- Confirm the “No‑Touch” Time Window Most Patek Philippe calendars (annual or perpetual) must not be adjusted between 8 p.m. and 2 a.m.—the calendar wheels are engaged and forcing corrections can break the mechanism.
- Set Your Watch to 6 a.m. Pull the crown to the time‑setting position and rotate until the hands read about 6 o’clock; this ensures you are safely outside the danger zone before using push‑pieces.
- Locate the Corrector Push‑Piece Moon‑phase Pateks use a recessed pusher on the case flank (often at 4 or 8 o’clock). Use only the supplied stylus or a plastic toothpick—metal pins can scratch or slip.
- Know Today’s Lunar AgeFind the current moon age (number of days since the last new moon) on a reputable lunar calendar app or astronomy site. A full cycle is 29 days 12 hours 44 minutes. Example: if the lunar age today is 10 days, count 10 clicks from the “new moon” position.
- Advance the Moon Disc Press the corrector once per lunar day. Each click shifts the moon disc one notch. Stop when the disc shows the correct phase relative to the moon aperture.
- Re‑Synchronize the Date (if applicable) If your model is an annual or perpetual calendar, use the dedicated date corrector to align the day, date and month. Always adjust date before moon‑phase on perpetuals.
- Return the Crown & Test Push the crown back and wind gently. Verify that at midnight the calendar changes smoothly; the moon disc should advance at around 1 a.m.
