mcdevito75 here, The stem has 2 positions, first adjust the day or month by going thru the 24 hour cycle with the stem. once set, slip a finger nail just ubder the stem and lift carefully this should allow you to change the DATE adjust to 1 date before the date you need, now pull the stem out to adjust date and time of day turn sten the complete 24 hour cycle to achieve the correct date and time of day. Now your watches day and date are set and will change to the next day date on time, around Mid nite 1 --2 AM.

Go to settings. The 3rd one down is to set time and date

Goto the menu-->Settings-->"Time and date"
and there you can set both time and date.

Problem fixed. I removed the battery and allowed the phone to do an auto adjust for time and date when it was turned back on.
Thanks anyway.

On the main menu select Settings, then Time & Date.
Set Time zone updating to Manual.
Then SCROLL down i.e. drag the menu upwards (this is the bit that many don't realise.)
Then you will be able to set the time & date.
