Analogue display of hours, minutes, seconds and central date,

3) Setting the time

 

To set the watch, unscrew the crown by turning it anti-clockwise (only for watches with a screw-down crown)

 

Crown positions:

1 Screwed-down position (watch running, only for watches

with a screw-down crown)

2 Unscrewed crown position (only for watches with a screw-down crown)

manual winding. Watch running position (watches without a screw-down crown) manual winding.

3 Time setting, seconds stop.

Adjustment knob A: Quick moon phase adjustment

Adjustment knob B: Quick day adjustment

Adjustment knob C: Quick month adjustment

Adjustment knob D: Quick date adjustment

 

4) Setting the date, day, month, moon phase and time.

 

Using the D dial (quick date adjustment), the C dial (quick month adjustment) and the B dial (quick

day adjustment), set the date to one day before the actual date. Then use the A crown to set the

moon phase. Each press corresponds to one day. To set the moon phase exactly, move it to the full moon position,

then, using a calendar, work out how many days have passed since the last full moon and press the crown the

same number of times. Turn the hands clockwise until they pass midnight; the current date will appear,

then set the time; naturally, if the time to be set is in the afternoon, the hands must pass midday.

At this point, the date and time are correctly set.

 

5) Maintenance 

 

• Avoid strong magnetic fields and shocks.
  

• Recommended service interval: every 4–5 years.
