Beyond the Moonwatch: Barrelhand's Monolith Aims to Redefine Timekeeping for Modern Space Exploration

When you think of space exploration and watches, one name immediately comes to mind: Omega. For over half a century, the Omega Speedmaster chronograph has held an almost mythical status, inextricably linked with humanity's ventures beyond Earth's atmosphere. Its selection by NASA for the Apollo missions solidified its place in history, a legacy famously cemented by its crucial role in timing a 13-second engine burn that helped save the crew of Apollo 13. This single event transformed a robust tool watch into the legendary "Moonwatch," a moniker Omega has leveraged extensively through official partnerships and countless commemorative editions. While other timepieces have certainly ventured into orbit and beyond, the Speedmaster remains the undisputed icon of space horology.

However, the landscape of space exploration is changing rapidly. The advent of private spaceflight companies and NASA's renewed focus on manned missions to the Moon and potentially Mars signal a new era. This evolving frontier, with its unique demands and technological advancements, presents an opportunity for innovation in the tools astronauts rely on. It's into this new space age that a small Californian start-up, Barrelhand, is stepping, proposing a radical departure from the established order with a watch they claim is the first truly purpose-built for the rigors of modern space exploration: the Monolith.

Challenging the Status Quo: Why a New Space Watch?

The Omega Speedmaster, while historic and capable, was never originally designed with the specific, extreme conditions of space in mind. Its selection was the result of rigorous testing of available off-the-shelf watches, where it simply performed better than others. Karel Bachand, founder of Barrelhand, an engineer with prior experience designing clinostat machinery for NASA (devices used to simulate microgravity), understands the limitations of adapting terrestrial technology for extraterrestrial environments.

"Space is the harshest environment we've ever gone to," Bachand states. "When we first did it 50 years ago, there were no tools for it. NASA just tried to find off-the-shelf watches that were the best available. When the Speedmaster was selected it was never designed with space in mind, it just happened to pass the tests better than others. There was still plenty of room for improvement."

Bachand points to documented issues with the Speedmaster during its early space use. NASA engineers noted that its accuracy could be affected by extreme temperatures and acceleration. Other practical problems arose: lume flaking off the dial, or the Velcro strap becoming clogged with abrasive lunar dust during moonwalks. Despite these known areas for improvement, Bachand argues that there has been a surprising lack of fundamental innovation in space watches over the past five decades, especially considering their potential life-or-death importance as backup timing devices when complex electronic systems might fail.

Omega has introduced more modern space-qualified watches, such as the Speedmaster Skywalker X-33. This quartz-based model, qualified by the European Space Agency, represents a technological leap. However, it has its own limitations. The X-33 is primarily certified for Intra-Vehicular Activity (IVA) use, meaning inside the spacecraft or station. Its electronic liquid crystal display is vulnerable to the extreme cold of Extra-Vehicular Activity (EVA), or spacewalks, where temperatures can plummet dramatically in the shade. For EVA, a mechanical watch is still preferred for its ability to function independently of electronics and displays that might freeze or malfunction.

Furthermore, quartz watches, while accurate, are susceptible to the higher levels of radiation present in outer space, which can degrade electronic components over time. A mechanical watch, relying on springs, gears, and levers, is inherently more resistant to radiation effects. However, traditional mechanical watches face the immense challenge of operating reliably across the vast temperature swings experienced in space, from the scorching heat of direct sunlight to the cryogenic cold in shadow.

Engineering for Extremes: The Monolith's Innovative Approach

Barrelhand's Monolith is designed to tackle these challenges head-on, leveraging advanced manufacturing techniques and materials science. The watch, currently in its prototype phase, utilizes a modified Sellita SW300-1b mechanical movement. This movement was chosen not only for its inherent robustness but also for its serviceability – a critical factor for potential repairs in a remote environment like the International Space Station (ISS).

Barrelhand has significantly upgraded the base movement to enhance its performance in space. These modifications include improvements to magnetic resistance, crucial in environments with complex electrical systems, and enhanced shock resistance to withstand the vibrations and impacts associated with launches and maneuvering. The goal is to achieve a daily accuracy of +/- four seconds, a high standard for a mechanical watch operating under such demanding conditions.

Bachand, drawing on his engineering background and NASA-related work, identifies engineering for extreme temperature as the single most difficult hurdle for a space watch. This is where Barrelhand's expertise in 3D printing, also known as additive manufacturing, becomes revolutionary. The Monolith's case is not traditionally machined; instead, it is 3D printed from a high-performance material called "scalmalloy."

Scalmalloy is an alloy of scandium, aluminum, and magnesium, typically used in specialized, small-scale aerospace components where strength and weight are paramount. Bachand explains the material's advantage: "We get the same strength specs as titanium for half the weight, which is insane." This results in an incredibly lightweight watch, weighing around one ounce (approximately 32 to 33 grams). While not designed purely for ultralight status, this weight reduction is significant in space exploration, where launch costs are astronomical – sending one kilogram to the moon currently costs around $1.4 million. Shaving even a few grams off essential equipment can translate into substantial savings.

The use of 3D printing allows for complex geometries impossible with traditional manufacturing. Barrelhand has exploited this by designing the Monolith's case with an internal air pocket within its walls. This innovative structural element creates an insulating layer, enabling the watch to function reliably across an astonishing temperature range: from a frigid -120°C (-184°F) to a scorching +120°C (248°F). This range far exceeds the capabilities of standard watch construction and is critical for surviving the rapid temperature shifts encountered during EVA, moving between direct sunlight and deep shadow.

Beyond Temperature: Addressing the Unique Challenges of Space

Barrelhand's focus extends beyond just temperature resistance. They have considered numerous other factors unique to the space environment:

• Shatter-Proof Crystal: In microgravity, floating debris poses a significant hazard. The Monolith features a specially designed shatter-proof crystal that is intended to dent upon impact rather than fragmenting, preventing dangerous "floating shrapnel" inside a spacecraft or habitat.
• On-Orbit Serviceability: Sending specialized tools and personnel to space for watch repair is impractical. Barrelhand has redesigned the movement screws and case construction to make the watch serviceable using standard tools already available on the ISS, empowering astronauts to perform basic maintenance or repairs if necessary.
• Aerospace-Grade Seals: Traditional rubber gaskets used for waterproofing watches degrade and become brittle at the extreme low temperatures of space. Barrelhand researched the sealing technology used in ISS airlocks and partnered with a supplier to create an O-ring seal made from aerospace-grade fluorosilicone. This material maintains its flexibility and sealing properties even when frozen, ensuring the case remains sealed against the vacuum of space.
• Outgassing Prevention: Materials can emit absorbed gases into the surrounding atmosphere, a phenomenon known as outgassing. On Earth, this might just cause a temporary smell (like VOCs from new plastic products), but in the closed environment of a spacecraft, outgassing can contaminate the air and sensitive equipment. Barrelhand has meticulously selected materials for the Monolith that do not emit volatile organic compounds (VOCs), ensuring the watch is safe for use in confined space habitats.

By addressing these often-overlooked details, Barrelhand aims to create a watch that is not just functional in space, but truly optimized for it. This rigorous approach to engineering for the most demanding environment known to humans has a beneficial side effect: it results in an incredibly robust and capable tool watch for use on Earth as well. For instance, the Monolith is pressure-tested to depths of 580 meters, far exceeding the requirements for most terrestrial activities.

3D Printing: The Future of Watchmaking?

Karel Bachand is a strong advocate for the potential of additive manufacturing in precision industries like watchmaking. Barrelhand's first watch, the Project One, released in 2020, served as a crucial research platform to test the capabilities of metal 3D printing for intricate watch components. The Project One was even recognized as a semifinalist for the prestigious LVMH Watch Prize, highlighting the potential of their manufacturing approach.

"For watches, it's kind of the holy grail of engineering: It's super small and super precise," says Bachand about metal 3D printing. Demonstrating the ability to 3D print complex components like a movement bridge, a critical structural element in a mechanical movement, is a powerful validation of the technology's maturity and precision. Bachand notes that showing this capability to traditional watchmakers often elicits excitement and recognition of the potential.

While 3D printing is increasingly common for prototyping and even some production in various industries, its application in high-precision mechanical watchmaking, particularly for critical structural components and cases designed for extreme environments, is still relatively novel. Barrelhand is at the forefront of demonstrating how this technology can enable designs and material uses that were previously impractical or impossible with traditional subtractive manufacturing methods (like machining).

The ability to create complex internal structures, such as the insulating air pocket, or to work with advanced alloys like scalmalloy that are difficult to machine, showcases the transformative potential of additive manufacturing in creating next-generation performance tools like the Monolith. It represents a significant shift in how watches, especially those intended for demanding applications, can be designed and built.

The Path to Space: Certification and Adoption

Getting a new piece of equipment certified for use by space agencies like NASA is a notoriously lengthy and bureaucratic process. Omega's half-century relationship and established flight heritage present a significant challenge for any newcomer. While Barrelhand intends to pursue the official certification route, they are also adopting a more direct, "grass roots" approach.

This involves engaging directly with individual astronauts, scientists, and engineers within the space community. Bachand believes that these individuals, who intimately understand the demands and limitations of current equipment, will be the most receptive to the Monolith's innovative design and capabilities. Many astronauts are not only watch enthusiasts but are also deeply interested in cutting-edge tools and technological advancements that can improve safety and efficiency in space.

"Everyone that we've spoken to really understands the mission and sees the need for it, the need for innovation and to continue improving on any tool," Bachand observes. He suggests that while history and status are factors for some, many in the space community prioritize performance and functionality above all else. "They don't always care about history or the status quo; they just want whatever's the best."

The strategy is that by getting the Monolith into the hands of those who would actually use it, and allowing them to experience its specifications and the meticulous thought behind its design, its merits will become self-evident. "When people get it in their hands and understand the specs, and the thought behind it all, I think it's going to be a no-brainer," Bachand concludes.

The rise of commercial spaceflight also opens new avenues for adoption. Private companies like SpaceX, Blue Origin, and others are developing their own protocols and equipment standards, potentially offering a less rigid path for new technologies to prove their worth compared to traditional government agencies. A watch purpose-built for space could find a market among these new space pioneers, as well as researchers, engineers, and even space tourists who desire a timepiece engineered to the highest possible standards for the extraterrestrial environment.

The Future of Space Timekeeping

The Barrelhand Monolith represents a bold vision for the future of timekeeping in space. It moves beyond adapting existing designs and instead focuses on building a watch from the ground up, specifically engineered to thrive in the vacuum, radiation, and extreme temperatures of outer space and planetary surfaces. By embracing advanced manufacturing techniques like 3D printing and utilizing cutting-edge aerospace materials, Barrelhand is pushing the boundaries of what a mechanical watch can endure.

While the Omega Speedmaster will forever hold its place in the annals of space history, the Monolith signals a new generation of space tools. Its focus on resilience, repairability, and performance in the most challenging conditions reflects the evolving needs of modern space exploration, from extended stays on the ISS to future missions to the Moon and Mars. Whether it ultimately replaces the Speedmaster as the official watch of space agencies remains to be seen, but Barrelhand's innovative approach has certainly set a new benchmark for what a space watch can and should be.

The development of the Monolith highlights a broader trend in the space industry: the increasing integration of advanced manufacturing and materials science to create lighter, stronger, and more capable equipment. It underscores the fact that even seemingly simple tools like a wristwatch require sophisticated engineering when destined for environments where failure is not an option. As humanity ventures further into the cosmos, the tools that accompany us must evolve, and the Barrelhand Monolith is a compelling example of that necessary evolution.

The narrative of space exploration is one of continuous innovation and overcoming seemingly insurmountable challenges. From the early days of Mercury and Apollo to the current era of the ISS and the dawning age of lunar and Martian colonization, each step forward requires new technologies and new ways of thinking. The Monolith, with its 3D-printed scalmalloy case, temperature-resistant design, and focus on practical space use, embodies this spirit of innovation. It's not just a watch; it's a statement about the future of engineering for the final frontier.

Barrelhand's journey to get the Monolith into space will likely be long and challenging, navigating both technical hurdles and institutional inertia. However, the fundamental principles behind the watch – designing specifically for the environment, leveraging cutting-edge technology, and prioritizing functionality and reliability – are sound. As private spaceflight expands and the need for robust, dependable equipment grows, the Monolith stands ready as a compelling alternative to the legacy systems, offering a glimpse into the future of space-qualified gear.

Ultimately, the success of the Monolith will be measured not just by its technical specifications, but by its adoption by those who live and work in space. If Barrelhand can convince astronauts and space engineers that their watch is the most reliable and capable tool for keeping time when everything else might fail, then the Monolith could indeed carve out its own significant chapter in the history of space exploration, stepping out of the shadow of the iconic Moonwatch and into the light of a new space age.
