Learn how to set and enjoy the moonphase complication on your Natty Boh Moon Vintage Silver. This guide covers the key features of this limited-edition timepiece.
Quick Answer
To set the moonphase on your Natty Boh Moon Vintage Silver, gently press the recessed pusher on the case side with a toothpick or similar tool, advancing the moon disc one day per press until the moon aligns with the correct lunar date.
Understanding Your Vintage Silver Moonphase
The Natty Boh Moon Vintage Silver is a limited edition of only 100 timepieces, blending vintage aesthetics with Baltimore pride. Its Swiss Quartz movement powers both the timekeeping and the moonphase complication, which displays the current phase of the moon in a subdial. The 40mm case and 10mm thickness make it a comfortable fit for most wrists.
The moonphase complication is independent of the time-setting crown, so you can adjust the moon disc without affecting the hour and minute hands. This is useful if the watch has been sitting unworn for a few days and the moonphase display is out of sync.
When to Adjust the Moonphase
You'll need to set the moonphase after the watch has stopped for an extended period, or when you want to align it with the actual lunar cycle. The moonphase is accurate to within one day per month, so occasional adjustments are normal. Avoid adjusting the moonphase between 9 PM and 3 AM, as the movement's date-change mechanism may be engaged.
How to Set the Moonphase on Your Natty Boh Moon Vintage Silver
- Find the Correct Lunar Date: Check an online lunar calendar or a moonphase app to determine the current moon phase. Count the number of days since the last new moon (day 0). For example, if the last new moon was 5 days ago, the moon is 5 days old. A common mistake is counting from the full moon instead of the new moon. Always start from the new moon (day 0).
- Locate the Moonphase Pusher: On the case side, usually near the 2 o'clock or 4 o'clock position, you'll find a small recessed pusher. Use a toothpick, a wooden cocktail stick, or the tip of a spring bar tool to press it. Do not use a metal pin that could scratch the case. The pusher is recessed to prevent accidental presses. Press gently; you'll feel a slight click as the moon disc advances.
- Advance the Moon Disc: Press the pusher once for each day since the last new moon. Each press advances the moon disc by one day. The moonphase subdial shows the moon's current phase—a full moon at the top, new moon at the bottom. Continue pressing until the moon is in the correct position. If you overshoot, you cannot reverse the disc. Continue pressing through a full cycle (29.5 days) to return to the correct day. It's better to press slowly and check your progress.
- Set the Time First (If Needed): If the watch has stopped, pull the crown out to the time-setting position and set the hour and minute hands to the current time. Ensure AM/PM is correct by advancing past 12:00 and noting if the date changes. Then push the crown back in. Setting the time incorrectly (e.g., AM instead of PM) can cause the moonphase to appear off by 12 hours. Double-check the 24-hour cycle.
- Final Check and Wear: After setting the moonphase and time, give the watch a gentle shake to start the quartz movement. The second hand should begin ticking. Wear the watch or store it in a watch winder to keep the movement running. If the watch stops again, it may need a new battery. Quartz movements typically last 1-2 years per battery.
