Learn how to set the moon phase on your Natty Boh Moon 34 watch. Step-by-step guide for Polar White and Mother of Pearl models.
Quick Answer
To set the moon phase on your Natty Boh Moon 34, pull the crown to the first position and turn it clockwise until the moon disc shows the correct lunar phase. Always set the moon phase after the time and date to avoid damaging the movement.
Why Setting the Moon Phase Matters
The moon phase complication tracks the lunar cycle, adding a poetic touch to your wrist. On the Natty Boh Moon 34, the moon phase is displayed through a small aperture on the dial. Setting it correctly ensures the watch shows the right phase for days or weeks without adjustment.
The moon phase is not a simple date display — it requires a separate setting process. Doing it wrong can misalign the moon disc, making the phase appear off by several days.
What You Need Before Starting
You only need the watch itself and a reference for the current moon phase (a quick online search or a moon phase app works). The Natty Boh Moon 34 uses a Swiss Quartz movement, so no winding is required. The crown has two positions: position 0 (screwed down), position 1 (date/moon phase), and position 2 (time setting).
Step-by-Step: Setting the Moon Phase
- 1. Check the Current Moon Phase: Look up today's moon phase using a reliable source (e.g., timeanddate.com or a moon phase app). Note whether the moon is new, waxing, full, or waning. Setting the moon phase without knowing the current phase will result in an incorrect display.
- 2. Pull the Crown to Position 1: Unscrew the crown (if applicable) and pull it out to the first click. This is the date and moon phase setting position. Do not pull to the second click (time setting) yet. Pulling to the second click will change the time, which can interfere with the date change mechanism if done at the wrong time of day.
- 3. Turn the Crown Clockwise: Rotate the crown clockwise (toward you) to advance the moon disc. Each full rotation typically advances the moon phase by one day. Continue until the moon disc shows the correct phase relative to the reference you checked. Turning counterclockwise may not move the moon disc or could damage the mechanism. Always turn clockwise.
- 4. Set the Time and Date First (If Needed): If you also need to set the time or date, do that before setting the moon phase. Pull the crown to position 2 to set the time, then push back to position 1 to set the date. Only after both are correct, proceed to step 3 for the moon phase. Setting the moon phase before the time/date can cause the moon disc to advance incorrectly when you later adjust the time.
- 5. Push the Crown Back and Screw Down: Once the moon phase is correct, push the crown back to position 0. If your watch has a screw-down crown, gently screw it clockwise until snug. Do not overtighten. Leaving the crown unscrewed can allow moisture or dust to enter the case. A snug, not tight, screw-down is sufficient.
About the Natty Boh Moon 34
- Natty Boh Moon 34 - Polar White: Limited to only 100 timepieces in the Polar White color way, powered by a Swiss Quartz movement with a moonphase complication, 34mm diameter, 10mm thick. The Swiss Quartz movement ensures accurate timekeeping, and the moonphase complication adds a classic, romantic feature that requires proper setting to function correctly.
Natty Boh Moon 34 - Polar White - Natty Boh Moon 34 - Mother Of Pearl: Also part of the Natty Boh Moon 34 collection, the Mother of Pearl dial variant shares the same Swiss Quartz movement and moonphase complication. Whether you choose Polar White or Mother of Pearl, the moon phase setting procedure is identical, so this guide works for both models.
