Louis Moinet presents COSMOPOLIS, a unique timepiece honored with a GUINNESS WORLD RECORDS™ title for “the most meteorite inserts in a watch”.


It boasts twelve meteorite fragments creating a unique and fascinating constellation. In the centre is the rarest and most captivating stone of all, a lunar meteorite. One of these outstanding fragments, a black chondrite, is located in the back of the tourbillon cage, the beating heart of the mechanism.


Ten other special fragments have been carefully disposed, each on its own base that is discreetly attached to dark-grey, brushed dial.


The Louis Moinet COSMOPOLIS watch also boasts an off-centre tourbillon in the subdial at 6 o’clock as well as two centrally placed gold hands for displaying the hours and minutes.

Visible through the sapphire crystal case-back, the hand-wound movement with two barrel springs in  the “volte-face” configuration provides an impressive ninety-six hours of power reserve.

It comes in an 18-ct, 5N rose-gold case with a diameter of forty millimetres. The lines are fluid and taut at the same time.


The highly technical sapphire crystal dome reveals the many fascinating facets of the meteorite fragments below. As for the open-worked lugs, they emphasise the smooth integration of the bracelet.

COSMOPOLIS meteorites description

1. Lunar meteorite, Dhofar 461

Dhofar 461 is an extremely rare specimen of lunar meteorite, characterised by a white-speckled interior. There are currently only 300 recorded lunar meteorites, all of which have been ejected from the Moon during the past 20 million years.

On their way to Earth, some of them orbited the sun first before entering Earth’s orbit and atmosphere, where they turn into shooting stars. Their lunar origin has been confirmed by rigorous mineralogical comparisons, their chemical isotopic composition, and with samples collected during the Apollo missions to the Moon. Origin: Moon, Found near Dhofar, Oman.

2. Martian meteorite, Dhofar 1674

Dhofar 1674 is one of the rarest Martian meteorites. It has an extremely special greenish texture. Like most meteorites, Dhofar 1674 was found in the desert, where its blackened exterior contrasts sharply with the surrounding sand. To date, fewer than 300 Martian meteorites have been identified worldwide. This meteorite costs more per gram than gold and platinum combined. Origin: Mars. Found near Dhofar, Oman.

3. Allende meteorite

The Allende is the most studied meteorite in history. In fact, it has been dubbed the “Rosetta Stone” for the wealth of information it has provided on the formation of the solar system. It is estimated to be 4.567 billion years old and thereby the oldest rock in the solar system. Origin: Meteorite shower. Found in Mexico.

4. Erg Chechmeteorite

Erg Chech comes from a volcanic rock and is the oldest magmatic rock known to date. It originated from a protoplanet that has since disappeared, and it is older than the Earth itself.

After a journey of more than 4 billion years, it landed about a hundred years ago in southern Algeria, in the Erg Chech sea of sand, whence its name. Among the 65,000 recorded meteorites in the world, none share its unique composition. It has an especially stunning appearance that combines green and brown hues and a surface look brought about by a lava flow. Origin: Asteroid. Found in Algeria.

5. Jbilet Winselman meteorite

This mysterious Jbilet Winselwan meteorite contains traces of amino acids, that are probably the first known traces of life in the cosmos. Origin: Asteroid. Found in Morocco, in the Western Sahara Desert.

6. Isheyevo meteorite

The Isheyevo meteorite is a carbonaceous chondrite containing a beautiful sequence of fine layers. Origin: Asteroid. Found in Russia.

7. Aletai (Armanty) meteorite

This meteorite used to be known as Armanty, but is now known under the name Aletai. It is composed of a natural and extraterrestrial mix of iron and nickel. It comes from the heart of an asteroid weighing over one-hundred tons. Origin: Asteroid. Found in China.

8. Aguas Zarcas meteorite

The Arguas Zarcas meteorite is part of a meteorite shower that fell in a rainforest in central Costa Rica on April 23, 2019. Origin: Meteorite shower. Found in Costa Rica.

9. Gibeon meteorite

The Gibeon meteorite landed in Namibia in prehistoric times. It was named after the nearest city. It is famous for the distinctive Widmanstätten pattern, which is typical for extraterrestrial ferrous rocks. Origin: Asteroid. Found in Namibia.

10. Toluca meteorite

This meteorite probably struck Earth over ten millennia ago. For centuries, Mexicans living near meteorites have used them as a source of metal for various tools. The Toluca meteorite fragments were discovered by the conquistadores in 1776. Origin: Asteroid. Found in Mexico.

11. Sahara 97093 meteorite

This extremely rare Enstatite EH3 meteorite features microdiamonds of interstellar origin. They are formed in the heart of stars that exploded and became supernovas. Origin: Asteroid. Found in the Sahara Desert.

12. Black L5 chondrite meteorite

This black chondrite was formed as the result of a gigantic impact in space between two asteroids. Chondrites are considered the first elements that go on to become planets. Origin: Asteroid. Found in the Sahara Desert.
