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.

Made with love in Zurich

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.

Why we are here in Porto? Because of the weather🌞
No just! Because we found an amazing retailer @watch.garage .The owner André who became more a friend than only a retailer. We try to do business with mindliked people and always combine it with pleasure. Because at the end of the day everybody just wants to have a good TIME! We definitely had it here in Porto.
