On my brand new AMW320D-9EV Casio dive watch, I can't get the digital month-date-day funtion to automatically roll over to the next day at mid-night. For some reason, the date changes on me at around 5pm each day. I'm doing something wrong but don't know what.

About watch movements: technical details

Set the right date and year and day will come automatically.

Your watch is 12 hours out of step.

The date changes every second time the hour hand passes 12 O'clock.

Your watches' second pass is at midday instead of midnight, so to make it operate correctly, you need to wind it on 12 hours. The date will then change at midnight.

If the day of the week is incorrect, make sure the date is set correctly. The format on the Casio CA-53W is year first, then month, then day last.

mcdevito75 here, If your Fossil watch has a winding stem it may have 2 positions, gently place a fingernail under the crown and lift as gently as possilble, this should allow you to adjust the date without having to cycle thru the 24 hours to get to the date you want. It may take practise but that first position should be there, Set the date to 1 day before the date you need, then set the watch normally the full 24 hour cycle to get the date you want, this way the watch date will set as suppose to at about mid-night for the next days date.

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.

mcdevito75 here, YES! that"s normal, all Date watches go up to 31, as some months have 31 days, watch makers haven"t come out with a mechanism that will automatically jump the 31 to the 1, well not that I know of, you simply turn the hands another 24 hours from 31 to 1 if the specific month ends with only 30 days.

Press the lower left button and hold it there. It will stop the display cycling mode

mcdevito75 here, The stem has 2 positions, first, set the day to 1 day before the day you need, now, slip a finger nail just under the stem and gently, gently lift the crown to it;s first position, set the DATe to 1 date before the date you need. Push crown back in, now pull crown out to set the date and time of day. Your watch is set and should change around mid nite

thats because analog watches don't know the difference between AM/PM. First reset the time, moving the hour and minute hands another 12 hours will let you know exactly what mode its in (am/pm) first allowing you to set the date correctly.
