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 MDM Family found a new home and celebrated it BIG 🍾✨
The doors are officially open at the new address — Rämistrasse 5, 8001 Zurich — and we celebrated in style. Great people, great vibes, bold watches, and plenty of reasons to raise a glass.
Right in the heart of Zurich, the new space feels exactly like us: special, colorful, historic, and full of character.
Here’s to new beginnings, good times, and ticking into the future together.

We are incredibly excited about this big step and can’t wait to welcome you into our new home at Rämistrasse 5.
We found the perfect place. Beautifully enough, it sits just opposite our father’s favourite restaurant @kronenhalle (We like to think of it as his sign from heaven)
Please note that we will be closed from February 9 to 15 while we move.
From Monday, February 16, we look forward to opening our doors at our new address:
Rämistrasse 5, 8001 Zürich. #moving #mauricedemauriac #rämistrasse
BE READY FOR OUR NEXT BIG MOVE✨. New address, same spirit. See you soon at Rämistrasse 5, 8001 Zurich. #rämistrasse #mauricedemauriac #bigmove
Incredible! The Russell Story continues…
After visiting us during the @zurichfilmfestival Russell invited us to personally deliver his Rallymaster IV to his farm in Nana Glen. So after launching it in Melbourne during AO 2026 we went to see him on his farm and stayed full three days. We had just an amazing TIME.
This is a real dream coming true and an once in a life time experience! But most important it shows that also Hollywoodstars are only human beings who love community & family ❤️
