The evolution of the automatic watch movement is a fascinating chapter in watch history, often overlooked outside of specialist circles. It's a story of innovation, perseverance, and the relentless pursuit of perfection. At its core, the automatic movement represents a fundamental shift in how we experience watchmaking, transforming a daily chore into a seamless, almost invisible process. This is the story of John Harwood and Fortis, two visionary watchmakers who, in 1926, changed the course of mechanical watchmaking forever.
The Problem: Daily Winding, Daily Hassle
In the early 1920s, the wristwatch was still a relatively new phenomenon. While it had gained popularity during the Great War, it was far from perfect. Reliability was a major concern, and daily manual winding was a necessary chore for every watch owner. This process, though mundane, was a constant source of frustration. Every time the crown was pulled out or turned, the movement was exposed to dust and moisture, leading to wear and tear over time. The crown, an essential component, had become a liability, undermining the very purpose of the wristwatch as a practical, everyday timepiece.
The Solution: The Automatic Watch
John Harwood, a British watchmaker, saw a solution to this problem. He asked a simple yet revolutionary question: What if the watch didn't need a crown for winding? After years of experimentation, Harwood developed a self-winding system that harnessed the natural movement of the wearer's wrist. This system, patented in 1924, featured an oscillating weight that transferred energy to the mainspring through a bumper system. Unlike the 360-degree rotors that would later become standard, Harwood's weight operated within a limited arc, striking spring buffers at each end of its travel. This innovative design was the birth of the automatic watch, a movement that would change the industry forever.
The Partnership: Fortis and Harwood
Turning a patent into a real-world product required more than just an idea. It needed industrial execution at scale. Fortis, a Swiss manufacturer founded by Walter Vogt in 1912, recognized the potential of Harwood's invention. The two men formed a partnership that would define watchmaking for the next century. Fortis committed to bringing the automatic wristwatch from patent concept to serial production, a technical challenge that proved more demanding than it may sound today.
Technical Challenges: Engineering Reliability
Creating an automatic mechanical wristwatch was no easy feat. The watch's entire construction had to be rethought from the ground up. The oscillating system had to survive constant motion on the wrist, and the movement had to remain protected despite the elimination of the traditional winding process. Reliability had to be engineered into every single component, as the promise of the automatic watch could not be fulfilled by a mechanism that required constant servicing. Fortis had the manufacturing infrastructure, the engineering capability, and the institutional conviction to overcome these challenges.
The First Automatic Watch: A Revolutionary Design
On July 13th, 1926, the first Fortis Harwood automatic wristwatches began leaving the manufacture in Grenchen, Switzerland. These watches were startling objects by the standards of the era. Most strikingly, they had no crown at all. The wearer would set the time via the rotating bezel, and the movement would power itself through the wearer's motion. The component that every other watch in existence considered essential had simply been removed. This was a bold, innovative design that would set the standard for automatic watches to come.
The Evolution of the Automatic Watch
The automatic winding system would evolve rapidly. Full rotors, capable of winding in both directions through a full 360-degree arc, replaced the bumper system as the standard, bringing greater efficiency and longer power reserves. Movements became thinner, more refined, and more precise. The industry moved forward, but the central principle remained unchanged: a mechanical watch could draw energy from the motion of its wearer. This principle remains unchanged today, with every automatic movement in every watch you own tracing its lineage back to that Grenchen manufacture in July 1926.
The Legacy: A Movement That Changed the Industry
The impact of the automatic watch on the industry cannot be overstated. It transformed the relationship between the wearer and their timepiece, making it more practical and less of a chore. The daily ritual of winding became a choice, not a necessity. This movement, born from the partnership of Fortis and Harwood, has become the defining mechanical movement type of the modern era. Every rotor that spins inside every automatic watch today carries that date in its DNA, a testament to the enduring legacy of this revolutionary invention.
Conclusion: A Movement That Lives On
In conclusion, the evolution of the automatic watch movement is a story of innovation, perseverance, and the relentless pursuit of perfection. It is a movement that has changed the industry forever, and its impact can be felt in every automatic watch that is worn today. As we celebrate the centenary of this revolutionary invention, we must pause and reflect on the vision of John Harwood and the commitment of Fortis. Their partnership has left an indelible mark on watchmaking, and the automatic movement remains a testament to their ingenuity and foresight. It is a movement that lives on, a movement that breathes, a movement that requires attention, and a movement that rewards a tactile interaction with the mechanical heart that is a movement.
