New airlock crown update for Monolith🚀 We decided to design around a robust crown that can be used in any condition as opposed to a screw down system. In most cases, popping out a crown or winding a watch under water would cause the movement to get completely flooded. Our airlock crown is currently passing 10ATM crown in or crown out, and allowing it to be wound or set while fully submerged. Further tests still need to be performed but initial data is great. We also maxed out our pressure testing machine at 570m with no issue, almost double the worlds deepest scuba dive on open circuit (332m by Ahmed Gabr) Already overkill but cool to know it can exceed the extremes of human exploration.

Worth noting the design must also handle negative pressure as seen in the vacuum of space, where the watch has 1ATM internally from being assembled on earth, and then being exposed to a 0ATM (vacuum) environment of space. 🛰️

T-07: Airlock Crown🛸

New article is live!

The crown serves as the primary point of interaction between an owner and their watch. From specially designed tools for gloved hands to the significance of "International Orange" in aerospace applications, we dive into the evolving landscape of human-machine harmony in space exploration🚀

Big thanks to for selecting us as a semi finalist for the Louis Vuitton Watch Prize🚀 3D printing will have a significant impact on the future of manufacturing as precision and selection of materials continues to increase. Project One features the worlds first 3D printed steel movement bridge in a production watch. This is only the beginning of our journey and we can’t wait to embark on the next chapter with all of you, let’s go to space🚀

Super cool demo of some incredible 3d printing technologies in collaboration with our partners 🛰️

-fully 3d printed titanium Monolith Chassis using Direct Metal Laser Sintering

-Multi Jet Fusion printed wireframe cage

-full high resolution 3D scan of the actual 15536 Moon Rock recovered from the apollo 15 mission. The scan not only mapped 3d textures but also the colors, and was then imported into a 3d modeling software. We then printed a color accurate high res model with a technology called multicolored Polyjet.

The future is here!🚀

Swipe to see some images of the site where the rock was originally extracted from. The original rock was collected by the astronauts David R. Scott and James B. Irwin on August 2, 1971 at station 9A, (the second stop of the third moonrover excursion) at the edge of the Hadley crack. The age of the rock is estimated at 3.3 billion years, it has a weight of 317 grams, and consists of 40% Plagioclase, 40% Pyroxene, 18% Olivine and 2% Ilmenite.

The crew behind the mission🚀

Beyond watches, we are dedicated to being a platform for innovation. We are collaborating with engineers, scientists, artists, and aerospace pioneers. Each product is an expression of curiosity and excitement for pushing the boundaries of what’s possible.

Here’s the Barrelhand crew with our good friends at materialise helping to codevelop the next generation of the 3d printed Monolith chassis🛸

New device in development🛰️ any ideas what this is for?

New Monolith casebacks are in🚀 testing out Diamond-like Carbon (DLC) vs clear hard anodizing.

DLC (black) is a harder more resistant coating generally, however once scratched it reveals the silver metal underneath and cannot easily be resurfaced/finished.

A clear type III hard anodize is also highly abrasion resistant, chemically stable, and heat resistant with the added benefit of not easily seeing scratches since it still looks like the raw metal.

Will be testing some prototypes with both finishes to see how they wear/scratch over time, what would you guys pick from a technical and visual standpoint?

Simplicity🛸 While complexity is often appreciated in traditional watchmaking, Monolith focuses on a simple construction to optimize for reliability and maintainability.

We opted for standardized ISO screws so that the watch can be easily serviced/repaired with the tools and resources already available on the ISS as opposed to watchmaking specific tools for screw down caseback systems.

The caseback itself is also simple in architecture and uses a bidirectional gasket seat so that it can handle back pressures in the vacuum of space 🛰️

T-08 of our launch sequence: the Monolith Caseback

Space exploration pushes the boundaries of human capability. In such an extreme environment, maintenance and repair work become especially challenging. The Monolith caseback is specifically engineered to address these obstacles, utilizing aerospace-grade materials, ISO certified components, and part numbering systems based on NASA standards, ensuring seamless integration and simplified maintenance.

RB Metalworks setting up the printed titanium chassis for post processing on the 5 axis CNC. The parts are printed with extra material so that critical tolerances can be machined and surfaces can be cleaned up for final finishes. The arches at the base of the print are used to bind to the build plate to create a stable/flat print surface. In addition to printed steel, titanium, and aluminum, we will also be testing out a new aerospace alloy🛸 more info soon!🚀

T-09 of our launch sequence: the Monolith Window.

When venturing beyond the protective atmosphere and gravitational pull of our home planet, we find ourselves in an environment vastly different from that of Earth. Building products for space therefore requires us to optimize for conditions that are not typically considered in the development of Earth-bound products.

The Monolith Window strikes a balance between optical resilience and shatter resistance. In microgravity environments, a shattered crystal with fragments floating around your spacecraft would not only be unfortunate - it could become a serious hazard to your eyes and lungs.

During the ongoing development of Monolith, we have been exploring everything from the traditional hesalite and sapphire to more exotic materials like diamond slabs and bulletproof glass to identify the most suitable solution. Learn more about the Monolith Window with our latest article:
