Seiko Diamatic Day Date Automatic Watch No: 219050

Main cause would be that the date gear teeth have been stripped. This is done by setting the date whilst the hands are trying to change the date themselves (between 10pm and 2am). Always adjust the date with the hands around 6.0clock. You will need to return your watch to where you bought it for repair I'm afraid.

Seiko watches from this period should have a setting stem that pull out half-way and fully. Pulling the stem out fully permits you to set the time. Pulling the stem out half-way should let you set the date by moving the crown forward/clockwise and set the day of the week by moving the crown backward/counterclockwise.

However, for this to work correctly, the watch must have the correct set stem. I have worked with a number of watches, including Seikos, where a generic stem was substituted after someone accidentally pulled out the crown and stem (Seiko replacement parts can be tough to find in the U.S., especially for discontinued models). If an incorrect stem has been installed, the day/date setting procedure I've just described may no longer work correctly. At that point, setting the date involves advancing the hands to get to the right date; day of the week may not be able to be set at all.

Good luck!

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.

Hello,

Seiko watches are a popular accessory for both men and women. The history of Seiko watches goes back to 1881 long time ago, when the company that was to become Seiko began. From the beginning, the method to set a Seiko watch has been designed to be a simple process.

The following are the steps to set a Seiko watch for the time, day and date function, and for setting the chronograph on an analog watch.

Set the Time:

• THE CROWN

Pull the button on the side of the watch carefully, the crown, out to its most extended position. You will need to unlock the crown if your watch has a locking crown. To unlock, turn the crown counter clockwise. While the crown is pulled out in the setting position, the watch will cease functioning.

• 12 O'CLOCK POSITION

Turn the crown clockwise to move the hands of the watch past the 12 o'clock position on the dial. The day and date will change to indicate AM setting but will not change for PM setting. It is recommended that you set a Seiko watch in the morning for instant day and date setting; however,this can be done manually.

• FINISH

To finish setting the time, simply push the crown until it is flush with the side of the watch.

Good luck and thanks for using fixya.

mcdevfito75 here"s how to change the day and date on your vintage Seiko watch, Pull the stem out to the set position and simply turn the stem (winder) every second time around to the 1--2 3 O"oClock position the day will chage, once you get the day push in the stem in all the way, NOW with your fingernail just under the stem (winder) gently lift the stem up to it"s first notch or position, with the stem at this first notch or position, you can turn the stem and the hands won"t move but the date(number) will change, simply go to the correct number / date and your done, push the stem back in a your ready to go.

mcdevito75 here, The stem should have 2 positions to set the DATE without haveing to cycle the watch 60 times. Slip a finger nail just under the crown and gently, gently lift the crown to it's first position, it may take practice so be patient, once in it"s first position you can easily change the DATE, change it to 1 DATE before the DATE you want. NOW! push the stem back in and then pull it out to set the proper DATE and time of day, your watch is set and will change on time, around Mid Nite.

Try this solution I posted earlier for a similar problem.
Put stem into "set hands" position and adjust hands to the 12:00 position. Day and date should advance at or close to that time.
If you pass 12:00 and there's no change continue rotating another 12 hours (to twelve o'clock again) and they should advance. Once you've found that there's midnight.So say it's now 4:00pm you would need to rotate the hands around the dial again so they pass 12:00 once more (12:00 midday) then four hours more to 4:00.
To set the day/date you can set the crown (winder) to the first position (second posn is "set hands) and rotate winder
eithr clockwise or anticlockwise. Once you discover which direction advances the date and day ring just set it to the correct day/language and date you want then press the crown home.
Hope this solves your problem.

I don't know this watch specifically but typically the following applies:
To set the day/date you set the crown (winder) to the first position (second posn is "set hands) i.e. pull out one stop, and rotate winder eithr clockwise or anticlockwise. Once you discover which direction advances the date and day ring just set it to the correct day/language and date you want then press the crown home.

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.
