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.
Made with love in Zurich
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.
To all the families 🌈❤️: We are all so wonderfully different. But two things unite us. The love of watches and family. As we usually talk so much about watches, today we would like to focus on family - on International Family Day.
You can’t choose your family. You have one. So it’s not always easy. But who says family has to be easy? Nobody. As a family business, we know all the facets of family joy, but also the moments when you have to fight for your family.
We wish everyone maximum enjoyment from the family on this day and always enough strength to stand up for the family.
We also call the Maurice de Mauriac community our family. You are also part of our family. We are not united by blood, but by our love of time, which we give a very special meaning to with watches.
If you ever have times that challenge you and your family is far away, look at your Maurice de Mauriac and you know you have a family at your side - your Dreifuss watch family.
All the best to you, your loved ones and your family for the time ahead.

Monday Motivation? Buy a new car! Welcome to the MDM Family INEOS GRENADIER Fieldmaster #035! 🌍
We were looking for a long time for a replacement for our old Landy, which unfortunately was no longer fit enough for the wild everyday life of watch lovers in Zurich...:-) He had this & that… and at some point we didn’t want to torture him anymore.
If you love the old Landrovers, you will eventually come to the INEOS Grenadier. The worthy successor to the original Landrovers. At first we were a bit strange. But once you have sat in this car, you are spoiled for other cars.
With him we can drive everything to our events and even the smallest watch boutiques he moves through the city and Switzerland as if they were nothing. And now we come to the quality and the mechanics – typical for watch souls: terrific!
He will now be embellished a bit and then he will drive through Zurich, bringing watches, hollowing watches, Totoro will stick his nose out of the window and it is often like in the old days, when Daniel drove through the city, many waved, conversations arose, watch fascination that jumped like sparks from one to the other. See you...

We did it! We were part of the SÄCHSILÜÜTE 2025! ⛄️💥 We can say that we are very attached to Zurich. It is our home. Zurich is the heart of our brand. Zurich is both an inspiration and a challenge.
With the Sächsilüüte, however, we have come even closer to Zurich. Not only did we create the official Sächsilüüte watch together with the ZZZ. We were also invited by Urs Bucher to walk with the @zunft_zu_wiedikon . An incredibly intense experience. 🌈💐🌸
We look back on the Sächsilüüte with our arms full of flowers and our hearts full of emotion. Thank you to everyone who experienced this day with us.
Massimo, Leonard, Masha
and the whole Dreifuss family

Welcome “Züri Date” SÄCHSILÜÜTE⛄️💥
The only mechanical watch that speaks Züridüütsch, from the only watch manufacturer in Zurich. A mechanical watch could not be more Zurich. But the Züri-Date SÄCHSILÜÜTE is even more.
She not only speaks the language of Zurich,
but also remembers the most important day in Zurich. The Sächsilüüte. As this always takes place on Mondays, SÄCHSILÜÜTE is written where MÄNTIG is usually written. And at 6 pm on the dot, the Böögg appears on the dial. As befits a Zurich watch, all of this is made here in Zurich with an automatic movement in the traditional craftsmanship. Now available online and in our workshop.
