Amanico's insightful review of the Arnold & Son Luna Magna in platinum, featuring both aventurine and meteorite dials, offers a deep dive into a timepiece that pushes the boundaries of traditional moon phase complications. His detailed examination of the case, dial, and movement highlights why this model stands out in high horology. This article explores the nuances of its design and the community's reactions to its unique aesthetic and technical prowess.


Arnold and Son is just an incredible brand. The more I see some of their creations, the more I love the brand. 

The Luna Magna ( Big moon, in latin ) is an awesome creation, or should I call it Creature. Launched in 2021 in rose gold or in platinum with an aventurine crystal, Arnold and Son came in 2022 with another platinum version, showing a meteorite and an opal dial. 

These are these two platinum versions we'll see, now. 

1/ The Case: As we said, made in platinum 950, the case is huge: 44 mm and thick:15, 90 mm, but the height included the super domed sapphire glass which has to protect the prominent moon. 


It has a classic shape, like if the brand wanted us to focus on the most important part of this watch, the dial. The crown is well integrated and lovely. 

2/ The Dial is the Soul, the raison d'être of this watch. 

Indeed, there is no other watch like this one. Its huge spherical moon ( 12 mm! ) is as romantic as it is spectacular showing its visible and dark side. The visible side is made of marble, while the dark side is made of aventurine crystal which we also find for the main dial. The dial dedicated to Time is in mother of pearl. 


The Meteorite version is even more special! Its main dial is made in Meteorite, surrounding the dial dedicated to Time in Opal and the spherical moon in meteorite ( dark side ) and in opal (visible side ). AND, if it was not enough, the dial dedicated to Time and the visible part of the moon receive a layer of Superluminova which literally shine in the dark. Poetry at its best. 


The meteorite parts have a sand colored pvd.

3/ The movement is the Cal A&S 1021, superbly decorated and finished, with " Soleillé " Côtes de Genève radiating from the center occupied by the second and more accurate moon phase, chamfered screws, polished heads, circular graining, well, an ode to fine horology. 



It is big ( 37, 6 mm ) and thick if we include the moon ( 12 mm ) but quite thin without ( 4, 75 mm ) and offers a good power reserve of 90 hours. To be complete, it beats at the pace of 21, 600 alternances per hour. 


As for the moon phase, it is accurate to one day each 122 years, which is in the normality. Some brands did better, here, with one day each 3500 years, but who will be there to witness that kind of accuracy?  


Both platinum versions are limited to 28 pieces and there is a gap of around 15, 000 Euros between the Aventurine and the Meteorite platinum versions, the meteorite being the most expensive of these two. 


I must confess I am totally in love with the Luna Magna, a real coup de coeur, a strong love affair. The funny thing is that I am not a huge fan of moon phases when they are not coupled to a perpetual calendar, because the setting is generally fastidious. You have to go to a site which is dedicated to moon phases, then you have to set it generally through a pusher.  

BUT here, I am totally under the charm. The concept, the design, and the fact that you can set the moon phase through the crown are convincing me. 

The big question is which one to get? 

The aventurine version is sumptuous: You are submerged in a starry sky, you are smitten by the spherical moon, the mother of pearl dial dedicated to the Time is gorgeous, you are living a dream.


The meteorite dial is another evocation of space. I am a huge fan of meteorite dials, so this is a plus for me. But the real PLUS is the fact that the opal dial dedicated to Time and the visible side of the moon are luminous... 



Isn't that a delicious dilemma to have? 

Looking forward to reading your comments and thoughts,

Best,

Nicolas

One of the many beautiful creations from Arnold & Son. For me one of the most interesting high horology brands currently on the market. If I would have to choose for the Luna Magna I would probably go with the aventurine dial.

Would love to see any version in person. I think though that my preference here would be the aventurine dial. I'm not exactly sure why, but even though meteorite dials are my favorite I'm still of the opinion no one has managed to surpass Omega in their execution........ Thanks for the write-up Nico!!

For me the size would be a limitation. If I had to pick the aventurine matches the sky theme, however, this meteorite version is a looker as well!

...and except for the considerable size, the color scheme makes it pretty subtle. The glow of the dial and moon is really fantastic!

And it's this: most all moon phase watches ignore the fact that the gibbous and quarter phases can not be displayed due to the design and movement of the complication. I know that is pretty picky but it just seems like every designer has decided "well there's nothing we can do about it so it is what it is". That's not a very common attitude toward design in a world of chain and fusee and tourbillions of all varieties. So I'm curious: has ANYONE ever designed a moon phase that displays ALL phases

That's what actually makes the difference to my eyes here!!
