Tennis has been part of our family ever since Maurice de Mauriac was founded.
Not as a marketing idea. Not as a sponsorship strategy. But as something that has shaped who we are.
Our father, Daniel Dreifuss, loved this sport. He loved its elegance, its fairness and the unique silence that exists in the seconds before a serve. He knew that tennis is about much more than points and victories. Tennis is respect. Discipline. Passion. And above all: time shared together.
That love lives on in our family.
Over the decades, we have had the privilege of becoming part of this world. As the official timekeeper of the Swiss Open Gstaad. Together with Stan Wawrinka, long before the world celebrated him as a Grand Slam champion. With Michael Lammer during Switzerland's great Davis Cup years. With Stan Smith, whose friendship led to the creation of a watch together.
They were never just individual projects. They were encounters. Friendships. Shared memories. Perhaps that is why our partnership with Swiss Tennis feels so natural. It is not a new story. It has long been part of ours.
When Swiss Tennis began preparing for its 130th anniversary, we immediately knew that we did not simply want to accompany this milestone with a watch. We wanted to say thank you. Thank you to a sport that has accompanied our family for decades. Thank you to the people who keep it alive. Thank you to everyone who knows that a tennis match can be far more than just a game.
That is how the Rallymaster Swiss Tennis came to life.
It carries the spirit of the original Rallymaster, created together with the American designer Carlton DeWoody – a passionate collector of vintage watches and an avid tennis player. From the very beginning, it was dedicated to the traditions of this sport. Not to the trophies. But to the moments in between. The focused gaze before the first serve. The handshake at the net. The silent understanding between two people that fairness matters more than winning a point.
With the 130th anniversary of Swiss Tennis, this story continues.
In this edition, limited to just 130 pieces. Yet its meaning reaches far beyond the wrist.
With every watch sold, part of the proceeds goes directly to supporting the next generation of Swiss Tennis. Because every great career begins with people who give their time. Parents. Coaches. Friends. People who believe in someone long before success becomes visible.
That is what Maurice de Mauriac is about, too. For us, time is not a number on a dial. Time is what connects people. Perhaps that is the true reason this watch exists. Not only to celebrate 130 years of Swiss Tennis. But as a tribute to a sport and its values, which have been part of our family for generations.
