Have you ever heard of the mechanism known as the "moon phase"?
I think this is a mechanism that any watch enthusiast has seen at least once.
And I think he was fascinated by what he saw.
I have to admit that I really love the design of the Moon Phase and am fascinated by its beauty.
This time, I would like to share with you the beauty of moon phase watches by looking at the designs of each manufacturer.
What is "Moon Phase"?
A simple explanation of the moon phases
[ Mechanism that displays the phases of the moon on the dial ]
It will be.
The moon phase, a complex mechanism among mechanical watches, is a function that allows you to enjoy the changing phases of the moon and feel the romance of the heavens.
The word "moon phase" means "lunar phase" and refers to the shape of the moon that can be seen with the naked eye when looking up at the night sky. Some easy-to-understand examples include the full moon, new moon, crescent moon, first quarter moon, and last quarter moon.
Basically, one lunar cycle from one new moon to the next is called a synodic moon, and this cycle is set to be about 29.5 days. Due to the movements and relationships of the moon, earth, and sun, the exact range is about 29.2 to 29.8 days, but the average number is used to set the cycle at about 29.5 days.
The creator of this was the well-known genius watchmaker Abraham-Louis Breguet. It is also known that Abraham-Louis Breguet was the first to feature the moon phase in a pocket watch.
Attractive designs from each manufacturer
Now, I would like to introduce some wonderfully designed "moon phase" watches from each manufacturer.
①Patek Philippe
The first one we will introduce is the "Moon Phase" from Patek Philippe, one of the three great watches in the world. It is often equipped with a complex mechanism and has many attractive models.
In this article, we will introduce the model...
I own it lol
・Annual Calendar Moon Phase Ref.5146G-010
I will introduce this model from my personal point of view.
Its precision is outstanding, boasting an ultra-high accuracy of only one day in 122 years. As expected from Patek Philippe. The waxing and waning moon shining in the dark blue night sky is a beautiful design that will captivate anyone who sees it.
②Breguet
The "Moon Phase" created by the genius watchmaker "Abraham Louis Breguet" is truly a first-class product. The brand has created many innovative technologies in the watch industry, and has created many other complicated mechanisms such as the tourbillon and perpetual calendar in addition to the moon phase.
・Classic Moon Phase Ref.7787BR/12/9V6
The face of the moon on Breguet's Moon Phase is so endearing. The three-dimensionally engraved moon disc shows Breguet's attention to detail. The delicate and beautiful guilloche engraving on the dial and the accent blue steel hands work in harmony with the night sky of the Moon Phase, creating a wonderful harmony.
3. A. Lange & Söhne
A. Lange & Söhne is a prestigious German watch manufacturer that boasts some of the most technically advanced watchmaking techniques in the world.
A. Lange & Söhne watches, with their noble image and beauty, are so highly rated that they are even compared to Patek Philippe, known as the watch of the highest order. A. Lange & Söhne's moon phase display reproduces the lunar orbit with the highest level of precision, and once the moon phase is set accurately, the error is only one day in 122 years, proving the high level of their technology.
・Lange 1 Moon Phase 18KWG Ref.192.029
In 2017, 15 years after its release, a successor to the "Ref.192.029" equipped with a newly developed hand-wound movement [Cal. L121.3] was released. In addition to the "moon phase", it also has a new day/night display, and the design that does not interfere with the dial design at all has been highly praised. The color tone of the sky changes from light blue during the day to dark blue at night as the day progresses.
The jet black dial features a blue night sky and moon, giving the watch a chic and sophisticated design that exudes adult sexiness. 
④Omega
When talking about the Moon Phase, this brand cannot be left out. The Omega Speedmaster is the only watch in the world to have reached the moon, and has established an absolute position as a legendary moonwatch. The moon depicted in Omega's Moon Phase is so accurate that it is said to be as if you are looking at the real moon.
・Speedmaster Moonwatch Co-Axial Master Chronometer Moonphase Chronograph Ref.304.33.44.52.03.001
Equipped with OMEGA's new movement [Cal. 9904] that boasts magnetic resistance of 15,000 gauss, this is the world's first Master Chronometer certified model approved by the Swiss Federal Institute of Metrology "METAS."
The moon disc is simply stunning. The moon, created using special micro-machining techniques on the metallic crystal disc, is so detailed that it even depicts the footprints of an astronaut. As a fan of moon phases, I was really tempted to buy it (laughs). It's a design that I think is simply cool.
summary
What did you think of the romantic "Moon Phase"?
If you don't have one, I bet you're starting to want one now! (laughs)
The moon phase, which depicts the night sky and moon that we suddenly look up at on the face of a watch, is a wonderful complex mechanism that can captivate people's hearts.
We hope that after reading this article, you will become interested in the moon phase and find new enjoyment in your luxury watch life.
see you!
