A New Dawn

Humanity stands on the verge of a Space Renaissance, set to transform the future of us all. Monolith is the first toolwatch designed for this new era – your companion for life beyond Earth.

Design philosophy

Developed over 6 years, Monolith is built to withstand the harsh environments of space. Each component is tested against EVA/IVA protocols (Extravehicular and Intravehicular activity) established during the Apollo era, and further developed through modern engineering. Every material and manufacturing process - from gaskets to screws - meet ISO aerospace standards and NASA material guidance. Innovation is pursued not for its own sake, but to deliver the most reliable tool possible.

Built for the harshest environments

Weight to orbit

Escaping Earth’s gravity is expensive: with market rates of ~20,000 USD per kg to the ISS and ~1.3 million USD per kg to the Moon, every gram counts.

Microgravity

Fracturing materials introduce safety risks, as debris is difficult to contain. Basic handling and timekeeping mechanics changes fundamentally.

Radiation

Harsh cosmic radiation can deteriorate coatings/paints, disrupt electrical systems, and flip bits in memory, leading to data corruption, and system failures.

Temperature

Rapid and extreme temperature fluctuations in the range of -120C to +120C during spacewalks.

Pressure

While Earth-bound technologies operate under positive atmospheric pressure, space hardware must also withstand vacuum conditions during spacewalks and risks from material off-gassing.

Visibility

Extreme lighting conditions demand high legibility. From direct solar exposure to deep shadow, contrast is severe and visual cues are unreliable, requiring consistently readable interfaces and markings.

Aircore Chassis

The Monolith chassis is built from Scalmalloy using advanced 3D printing technology, delivering an unmatched combination of strength and lightweight.

Strength of titanium at nearly half the weight. Scalmalloy is an aerospace alloy with an unmatched strength to weight ratio.

Monolithic Dial

Made from layered Aerolight X2 Ceramic sandwiched between precision machined brass, the dial offers unmatched durability and high visibility even in the darkest reaches of space. With no paints or adhesives, the monolithic construction prevents flaking and aging, remaining unaffected by the most extreme conditions for centuries to come.

C-Plane Sapphire

Typically used in high power lab-grade laser systems, C-plane sapphire is a specific crystallographic orientation of sapphire with a hexagonal structure. This orientation gives it exceptional strength and clarity, making the Monolith window highly resistant to both scratches and shattering.

Bridging physical and spiritual realms

A watch is more than a functional tool - it’s a companion. It is therefore ideally suited for a Memory Disc integration, preserving a connection to home for astronauts and serving as a modern-day Rosetta Stone for future generations.

286 languages

In collaboration with UNESCO, we’ve integrated 286 translations of its constitution’s preamble, including numerous rare indigenous languages. It serves as both a linguistic archive and a powerful symbol of humanity’s interconnectedness.

Le Petit Prince

The world-renowned novella by French author Antoine de Saint-Exupéry is a cultural treasure and the most translated non-religious book in history. Engraved in full, the novella carries an enduring message of wonder and optimism.

Art

A curated collection of cultural masterpieces, symbolizing humanity’s creativity and shared heritage. This collection spans various eras and geographies, featuring both well-known cultural treasures and lesser-known artifacts. Each engraving on the Memory Disc has been selected to represent the diversity and richness of human artistic expression.

Voyager Golden Record tribute

Inspired by the original version, this tribute outlines the size and instructions for reading the Memory Disc. Just as the Voyager Golden Record was designed to communicate with potential extraterrestrial life, the Memory Disc includes detailed engravings to ensure its content is understood by future discoverers.
