Maurice de Mauriac Celebrates 130 Years Of Swiss Tennis With A New Rallymaster
Switzerland has long been synonymous with both fine watchmaking and world-class tennis, making the partnership between Maurice de Mauriac and Swiss Tennis a natural fit. Unveiled during the Swiss Open Gstaad, the new Rallymaster Swiss Tennis pays homage to the national tennis federation’s 130-year history through a design inspired by the country’s colors and sporting heritage.

The latest release joins the growing Rallymaster family, a collection conceived in collaboration with Californian designer and watch collector Carlton DeWoody, whose vision blends vintage-inspired aesthetics with subtle references to the world of tennis.
Familiar Case, Sporty Proportions
The watch comes in a brushed stainless steel case measuring 39 mm in diameter, 12 mm thick, and offering 100 meters of water resistance, making it suitable for both everyday wear and active lifestyles. Turning the watch over reveals a sapphire exhibition caseback decorated with the Swiss Tennis anniversary logo, allowing a view of the automatic movement inside.

A Dial Filled With Tennis-Inspired Details
The highlight of the Rallymaster Swiss Tennis is undoubtedly its distinctive dial. It features an opaline silver finish with a vertically brushed central section that changes appearance depending on the light, shifting between bright white and silver tones.

Running across the center is the Rallymaster’s signature white tennis net motif, while a bold red central stripe reinforces the connection to the Swiss national colors. At 9 o’clock sits the collection’s characteristic small seconds display, framed in red and enhanced with yellow details that evoke the color of a tennis ball. Opposite it, at 3 o’clock, a red date wheel appears beneath a Cyclops magnifier, while matching red minute markers around the dial add further contrast. The applied round hour markers, together with the hour, minute and small seconds hands, are all filled with Super-LumiNova to ensure excellent legibility in low-light conditions.
One of the Rallymaster’s signature design elements remains the small seconds counter, which is graduated in 20-second intervals as a tribute to the time players were historically allowed between points during professional tennis matches.
Automatic Landeron Movement
Inside the watch beats the automatic Landeron 24 calibre, operating at a frequency of 4 Hz (28,800 vibrations per hour) and providing a 40-hour power reserve. The movement drives the hours, minutes, small seconds and date functions, delivering dependable everyday performance while remaining visible through the sapphire exhibition caseback.

Two Quick-Change Strap Options
Maurice de Mauriac supplies the Rallymaster Swiss Tennis with two interchangeable strap options, both equipped with quick-release spring bars for effortless changes. Buyers can choose between a sporty red elastic fabric strap that perfectly complements the dial accents or a brushed stainless steel Milanese bracelet, which gives the watch a more elegant and versatile appearance suitable for everyday or more formal occasions.

Limited To 130 Pieces
The Maurice de Mauriac Rallymaster Swiss Tennis is produced in a limited edition of just 130 individually numbered pieces, directly celebrating the 130th anniversary of Swiss Tennis. It comes with a price tag of CHF 2,500.
