Philippe Stern, Honorary President of Patek Philippe, Passed Away on 14 June 2026

A man who has been crucial in shaping the brand as we know it, Philippe Stern, General Director as of 1977, then President of Patek Philippe from 1993 to 2009, and father of the current President, Thierry Stern, passed away on 14 June 2026, in his 88th year. Considered one of the most influential business leaders of his time and in the industry, Philippe Stern will leave an indelible mark on Patek Philippe, known for preserving its independence and establishing its stature as one of Switzerland’s leading watchmaking companies. While it does not indicate the reason for his death, the brand notes that “he led a life marked by passion and excellence”.

Born in 1938 in Geneva, Philippe Stern grew up surrounded by watchmaking. His grandfather, Charles Stern, as well as the latter’s brother, both dial makers (with the Cadrans Stern Frères company), had acquired the Patek Philippe manufacture in 1932, and his father, Henri Stern, had just joined the company. Following the family tradition, Philippe Stern began climbing the ranks within the company. After graduating with a degree in economics and commerce, he worked in New York for the Henri Stern Watch Agency from 1963 to 1966. Upon returning to Geneva, he continued working for the family business in various departments.

During the 1970s, alongside his father, then President of Patek Philippe, Philippe Stern “played an increasingly important role in managing the company. His numerous trips abroad helped to expand Patek Philippe’s visibility in both existing and emerging markets”. This, combined with his younger, fresher vision of the watch industry, played a role in the launch of one of the brand’s most influential watches, the Nautilus, in 1976. It was Patek’s answer to the growing market for steel luxury sports watches, appealing to a new class of clients.

In 1977, Philippe Stern was appointed General Director of Patek Philippe, right in the middle of the quartz crisis. While many believed it was the end of the mechanical watch, Philippe Stern disagreed and continued manufacturing traditional watches and investing in the development of the tools to produce them. And while many historical Swiss watch companies were forming groups to survive, Mr Stern believed in preserving the independence of the family venture.

Beyond the introduction of the Nautilus collection, Philippe Stern was responsible for several other achievements, such as the creation of the Calibre 89, back then the world’s most complicated portable mechanical watch. The result of nine years of R&D, it featured 33 complications and was launched to mark the brand’s 150th anniversary, among other impressive limited-edition wristwatches, including chiming watches. Philippe Stern also made a point in commissioning and developing Rare Handcrafts timepieces from artisans, even when these pieces were less successful, thus preserving these precious skills.

“In 1993, Philippe Stern became President of Patek Philippe, representing the third generation of the Stern family in this role. His primary concern remained preserving the financial and technical independence of the family manufacture,” explains Patek Philippe’s official communication. Another important moment in his career was the vertical integration of the production, by consolidating all of Patek Philippe’s Geneva workshops into a new, state-of-the-art manufacture in Plan-les-Ouates, where the brand is still headquartered. In 2001, another important step was the opening of the Patek Philippe Museum in Geneva, one of the world’s most remarkable watch collections, bringing together models from his own brand as well as exceptional timepieces illustrating the entire history of watchmaking since the beginning of the 16th century.

On the other side of the spectrum, Mr Stern was also responsible for the creation of the Patek Philippe Advanced Research Concept in 2005, which gave rise to highly technical models and brought silicon into current production. In 2009, together with his son Thierry, he formalised all the requirements related to Patek Philippe watches by providing the manufacture with its own seal of quality, the Patek Philippe Seal. That same year, Philippe Stern passed the presidency to his son Thierry Stern, and he later served as Honorary President of Patek Philippe.

Philippe Stern passed away at age 88 on 14 June 2026. He was also a father, a husband, an accomplished skier, a great sailor and a lover of Lake Geneva. Farewell, Mr Stern…
