My calendar is switching 12 noon instead of midnight. i just bought this watch model 2600058 yesterday. how to adjust it>

Time is not set correctly. You set the time as AM instead of PM and vice versa. Use the following manual to set time correctly.

probably because you have it set to 12 pm midnight and not 12 noon so at 12 noon it is actually midnight when the date will change
reset the time of the day to am or pm and any pm settings will change the date at 12 midnight.

Hi.
I take it that your watch changes date at 12 noon, instead of 12 midnight.
If so change the time of your watch 12 hours, so it reads the same time, but instead of am, it is pm, or visa versa. Analog watches do not have a 24 hour time setting.

Your watch is 12 hours out of step. (The date changes every second revolution of the hour hand.)

Wind your watch forward 12 hours, (you may have to reset the date) and it will then change around midnight.

Simply advance hands 12 hours forwards (clockwise). Just pull out crown to the time setting position and turn the watch hands forwards if the date is changing before midnight. If the date is changing after midnight - turn the hands 12 hours backwards. Don't do this when the actual time is between 10pm - 2am.

Hello,
This is because you have reversed am with pm.
Set your watch 12 hours back and the problem should be solved.
You might want to wait till midnight or noon to check it's fine.

Note: if you see the day shows the previous day rather than the present day, you have to set the clock 24h ahead.
Problem solved!

Wind the hands forward 12 hours.

Your watch thinks your noon is midnight.

Wind the hands forward 12 hours and the date change will be at midnight. You will have to re-set the date if it gains a day when doing this.

Mechanically operated date changes occur at 12 O'clock. If your watch thinks it is midnight when it is noon then it will change date.

The solution is to wind your watch on 12 hours.

This is an analog watch.

Pull the set stem to the set position and advance 12 hours.

Hope this tip helps.
