The date on my Seiko SWZ054 watch has the correct date but wrong day. How do I fix?

You can not set the date..it MUST be returned to Seiko for repair. A perpetual calendar watch does not lose the date if it does something is wrong. Seiko will repair for you.

The crown ( the winder as used to be) will pull out one ,two, or three stops. Each stop does somthing different.e.g. 1 - hands, 2 - day, 3 - date. Sometimes, the second stop will do two functions - turn one way for day and the other for date.

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.

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.

To sync the correct 12 hour with your day you need to set the date to the day before (if today is Wed 21, then make sure the day window reads Tues 20). Then spin the analog hands until the the date window turns to Wed 21. At this point your watch is reading 12 AM (midnight). Then keep turning to set the correct time. If it is 9 am then stop the hands the first time you hit the 9 marker. If it is 9pm, then keep turning until the SECOND TIME your hour hand meets the 9 marker. This is now set for 9 pm. The day (Mon thru Sun) sometimes needs to be set seperately from the day; it may take a couple of tries but use the directions above and patience and you will achieve your goal.
That's how you do it. If you need more clarification let me know.

If you pull out the stem 1/2 way, you set the date one direction, and the day the other. If you pull it out all the way, it moves the hands and sets the time.

Your Seiko has two pulls,first pull for DAY / DATE,and the second pull for the hour and minute.Just do the first pull then wind it clockwise for DAY and the counter clockwise for DATE.Feel free to ask whatever the result...

Hope this may help;
