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.

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.

A super interesting and exceptional atelier; a family that lives and loves your craft and produces distinctive watches that have enormous character and exclusivity. Experience exclusivity!
I had a special wish and the Mauriacs made it possible. That is the quality of small but demanding companies.
Family business with heart and flair !
Creative, innovative, fresh and modern. For all those who love the special and unconventional. In addition, an extremely friendly reception, so that the visit to Tödistrasse 48 immediately became the highlight of the week. Our recommendation is: A MUST for everyone who loves the individual and unique ! Rating in Gault-Millau points: a smooth 20 !
Something of the most interesting in Zurich!
No industrial, sterile marketing of the usual pilot watch brands but personal advice with competence, heart, brain and humor.
The fascination for the watches noticeable and yet the contact with Leo and Massimo is as personal and direct as it can be.
Also, the selection of watch straps is infinitely large and there is something for every taste.
I bought a new watch strap for my IWC watch. Super selection and price. Very nice and courteous service. Thank you very much.
