The evolution of the automatic watch movement is a fascinating chapter in watch history that often goes unnoticed. It's a story of innovation, perseverance, and the relentless pursuit of perfection. This narrative centers around a British watchmaker, John Harwood, and a Swiss manufacturer, Fortis, who, in 1926, revolutionized mechanical watchmaking with the introduction of the automatic wristwatch. This invention not only changed the industry but also transformed the way we perceive and interact with mechanical watches today.
The early 1920s were a pivotal time for wristwatches. While the wristwatch had gained popularity during the Great War, it was still a relatively new and fragile invention. Reliability was a significant challenge, as every watch required daily manual winding to stay functional. This mundane task, as mundane as it sounds, was a genuine problem. The crown, a necessary component, was also a liability, as it exposed the movement to dust and moisture, leading to wear and tear over time.
Walter Vogt, the founder of Fortis, recognized this issue and sought to address it. He envisioned robust mechanical watches designed for everyday use, free from the vulnerabilities of the crown. This is where John Harwood came in. Harwood, a British watchmaker, had been contemplating a different solution to the winding problem. He questioned why the watch needed a crown at all and began experimenting with a self-winding system.
After years of experimentation, Harwood developed a novel concept in 1924. He secured a Swiss patent (No. 106583) for a self-winding system built around an oscillating weight. This weight, attached to the wearer's wrist movement, 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 allowed the watch to generate energy from the wearer's motion, eliminating the need for manual winding.
However, turning this patent into a practical product required a different kind of expertise and industrial execution. Harwood needed a manufacturing partner, and that's where Fortis came in. Fortis, with its manufacturing infrastructure, engineering capabilities, and institutional conviction, committed to bringing the automatic wristwatch from concept to serial production. This partnership proved to be a turning point in watchmaking history.
The challenge was immense. The entire construction of the watch had to be rethought to ensure the oscillating system could withstand the stresses of everyday use. The caliber had to be protected, and reliability had to be engineered into every component. Fortis and Harwood worked tirelessly to overcome these technical hurdles, ensuring the watch would function reliably without constant servicing.
On July 13, 1926, the first Fortis Harwood automatic wristwatches rolled off the assembly line in Grenchen, Switzerland. These watches were groundbreaking, featuring no crown and a design that set them apart from their contemporaries. The wearer would set the time via the rotating bezel, and the movement would power itself through the wearer's motion. This radical departure from traditional watch design sparked curiosity and excitement in the industry.
The Fortis Harwood automatic watches underwent various iterations, each refining the design and functionality. Around 30,000 of these watches were produced, a significant number by the standards of the time. The automatic winding system evolved rapidly, with full rotors replacing the bumper system, offering greater efficiency and longer power reserves. Movements became thinner, more precise, and more refined, further enhancing the watch's performance.
The impact of the automatic wristwatch on the industry cannot be overstated. It set a new standard for mechanical watches, making them more practical and user-friendly. The daily ritual of winding became a choice rather than a necessity, and the relationship between the wearer and the watch's mechanical heart became more intimate and rewarding. This evolution in watchmaking has continued to shape the industry, with every automatic movement today tracing its roots back to that pivotal moment in 1926.
Interestingly, the origins of the automatic wristwatch were almost forgotten. Rolex's dominance in the post-war decades led to a blur in the popular imagination, with some believing the automatic wristwatch had begun in Geneva. However, Rolex publicly acknowledged John Harwood's invention in 1956, correcting their earlier advertising and paying homage to the British watchmaker. This act of industry acknowledgment is a testament to the importance of recognizing and celebrating innovation.
Fortis, the company founded by Walter Vogt, continues to build upon this legacy. They still manufacture watches in the same building in Grenchen where this chapter of watchmaking history began. The company's philosophy remains true to Vogt's vision of robust mechanical watches designed for real-world performance. The centenary of the automatic wristwatch serves as a reminder of the groundbreaking innovation that transformed the industry and continues to shape it today.
In conclusion, the automatic watch movement is a testament to human ingenuity and the relentless pursuit of perfection. It has not only changed the way we make watches but also how we interact with them. The story of John Harwood and Fortis is a reminder that sometimes, the most significant innovations are those that make the invisible visible, transforming the ordinary into something extraordinary.
