What is the moon phase?
The moon phase, which reproduces the waxing and waning of the moon on the dial, is one of the most popular mechanisms in watches. Members of the editorial staff of the watch magazine Chronos Japan held a live YouTube broadcast on the subject of moon phases.
In preparation for this broadcast, we asked our readers to fill out a preliminary survey about moon phases. At the same time, we also solicited posts on X (formerly Twitter) using the hashtag "#AutumnWatchesSpeakingOfMoonPhase." This article contains an archive of the broadcast, which was based on questions received in the survey and social media posts.

This livestream will feature models that could not be shown with images, as well as the results of a pre-release survey on "Moon Phase Trends" conducted among webChronos readers. The survey and hashtag submission period was from 9:00 PM on October 23, 2024 to 11:59 PM on October 28.
Which moon phase do you want?

Automatic movement (Cal. 6054.4). 34 jewels. 28,800 vph. Power reserve approximately 72 hours. 18KRG case (diameter 40mm, thickness 10.94mm). Water resistant to 30m. Price: 429 million yen (tax included).
In the survey, readers named the following brands and models (a selection of models that received two or more votes):
・Blancpain "Villeret"
・Blancpain "Fifty Fathoms Bathyscaphe"
・A. Lange & Söhne "Lange 1 Moon Phase"
・Breguet "Classic 7787"
・Glashütte Original "PanoRnineBirth"
・Glashütte Original "PanoMaticLunar"
・IWC "Portugieser Perpetual Calendar"
・IWC "Portofino Hand-Wound Moon Phase"
・Vacheron Constantin "Egérie"
・Omega "Speedmaster Moonphase"
・Orient Star "M45 F7 Mechanical Moon Phase"
・Jaeger-LeCoultre "Master Control Calendar"
What dial would you consider ideal to pair with the moon phase?
The survey yielded the following responses (since it was an open-ended question, some people listed more than one answer, resulting in a total of 81 votes):
Blue: 25 votes
White: 20 votes
Black: 15 votes
Silver: 7 votes
Other: 14 votes
"Other" responses that were not widely mentioned during the live stream included "Blue letters (are good)," "Gray," "Brown," "Green," "Dark colors are good," "It's hard to say," and "Any color is fine." There was also an opinion that "It's not about the color of the dial, but I think the kamaboko-shaped part that represents the crescent of the moon should be black or navy, not silver or gold. With silver, it looks like the full moon is hidden by clouds, not the crescent moon."
During the live broadcast, the Citizen Campanola models mentioned as "models reminiscent of the moon at sunrise" were the Moon Phase Akane and Kokiake.

Quartz movement (Cal. 6324). Accuracy ±20 seconds per month. Battery life approximately 3 years. Stainless steel case (diameter 36mm, thickness 10.1mm). Water resistant for everyday use. Price: 297,000 yen (tax included).

Speaking of moon phases, the Blancpain with the moon with a face is probably the one.
The photo is from 1735. This watch appeared as an important item in the episode of the manga "Gallery Fake" that focused on the moon phase.#Autumn clocks are all about the moon phase pic.twitter.com/YGTo55IoZo— Hopper (@HOPPER_TOKEI) October 25, 2024

Today's watch is an Audemars Piguet with a Matsushita-an strap. The texture of the enamel dial and hands is amazing.
