The Moon On Your Wrist

For centuries, the moonphase complication has been one of watchmaking’s most poetic expressions of time.

It connects mechanical watchmaking to astronomy itself — tracking the lunar cycle through gears, precision engineering, and motion. Yet despite this deep connection to the moon, almost every moonphase watch shares one thing in common:

The moon displayed on the dial is symbolic.

At Emerton Scott, we wanted to create something more meaningful.

We wanted to take the moon and place it elegantly on your wrist.

Real lunar material from space.

 

The Search for Genuine Lunar Material

Creating a genuine lunar moonphase proved to be vastly more complex than simply sourcing “moon rock.”

Authenticity mattered enormously to us.

If we were going to claim our moonphase contained genuine lunar material, we believed the provenance needed to be fully documented, scientifically recognised, and traceable.

We also wanted to make sure the tone and aesthetic appearance of the material matched with our dial design and overall vision for the Setsuna timepiece.

This led us into the highly specialised world of lunar meteorites and developing relationships with experts in that space.

After an extensive search, we worked with an American company with decades of experience to help us source material from an officially classified lunar meteorite known as Adrar 013.

 

Adrar 013

• Official Classification: Lunar (melt breccia)

• Found: Adrar, Algeria

• Year Purchased: 2023

• Officially Approved: 14 February 2024

• Total Known Mass: 3.15 kg

 

Adrar 013 is officially recognised within the Meteoritical Bulletin database and is classified as a Lunar (melt breccia) meteorite.

This classification is exceptionally rare.

At the time of classification, Adrar 013 became one of only approximately 60 officially approved lunar melt breccia meteorites known.

These meteorites are fragments of the moon itself that were ejected from the lunar surface following ancient impact events before eventually travelling through space and arriving on Earth.

In other words:

The lunar material within our moonphase carries a direct physical connection to the Moon itself.

 

Why Adrar 013 Was Chosen

Finding genuine lunar material was only the beginning.

The far greater challenge was finding the right lunar material.

We spent a significant amount of time researching available specimens, analysing textures, coloration, structural consistency, and long-term suitability for miniature watchmaking applications.

Most lunar meteorites are visually unsuitable for our purposes. Some are too dark, too fragmented, too metallic, or aesthetically inconsistent once reduced to miniature dimensions.

Adrar 013 stood apart.

Its natural grey-toned appearance possessed the exact visual character we were searching for — closely resembling the subtle tonal qualities associated with the moon itself.

The material displayed an organic depth and texture that could not be artificially replicated.

Equally important was provenance.

Every gram of material we could buy had to have:

• Official scientific classification

• Documented ownership history

• Traceable origin records

• Verified authenticity

• Recognised institutional documentation

For us, authenticity without documentation was not enough.

We wanted every customer to know the material used within their watch was genuine, traceable, and historically recorded scientifically.

 

From Lunar Meteorite to Miniature Moon

Transforming raw lunar meteorite into a functional moonphase component presented an entirely new engineering challenge.

The moons within our moonphase complication are extraordinarily small:

• Approximately 3mm in diameter

• Around 0.5mm thick

At this scale, even microscopic inconsistencies become highly visible.

Lunar meteorite is not an industrial material designed for manufacturing. It is ancient extraterrestrial stone formed through violent cosmic processes over billions of years.

Working with it requires an entirely different approach from traditional watch materials.

To achieve the level of consistency required for our watches, we had to develop and invest in a completely new internal production process specifically for shaping genuine lunar material into perfectly formed miniature moons.

This process was created not only to preserve the authenticity of the material, but also to ensure:

• Structural integrity

• Dimensional consistency

• Long-term durability

• Reliable moonphase performance

• Uniform aesthetic quality across each piece

The challenge was balancing natural uniqueness with visual harmony.

Each miniature moon retains its own subtle organic characteristics, while still meeting the precision standards required in fine watchmaking.

 

Why Authenticity Matters

The luxury industry increasingly uses phrases such as “inspired by,” “moon dust,” or “meteorite-style” materials.

We wanted to take a different path.

For us, authenticity matters because provenance matters.

Collectors deserve transparency.

When a watch contains genuine lunar material, we believe the source should be known, documented, and verifiable.

That is why we specifically chose officially classified lunar material with recorded scientific documentation rather than anonymous or unverifiable fragments.

This level of traceability creates confidence not only for today’s owner, but for future collectors decades from now.

 

Creating a Stronger Connection to the Moonphase Complication

The moonphase complication has always represented humanity’s fascination with the night sky.

But incorporating genuine lunar material changes the emotional experience entirely.

The wearer is no longer viewing a symbolic representation of the moon.

They are viewing material that once existed on the lunar surface itself.

This creates a deeper philosophical connection between the complication and what it represents.

The moonphase becomes more than decorative.
It becomes physical and real.

 

Limited by Nature

One of the realities of working with genuine lunar meteorite is scarcity.

Adrar 013 has a total known mass of only 3.15 kilograms, and only a fraction of that material is suitable for our application.

The process of converting raw lunar material into miniature moons also results in unavoidable material loss due to the precision required at such microscopic dimensions.

Because of this, production capacity is naturally limited.

This is not artificial scarcity created through marketing.

It is a direct consequence of using authentic extraterrestrial material in a form small enough to exist within a mechanical watch.

 

A Material Older Than Earth’s Oldest Landscapes

Lunar rocks preserve an ancient history that predates almost every geological surface visible on Earth today.

Untouched by weather, water, or atmospheric erosion for billions of years, lunar material carries a record of cosmic history frozen in time.

There is something profoundly humbling about reducing such material into a component measured in millimetres, only for it to continue its journey on the wrist of its next owner.

 

The Philosophy Behind the Project

This project was never about novelty.

It was about authenticity.

Every decision.

From sourcing officially documented lunar material to developing specialised manufacturing techniques was driven by a desire to create a moonphase complication with genuine meaning behind it.

At Emerton Scott, we believe true luxury is rooted in substance, provenance, and storytelling.

Using genuine lunar material allows each watch to carry not just mechanical complexity, but a tangible connection to something far beyond Earth itself.

For us, that transforms the moonphase from a complication into an experience.
