Moonphase Model LC1048 How do I adjust the moon phase without at the same time changing the date?

for Tissot PR100 Automatic Chronograph with moonphase, minute recorder, hour recorder and seconds subdials, to set the moonphase
there is a sunken button between the chronograph start/stop and the winding crown.
Using a pointed object such as a ballpoint pen, push the sunken pusher gently until the moonphase moves one step, (if you press the pusher completely in, it will also advance the calendar hand, so only press enough to move the moonphase and no more for moonphase adjustment)

You have to pull the winding stem halfway out so that it's not fully extended but not pushed all the way in. then you can turn it to set the date. As for the moon and stars, it's to show the phase of the moon. You just have to wind the arms around until you get the moon in the right position.

May be you need to try harder?

The moon phase is based on the Lunar calendar.

Lunar calendars differ as to which day is the first day of the month. For some lunar calendars, such as the Chinese calendar, the first day of a month is the day when an astronomical new moon appears in a particular time zone. For others, such as some Hindu calendars, each month begins at full moon. Others were based in the past on the first sighting of a lunar crescent such as the Hebrew calendar.

The crown has three positions. The A position is when it’s pushed all the way in. You can’t set anything in this position. The C position is when it’s pulled all the way out. The B position is the click between all the way in and all the way out. My biggest problem is that I read the directions to mean that there were FOUR positions. I didn’t realize A was all the way in. I thought there was three pulled out positions.
To set the day of the week (Sun, Mon, etc.): Pull the crown all the way out (position C) and turn the time to just after midnight. The setting will click to the next day. To advance it an additional day, you don’t have to turn the hands another twenty four hours. You can turn the hands backward to before midnight (you will see the day of the week setting click a little, but not go backwards), then turn the hands past midnight again.
I recommend setting the day of the week setting to YESTERDAY. You’ll see why later.
To set the date: Pull the crown one click out (position B) and turn the crown away from you (clockwise). This will advance the day indicator (it looks like a second hand). To set the month, you have to keep turning until you get past an entire year. There is no separate way to set the month. To make the correct month show, you must keep turning the crown past every day of the year until you get to the correct day.
I recommend setting the date to YESTERDAY. I’ll explain why later.
To set the moon phase: Pull the crown one click out (position B) and turn the crown toward you (counter clockwise). To find out what phase the moon is currently in, here are a couple of websites:

• StarDate Online | Moon Phase Calculator
• U.S. Navy: Phases of the Moon
• Moon Phases :: Calendars

Once again, set it to the moon phase for YESTERDAY.
To set the time: Pull the crown all the way out (position C) and turn the crown either away or towards you to set the time. Keep turning the time away from you (clockwise) until you get past midnight. Once you get past midnight, ALL the settings should change (day of the week, date and moon phase). Now you KNOW you’re on today’s date at just after midnight. Set the correct time and your Luar watch is ready to go!
Review Many of the Swatch enthusiasts were disappointed that the Luar is a battery powered watch instead of an automatic. With a price tag of approximately $450, it’s a little much to expect an automatic with a real moon phase. I’ve talked at length about what I desire in a watch here:

My desires have changed a lot since that day nearly four years ago when I went looking for the perfect

hi i have a Gevril automatic watch and it said in the manual never try setting the watch between 21:00 - 04:00 , that would damage the internal parts

I looked at a picture of the watch. I see the date. the dial that is right below the hands is a moon dial which does the phases of the moon & below that you have a separate second hand. A lot of times on a watch that looks like that if you pull the crown where you set the watch with out half a click it will set the date if you turn it on way and the moon dial if you turn it the other way. To set the moon dial on the watch you need to put it on the full moon when the moon is full again then it will keep up with the phases of the moon. I hope this helps.
