How to set up a Tissot quartz moon phase watch
Short answer: Unscrew the crown if it screws down and pull it to II. Turn it backwards until the full moon is centred, then one more notch back for each day since the last full moon. Do this outside 22:00–02:00 on the dial. Set the time at III.

- Turning the wrong way at II sets the date instead of the moon, or the reverse. On these models backwards is the moon.
- Forgetting to screw the crown back down affects water resistance.
