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.
Russell Crowe receiving his „Life Time Award“ wearing our Rallymaster III 🏆👀 … and even mentioning us in his speech. What a honor, what a great actor and much more important what a great human being.✨
Thank you Russ for your trust and your kind words.
We will never forget.
Les Mauriacs ❤️

Welcome in the Family Russell Crowe ❤️✨
What a day & night to remember…Russ and his management paid us a visit during @zurichfilmfestival - but not just that, he bought a couple of watches: As a big tennis fan & player he bought the (nearly sold out) Rallymaster III #71 & since he got his „Lifetime Achievement Award“ he bought the Legacy. If that wasn’t enough he invited us for dinner, after he got his award, he presented one of his closest friend a Lazio collored watch, which happens to be the same colors as Zurich 🤍💙.
We are truly grateful for calling Russ now a family member - such a great & humble & funny person. This we will never forget…Thank you again @russellcrowe for this unique day.
PS: Never stop dreaming 💭🌙 (slide 5) , we invited Russ for a watch workshop in our atelier but he never replied. Yesterday he came out of nowhere to our shop. Sometimes the universe has a plan which you just don‘t know yet…

5 Star Service for 5 Star Concierge ⭐️⭐️⭐️⭐️⭐️
A few weeks ago, Leonard was in Turkey and took the opportunity to deliver another two watches to the Les Clefs D’Or community - the Union Internationale des Concierges d’Hotel.
Metin Can Yildiz and Mehmet Onur Yigit, concierges at the Peninsula Istanbul, an impressive 5-star hotel directly on the Bosphorus, now wear the watch we especially developed for and together with Les Clefs D’Or.
They were able to choose a watch strap on site and opted for Peninsula Green.
It’s just wonderful to get direct feedback, to experience joy and pride - to be close. It gives us a lot of energy!
Thank you again for the hospitality you showed us.
Massimo, Leonard, Masha and the whole Dreifuss family.

We are celebrating 100 years of RIOJA! 🍷🍇
Exactly 100 years ago, Rioja became the first Spanish wine region to receive the DO designation of origin. Today, Rioja is one of the world’s most important wine references. As with high-quality Swiss watches, the quality of Rioja wines is based on high craftsmanship, tradition, and precision. That is why we are participating in this anniversary event. There will be a variety of wines to taste, accompanied by tapas and music. During the evening, our L3 Spheric Red will be raffled off, its brick-red dial reminiscent of the color of a Rioja Gran Reserva.
PARK HYATT HOTEL, ZURICH
