Ferdinand Alexander ‘Butzi’ Porsche never set out to design a watch that would impact the world of horology. In fact, he never really set out to design watches. What he wanted was to create objects with a clear purpose and practical form. That pursuit, which gave the world the 911 and 904 Carrera GTS, also produced one of the most distinctive wristwatches of the twentieth century: the Porsche Design Chronograph I.
Today, that timepiece is regarded as a design landmark, or even an icon to some. But those labels risk flattening what is, at heart, a very Porsche story—one rooted in automotive design logic, personal conviction, and a refusal to embellish for embellishment’s sake. To understand the Chronograph I, you must first understand Butzi Porsche.
Born in Stuttgart in December 1935, Butzi Porsche grew up inside the gravitational field of the family name. His grandfather, Dr. Ferdinand Porsche, was one of the great engineering minds of the twentieth century. His father, Ferry Porsche, transformed that engineering legacy into a company defined by performance and restraint. Butzi absorbed those values early, though he expressed them visually rather than mechanically. Where earlier generations solved problems with pistons and crankshafts, he solved them with lines, proportions, and surfaces.
After studying design, Butzi joined Porsche in the late 1950s and became a creative influence. By the early 1960s, he was leading the design of what would become the 911. Unveiled in 1963, that
car adhered to Porsche’s essential design philosophy. It had relatively little decoration and curves shaped to accommodate the underlying mechanics. A year later, the gorgeous 904 Carrera GTS, penned by Butzi Porsche, debuted. The priority for both the 911 and 904 wasn’t to impress at a glance but to function optimally. That difference mattered to Butzi, who believed that the very best designs rarely announced themselves.
“Design must be functional and functionality must be translated into visual aesthetics, without any reliance on gimmicks that have to be explained,” he once said. It is a philosophy that explains in part why the 911 has aged so gracefully—and what the next chapter in his career would yield.
In 1972, Butzi Porsche stepped away from Porsche due to a shift away from family members in management positions. He then created his own company, Porsche Design, where aesthetic principles could be applied without compromise, free from committee decisions or trends.
The first product to emerge from that studio was not a pen, a pair of sunglasses, or a piece of luggage. It was a wristwatch. That’s because he believed a watch was the ideal medium for translating automotive-inspired design into an everyday object.
At the time, tool watches existed, of course—chronographs for pilots and racers, diving watches for underwater explorers and workers—but they were often visually busy. Polished cases, overwrought dials, applied logos, and decorative finishes were reasonably common. Black cases, when they appeared at all, were rare and usually accidental, the result of aging or military necessity.
Butzi Porsche looked at watches the same way he looked at dashboards. He cared about legibility above all else. In a Porsche cockpit, glare is the enemy. Shiny surfaces distract the driver and obscure information. The solution is matte finishes, high contrast, and visual hierarchy. Translating that logic to the wrist led to an obvious conclusion: the watch he was designing should be black.

When the Porsche Design Chronograph I was introduced in 1972 and entered broader production shortly thereafter, it was unlike practically anything else on the market. The case was finished in matte black via a vacuum coating process known as physical vapor deposition (PVD). The dial was black. The subdials were black. White hands and markers stood out sharply against the dial. A single red chronograph seconds hand—borrowed in spirit from Porsche instrument needles—served as the only accent. There was no polish, no excess. Every choice was made in service of legibility.
The Chronograph I treated black not as a stylistic gesture but as a practical one. The PVD coating cut glare, and the dial was arranged for instant comprehension. The watch was not designed to look fast. It was designed to be clear at speed.
That clarity also explains where the Chronograph I found its earliest and most visible audience. Mario Andretti was seen wearing a Porsche Design Chronograph I during his championship-winning 1978 Formula One season. A few years later, the watch appeared on Tom Cruise’s wrist in Top Gun, where its matte-black case and instrument-like layout blended with the film’s aviation hardware. In both cases, the Chronograph I was chosen not as a fashion statement, but because it looked—and functioned—like equipment.
Production was handled in Switzerland, with early examples manufactured by Orfina and powered by the Valjoux 7750 automatic chronograph movement. Porsche Design was not attempting to reinvent watchmaking mechanics. The innovation was conceptual and visual. Just as Porsche did not build engines for novelty’s sake, Butzi had no interest in reinventing movements. Reliability mattered. The message was delivered through form.
That language would prove influential beyond Porsche Design. Within a decade, black watch cases became in demand across the industry. Legibility became a selling point rather than an afterthought. Entire brands would later be built around the idea that watches should look like instruments. The Chronograph I did not merely anticipate that shift. It helped trigger it.
The present-day Porsche Design Chronograph 1 (modern examples use “1” instead of “I”)—such as the All Black Edition shown here—retains the look of the original while upgrading to a chronometer-rated movement and a lightweight titanium case with a black carbide coating.
Porsche Design continued to evolve the concept through the 1970s and 1980s. In 1975, a stainless-steel-finish version of the Chronograph I was introduced, offering the same design without the black coating. That same year, Porsche Design began specifying the Lemania 5100 automatic chronograph movement after the Valjoux 7750 became temporarily unavailable in the mid-1970s.
In 1978, Porsche Design entered into a partnership with International Watch Company (IWC), bringing its timepieces under the stewardship of one of Switzerland’s most established manufacturers. After that collaboration ended, production shifted to Eterna—owned by Porsche from 1995 to 2011—which manufactured Porsche Design watches from 1996 through 2013. Since 2014, Porsche Design’s watch assembly has been carried out by Porsche Design Timepieces AG in Switzerland.
Porsche Design went on to create a wide range of products, including bicycles, sunglasses, ballpoint pens, luggage, apparel, furniture, and kitchen knives. It even ventured into electronics, designing laptops, tablets, and smartphones. The company remained independent under the ownership of Butzi Porsche until the early 2000s, when he entered into a partnership with the Porsche carmaker. In 2017, Porsche Design became a wholly-owned subsidiary of Porsche AG.
When Butzi Porsche passed away in 2012, his design legacy was already secure. His sports car design work alone would have guaranteed that. But the Chronograph I had taken on a life of its own. Vintage examples became increasingly sought after, not because they were rare, but because they represented a turning point. Collectors began to see them not merely as Porsche merchandise, but as historically significant watches.
Porsche Design recognized that significance when it marked the 50th anniversary of the Chronograph I in 2022. The modern reissues were not nostalgic exercises. They were careful updates—faithful to the original proportions and aesthetics, but executed with modernized materials, coatings, and movements. The current versions are powered by Porsche Design caliber WERK 01.140 movements, which are essentially modernized, chronometer-certified versions of the Valjoux 7750.
Today, Porsche Design continues to sell the Chronograph I, including the All Black Numbered Edition, the 1975 Limited Edition, and the Utility Limited Edition.
Butzi Porsche didn’t care about making a watch that people would worship, collect, or turn into some legend. Like every project he touched, his focus stayed narrow and intense: solving a practical puzzle with logic, grit, and zero fluff. The Chronograph I works today not because it hit a trend, but because it never bothered to look for one. It was built as a piece of gear, and that refusal to decorate is exactly why it hasn’t aged. While most watches now get buried under layers of nostalgia and shiny bits, the Chronograph I holds its ground—a useful tool, made to be worn.
