Date is changeing at 6 in the afternoon

Your watch is 12 hours out of step.The date changes ever second rotation of the hour hand.

If you advance the time 12 hours, the date will change at midnight.

You may have to re-set the date.

Pull out to the "winder" to the first click. this is to change the date. The second click is to change the time.

Changing the date - rotating the winder (if you were looking at it) in a clockwise directions changes the major decimal - the number on the left e.g. 0, 1, 2, 3. Rotating anticlockwise changes the lesser decimal - the number on the right e.g. 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

Hope that helps.

The correct time zone setting for Arizona on this watch is YEA (Edmonton International Airport). Hold the adjust button for several seconds until the three code time zone starts flashing, then use the forward/back buttons to select YEA.You need to keep the DST mode off, so press mode once, then the forward button to select off in the DST select screen. From there, you can then press mode to manually adjust each time/date area individually. The final thing that you can adjust is the language, choose ENG for english. Press adjust to keep your settings, and you should be good to go.

Unscrew crown pullout 2 stepsturn hands around till the date changes .this will indicate to you it is midnight .turn ands around to right time.if you are setting this in the afternoon remember to go past the 12.When this is done push winder in 1 step and turn winder clockwise or anti cclocwise and this will let you set day or date. When you finish push winder back in and lock down.

The MTG-900 supports automatic DST which can be activated in the time setting mode.  However, the ROM in the MTG-900 dates from before Congress (in their infinite ability to make mistakes) modified the DST schedule, so, instead of switching at the beginning of April and the end of October (as currently specified), it switches at the end of April and the beginning of October (as previously specified).
I do not believe that there is a way to change the DST scheduling or manually turn DST on or off.  I've resorted to changing the time zone manually and turning off the DST feature.  IOW, I set the timezone to Pacific (LAX) during PST, and, to Mountain (DEN) during PDT.

If DST is set to AUTO,time (DST ON-DST OFF) is corrected automatically when the watch is synchronized.
Synchronization period (Radiocontrol) from 00:00 until 06:00.
If you live in an area where atomic signal cannot be reached by the watch,you have to change DST-NORMAL and vv,manually,by going to WT (World Time) function and when your city (or the closest big one) appears on the display,press and keep pressed for 1-2sec the SET button.
DST mark will appear or disappear,accordingly.

You don't need to set the watch back an hour.  You just need to turn off the automatic DST adjustment.
Hold ADJUST for several seconds.  Then, when DEN starts flashing (or whatever timezone you are set to), hit MODE The display will change to DST flashing at the top and on or auto flashing at the bottom. Click TIME/MEMO or RECEIVE to change on->auto->off.  Once off is flashing at the bottom, hit ADJUST twice and you will be out of DST mode and everything should be fine.

The three buttons are the Chronograph start button (top), Crown (middle), and chronograph reset (bottom).
To set the watch pull the crown out to the first position and turn it until it is on the right time.
To set the date pull the crown out to the second position and rotate until you have the right date.
Be sure that when you set the time that you are in the right AM or PM. DO this by watching when the date turns at the 12:00 position. The date changes at midnight so that would be AM.

hello..this is not abig problem..just a sincronization one...ususlly I set the date around the 12 oclock in the night..the 0 hour..its easier...if you dont want to do this...well..then just count the hours ..remember you have the 24 hours /day..and remember the date is changing in the night around 12 oclock..
for instance...lets say..now you want to set the date..you count the hours until tonight at 12...you put it lets say...with 12 hours back..and wait the change in the midnight..
the easier way is to set it at midnight
oh...by the way..I saw watches which change the date around 2 oclock in the night..but this is a very small %...99% are set to do it at 12..
good luck

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.
