sorry about the double posting, thought get more response here Hi,guys.

I am having issue with this recently purchased watch - CITIZEN bu0003-02p.
everything seems working except so-called semi-perpetual calendar.
well, it meant to be semi-perpetual so I only need to adjust in leap year once every four years.
however it's not working at all and I need to adjust several times a year when the month is only 30days.

I have followed the instructions several times to reset it, but it's not improving at all.

Just wondering if I did anything wrong at all?

thanks in advance!

If your caliber is 8730 or similar (check the case back), then you were misinformed about the capabilities of your watch. It has no ability to self-adjust for the 5 shorter months in the year- you must do so manually. If it makes you feel any better, most watches are like this!

(From the 8730 instruction manual, page 17:
② The day of month indicated by this watch follows a 31-day cycle.
To advance to the 1st of the next month after a short month (a month
having 30 days or February), pull out the crown to position 1 and turn
it to the left.)
