The Grand Cœur is alive
With this watch, you get life, not only time
The WatchBros have brought the Grand Cœur to life. In her beats a blood-red heart. The Grand Cœur lives from the genes of Maurice de Mauriac’s founder and the creative power of his sons’ youth.
The Grand Cœur has an exceptional Manufacture movement, has been designed with transparency, and a unique red Sapphire Case back.
Those who hold the watch in their hands feel the mastery, become in awe, and feel that the watch is not representing the time, but the young, pulsating life.
Only 48 Grand Cœur will be available. The number stands for the place where each Grand Cœur comes to life – Tödistraße 48 in Zurich. 48 beating hearts that beat for the wearers of the watch. A watch and life can hardly be more intense.

Watch Specifications
Grand Cœur 3038
In our see-through cases, a red, anti-reflective sapphire crystal reveals the vibrant caliber. You have the feeling of being able to see and feel the soul of the mechanical automatic movement. The watch is alive. This automatic movement with a central rotor is specially made to our quality standards by Concepto. It beats 28,800 times per hour, has an Incabloc shock protection system, 29 jewels, and 48 hours of power reserve. Grand Cœur – Impulsive Red
Massimo (28) and Leonard Dreifuss (25), have built the Grand Cœur, as both a homage to their father and as a beacon emblematic of the future vision the brand hopes to embark on. The watch aims to symbolize and honour life, and is therefore customised with its own personalised heartbeat for its wearer. This is expressed by moving the balance and the escapement to the top of the movement and the red of the case back. Grand Cœur Pushers

We spared no expense for the Grand Cœur box and used only the best material. The packaging consists of an inner and outer watch box. Both are covered with leather. The inside is made of Soprano leather. The inner watch box is designed for traveling. DLC coating
Titanium with a DLC-coating (Diamond-Like-Carbon) stands out via its beautiful grey / black colour. DLC makes stainless steel extremely abrasion and scratch resistant. Moreover, the layer of carbon applied in a state-of-the-art vacuum process is also highly anti-allergenic. Made with love in Zurich
The heart of Maurice de Mauriac beats near the Paradeplatz in the atelier located in the Tödistrasse. One encounters Maurice de Mauriac always and everywhere as a personable, human and warm family business.1

Skeleton
How much of the clock can you leave out in order to pay homage to the movement. Every Skeleton fan has his own tolerance limit. For us, however, Skeleton watches are not just omitted. We added the dimension of the open heart with the use of glass and color. You don't just see time passing, you see it living. These watches live with you.

The heart of Maurice de Mauriac beats near the Paradeplatz in the studio in Tödistrasse. Maurice de Mauriac always and everywhere meets you as a friendly, human, warm family business. All watches are dreamed, developed and built here with love.
When Russell invites you to the Venice Film Festival, you arrive in style. ✨
What an honor and privilege to be part of the chosen small crew witnessing the premiere of Russell’s heart project: WHAT LOVE BUILDS ❤️
His biography, documenting 47 years of making music and the incredible journey behind it, was brought to life on the big screen in the sold-out Sala Grande at the Venice Film Festival — and honestly, it was simply out of this world.
From Zurich, to Australia, and now to Venice… we couldn’t be more proud to have been a small part of Russell’s journey over the past year.
What a year it has been for us. ❤️
Thank you so much, Russell. We truly appreciate it all and never take any of these incredible moments for granted.
Here’s to music, friendship, unforgettable experiences, and a year we will never forget. 🥂✨

From the stands to the big screen. 💙🤍
Still trying to take this one in…
Seeing our video live in the stadium in front of 18,000+ people was a moment we’ll never forget.
Growing up in Zürich, going to FCZ games since we were kids, we never imagined that one day we’d see something we created being shown in the stadium in front of thousands of people.
From watching the games in the stands to seeing our work on the big screen — what a feeling. 🥹
130 years of FCZ. We couldn’t be more proud to be a small part of it.
A dream come true. 💙🤍⚽️

Now Time Belongs to the Champions 🥇🇨🇭🎾
One final rally. A brief moment of silence. Eyes fixed on the line. Then arms in the air. Teammates rushing onto the court. Embraces. Celebration. Players become Swiss Champions. One weekend becomes part of tennis history.
At the 2026 Interclub NLA Finals in Lucerne, TC Froburg Trimbach (Woman) and TC Seeblick (Men) earned the national title.
Point by point. Match by match.
But above all, together. Because Interclub is tennis in its purest form. You stand alone on the court, yet you never play only for yourself. Every point also belongs to those who cheer you on, encourage you, lift you up after setbacks and believe in the next rally.
Leonard Dreifuss had the honour of presenting the new Swiss Champions with a very special keepsake: the Rallymaster Swiss Tennis anniversary watch. A timepiece created for all those moments when the match could still go either way. For the games that seemed to last forever. And for that one final point that turns a player into a champion.
The entire Dreifuss family warmly congratulates the champions of Lucerne. You didn’t just win a title.
You created a moment in time that no one can ever take away. We make time. You made it unforgettable✨
