counter thinks it is 7pm when it is really 7am on that day. this means 12 hours later the date counter goes to the next day 12 hours too early. so you can turn the clock back 12 hours to get it to show the correct date.

if this does not work try calling a watch repair/jewelry store and see what they recommend since there could be something wrong with the counter itself.
