Day is not changing correctly, getting stuck - Omega Speedmaster 3520 wristwatch

Pull the stem out to the time set level. Turn the hand around until the date change. Now push the stem back in, pull to date set level and change to current date. Now the watch is at midnight for that current date. Note you can set to current time of day. The Watch will automatically change to correct date for next day at midnight as it should.

The date on this watch is shown by the hand on the dial with Sunday written on it. If you read the date dial starting from the top on Sunday there are 6 lines on the face indicating the other 6 days of the week. Therefore your watch is currently showing it is Friday. The "SUN" always shows because it is not like a normal watch. It is the hand on the dial that shows the day.

To change the hand on the day dial you must wind the main knob (LHS) clockwise to move it. To advance it 1 day you must wind the clock around the face twice ie 24hrs and the day pointer will move forward one day. Do this till you get the pointer onto the correct day.
Hope this helps!

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!

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.

hi,
first you kepp the day and date set yesterday's , for example today is 31st and monday so you set 30th and sunday , now keep rolling time by key till day and date has complitaly changed,remind that do not roll anty clock, it may be damages to your watch,now when you get change day and date its a midnight of 31st and monday, now set the time and get started ,

On some analog Timex watches with a day/date window there are only two "pull-out" positions on the stem, one for changing the date and one for the time. To change the day you need to pull the stem all the way out and crank the hands through 24 hour periods until you get the day correct. Be sure that you have the correct AM/PM setting (if you are setting the watch after noon you need to advance the hands another 12 hours so that the day changes at midnight)

Turning it backwards didn't work on my watch. I ended up winding the time ahead several days worth to show the right day of the week (being careful to turn it to the correct 9 o'clock of the day, for me is was the first for morning.) Then I could go ahead and change the date using the first click postition of the stem.

I see that light bulb going off and you whispering "why, of course!"

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.
