IWC Fliegerchronograph Day and Date will not synchronize.

mcdevito75 here, Over Forty (40) years ago, watch manufactures added, to some of their ANALOG (wind up) and almost all of their DIGITAL (button display) watches the FEATURE of the, MONTH or DAY of the WEEK and the DATE, not only was the time of day available but also the DATE which you no longer had to go searching for, it was readily available on your wrist. The PROBLEM came with SETTING the CORRECT MONTH or DAY of the week and the DATE as some MONTHS HAD 31 DAYS rather than 30 DAYS, this meant you had to CYCLE your watch at least 62 times to get to the CORRECT DATE and mant times, when you finally did reach the CORRECT DATE, the day of the week was off, meaning more CYCLES thru the 24 hours.-------- HERE is the EASY way to SET the MONTH or DAY / DATE on your QUARTZ / MECHANICAL (STEM) watch without haveing to go thru the 24 hour cycle so many, many times. Not only is this, WEAR on your fingers, you can also damage your watch with some many cycles of the 24 hours to SET the correct MONTH or DAY / DATE. ------ HERE ARE THE BASICS,---------- Your ANALOG or STEM watch either QUARTZ or MECHANICAL should have a TWO (2) position STEM we are only familiar with the ONE (1) position we use to set the TIME, there should be TWO (2) positions to the STEM. First pull out the STEM to adjust the MONTH or DAY depending on your watches display, if your watch DISPLAYs the DAY of the week, set the DAY to one (1) DAY before the DAY you want, don"t worry about the DATE (number) yet. Once you have the MONTH or DAY set, push the STEM back into the watch, NOW with a finger nail just under the STEM (usually from the back of the stem as there is more room) gently lift the STEM to it"s first position, It may take some practice so be patient, once the STEM is in it"s first position you should be able to turn the STEM to adjust the DATE (number), if so Adust the DATE (number) to ONE (1) DATE before the DATE you want, This way your watch will be adjusted to change the DAY / DATE at the correct time. Once you have the DATE (number) adjusted to ONE (1) DATE before the DATE you want, push the STEM back into the watch, NOW pull the STEM out to adjust the time, go thru the 24 hour cycle to adjust to the correct DAY DATE (number) and time of day.------------ Your QUARTZ or MECHANICAL (stem) watch is now adjusted to the correct DAY / DATE and will change at the correct hour which is generally 12--1 AM.
