How to change day and date - Casio Atomic-Solar MTG900 Watch

It's a mechanical movement and takes time, to fall into place ,

You are very observant! Timex watches don't have a way to adjust the day.
However, if you turn the hands clockwise you will see the day advance.
So, heres the secret, follow exactly:
1. Turn the hands until the day of the week shows the day before. If today is Wednesday then turn the hands until the watch shows Tuesday
2 Adjust the date to the day before. If today is the 17th then adjust it to the 16th
3. Now pull the crown all the out and and advance the hands until the date changes to the correct date, 17 in this example. This happens at midnight. Continue the movement in a clockwise direction for a few more hours and you should see the day change to the correct day.
4. Now continue to move in a clockwise direction until you have the current time. Remember that your date/day changed at midnight so if the current time is after lunch(noon) you must continue past noon to get to the correct time. If you don't do this correctly your date will change every day at noon instead of midnight.
If you don't succeed the first time, try, try again! Good luck, Michael, Watchmaker to the Stars!

the crown of the watch has two clicks, pull it gently once and you can set the date and day, pull it gently again a second time and you can set the time. The proper way to set the time and date is to set first the day,date late at the actual date, then move the hands around the clock until the date change at 12 oclock this is evening, then moving the hands around until you reach the actual time. By doing so you will set the day, date and time in syn to 24 hrs change.

example: you want to change it to sat 12th 11am
set the day and date to fri 11th
then move the hands around clockwise until the day and date change at 12 oclock continue moving the hands until you reach 11am

mcdevito75 here, Your Bulova watch should have a 2 position crown (winder), carefully lift the crown to it"s first position, this should allow you to change the DAY, once done pull crown out to set the time, keep turning the hans till you get the right DATE (number) now set the correct time and your done.

mcdevito75 here, Your stem has 1 positions to set the date easily without haveing to cycle the watch 60 times. First pull the stem out to set the day, set the day 1 day before the day you want, next, push the crown back in, NOW! Slip a finger nail just under the crown from the back as there is more room, it may take some practice so be patiernt and gently, gently lift the crown to it"s first position, once in it"s first position turn the stem and see the DATE change, set the DATE to 1 DATE before the DATE you want, NOW pull the stem out to set the day date and time of day. Your watch is set and the day date will change on time, a little past mid nite.

Try this: pull out the winding crown to the first click and change the date. Memorize which way the crown turns to do that. Now turn the crown in opposite direction and the day should adjust.
This solution wrks for most of the makes.
If this doesb't work - submit the make, model and all the writings on watch caseback.

if all else fales, you are probably in need of a service.

hi
never change week or date when day is on "sun" or "mon" also never change date or week or day when time is between 9 pm and 5 am.
to change day, move time back and forth between 10 pm and 2 am.
moon will change only after 24 hr round (not during quick day change)
hope this helps

The Skagen watches have  two-step stem; fully pulled out will change the time and partially pulled out will change the date (only goes one way so try turning it counter-clockwise or clockwise - I forget which is correct).  It's easier to find the date length by extending it all the way and then go back toward the case.  It won't change the date if you run it through a 24-hour cycle - you have to do the half-way thing.  Hope this helps.

I have a Seiko Diamatic 780632. To set the day and date, pull the crown once and wind it upwards (away from you) to set the date; winding it downwards (towards you) will set the day. To set the time, you have to pull the crown twice and wind it towards you.
