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 team’s Lada Niva is the perfect symbol of the @dakarrally spirit. Not a polished promise of high technology, but an honest character. Angular, robust, reliable. A vehicle that doesn’t ask whether the road is comfortable, but whether it is possible. In the same way, the Lada moves through landscapes larger than any ego and through days longer than any comfort zone.
We are proud to be part of this years Dakar with the @oasis_rally_team 🏜️🏁
#MauriceDeMauriac #MDM #dakarrally #oasisrallyteam
This watch rises from the sands of the Dakar. 🏜️🏁
Built on the Chrono Modern — the Oasis Rally Team watch carries our DNA within it: clear, honest, uncompromising. Its sand-coloured dial with fine texture feels as though the desert wind itself has shaped it. It captures the light of the Dakar and carries it forward — through the stages and into the everyday life of true rally enthusiasts. The tachymeter in the colours of blue flames evokes heat, energy, and passion.
The serrated bezel stands for resilience, reducing glare under extreme conditions; the heat-resistant textile strap is made for dust, heat, and constant movement. Sapphire crystal with double-sided anti-reflective coating, 100 metres of water resistance, and a robust stainless-steel case make this watch a companion that doesn’t ask questions — it simply goes with you.
Inside beats the ETA 7750. Visible through the sapphire case back, defying every movement. Here, mechanics become emotion. Time gains body and soul.
This watch is not a souvenir of the Dakar.
It is part of it.
