Just found this info and it was news to me so I thought I'd post it up here .
Setting the date
Please note: If the time on your watch is between the hours of 10pm and 2am, its not the best idea to change the date manually. The watch would be in the process of changing the date over and forcing the date to change could damage the date mechanism. Either just wait until after 2am or manually change the time after 2am, then set the date and then go back and readjust the time.
