rand Cœur. This is the name of the new watch from the Zurich brand Maurice de Mauriac. The watch is the birth certificate for a new era: The Grand Cœur is the first watch developed only by Massimo and Leonard Dreifuss, the sons of founder Daniel Dreifuss, who are now taking over the sceptre.

To mark this new era the brothers have worked tirelessly to bring out the Grand Cœur. From its conception, to its design and development, brothers 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 symbolise and honour life, and is therefore customised with its own personalised heartbeat for its wearer.

For their first creation, the Dreifuss brothers have opted for an exceptional Manufacture movement with a high degree of transparency in a typical Maurice de Mauriac case. The heart of the watch beats behind the red sapphire crystal of the “L3 sees red”, the last watch developed by their father, which is used as the red crystal back for the Grand Cœur and reveals the mechanical automatic movement.

The Grand Cœur pulses with the Concepto Manufacture REF 3038 calibre, an automatic movement with a central rotor. It beats 28,800 times per hour, has an Incabloc shock protection system, 29 jewels and 48 hours of power reserve. For the Grand Cœur, the balance wheel and escapement are moved to the top of the movement. The titanium case with a diameter of 45mm has a DLC coating, a domed sapphire crystal and screw-down pushers. The strap is made of rubber with red stitching.

The Grand Cœur is available online, in the Zurich shop and from 19 November to 24 December in the pop-up store at Bleicherweg 10 in the heart of Zurich for $14,700. The watch is limited to 48 pieces. The number stands for the place where the Grand Cœur comes to life and where the heart of the Grand Cœur first beat - in the Atelier at Tödistrasse 48 in Zurich.
