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.
Indian Summer in Zurich 🍁💗
Sometimes all it takes is a sunny October Sunday to bring back a taste of summer. The family gets together, friends join in, jackets stay unbuttoned, and a short walk turns into an entire afternoon. One of those moments you’d love to hold onto forever.
We spent these last warm hours with our ZÜRI-DATE BRONZE PINK—a watch that tells a little more of your story with each passing day. With bronze that changes over time and a shade of pink that refuses to let summer go.

In pink and ready for a ride 💗🏍️
Our Züri-Date Pink, inspired by Zurich’s tram No. 10, now in full bronze and ready to hit the road.
And while we’re out riding, we ride for a reason. Every October, for every pink watch we sell, we donate to @krebsliga in support of Breast Cancer Awareness Month
Good rides with pink vibes for a good cause. 💗

ZFF Award Night 2026 — it’s a wrap. 🎬✨🪩
Dancing with family. Laughing with friends. Watching great movies. Meeting old friends and new faces.
And then — seeing the legend Andy Garcia, both in real life and on the big screen. ✨
A night full of films, laughter, music, good people and a little bit of magic.
What more could you wish for in one night?
Until next year, ZFF. 👀👋🏻

3…2…1… ACTION! - On the court 🎬🎾
We were proud to sponsor Tennis tournament of the Zurich Summit 2026 and celebrate the winners with 2x Swiss Tennis Rallymaster.
This year, the tournament was part of the vibrant atmosphere surrounding the Zurich Summit, a prestigious two-day boutique conference bringing together leading filmmakers, executives, agents, entrepreneurs and investors from film, entertainment and technology.
With a unique focus on connecting the European and US markets, the Zurich Summit creates opportunities for cross-border collaboration, inspiring conversations and new ideas.
From the tennis court to the world of film, creativity and technology — we love seeing different worlds come together in Zurich. I

Homo Faber — An Island of Light. ✨
An entire island celebrating the people who make things by hand.
One of the most beautiful exhibitions we have seen , because at its heart is an idea we deeply believe in: craftsmanship matters.
Every room is another universe. Different materials, different traditions, different hands, but always the same obsession with detail, precision and creating something that lasts.
It felt very close to what we believe:
Our watches are not made to simply tell time. They are objects shaped by people, attention and countless small details. From the first sketch to the final hand finishing, it is the human touch that makes a watch feel like more than an object.
Homo Faber celebrates the makers.
We celebrate them too.
Because in a world of mass production, there is something quietly powerful about making fewer things — and making them well.
If you are in Venice, go. If you’re not — perhaps this is a good reason to come. 🇮🇹

72 hours in Venice 🇮🇹
Couldn’t fit more food or drinks into these 3 days…
We were just talking about how lucky we are that we get to travel together as siblings, and all three of us couldn’t be more grateful for everything we get to experience together. Sharing it makes everything so much more fun and meaningful. Wouldn’t be the same otherwise. ❤️
If you need some Venice inspiration, hit us up haha - we got you!!
Walked 15k, ate and drank like kings & queens all day long!
See you soon again, Venice! 🤍 #mauricedemauriac #venice #homofaber #italy #watches
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. 🥂✨
