L2 STEEL DEEP ARCTIC
MDM.L2.FLST.BE
design by Fabian Schwaerzler
âMaurice de Mauriac has invested years in the development and manufacture of professional diverâs watches. This âL2â style is crafted from 316L stainless steel â one of the hardest and most resistant in the world â and equipped with a helium valve to release excess pressure when diving below 300 metres. It has large luminescent indices and an ETA 28.24-2 movement which will stand the test of time.â

L2 STEEL, HELIUM RELEASE VALVE
During extreme diving situations, helium atoms make their way into the watch. As such, the process of decompression could dislodge the watch crystal. The helium release valve prevents this from occurring by allowing the excess pressure to escape via the valve, due to this special valve, it is possible to dive below 300 meters. L2 IN STEEL, CASEBACK
A watch like a lion, a sea lion. What animal is closely associated with people and is known for its skillful ability to dive to great depths? The sea lion. The backside of the L2 is adorned with this magnificent creature, whose maneuverability, elegance and function is attuned to life underwater. Represents a diving watch blending all of these traits. Given that the lion is the symbol of Zurich, the city that has shaped the evolution of this watch, it seems only appropriate that the sea lion should be the symbol of the Maurice de Mauriac L2. A roar â both below and above water â has been sent out from Maurice de Mauriac throughout the world. CALIBER ETA 28.24-2
ETA 28.24-2 is one of the most famous Swiss watch movements.TOP Execution

STEEL
Not all steels are created equal. We use 316L stainless steel; one of the hardest premium steels in the world. In addition to its hardness and resistance, this high-quality steel stands out because of its finish as well as its very fine silver hue. 316L steel has a significantly lower nickel emission than, for instance, 904L steel, which is also a high-strength steel alloy. This is, for us, a reason to favor 316L stainless steel.L2 THE DARKER, THE BRIGHTER
Super-luminova is a phosphorescent phosphor, and free of radioactive additives. Superluminova is a hundred times brighter than other inactive luminescent pigments. When the luminescent pigments have been excited by daylight or artificial light, they release the absorbed light energy over several hours in the dark. This gives the watch extremely good clarity even in the dark. 1

L-Series
Fabian Schwaerzler, Swiss designer and purist, has chosen the simple line as the core, clean, minimal design element and thus gave birth to the L-Series. Connecting the line series from the Bauhaus era, to the present Icons of watch design they have since become. His minimalist design allows the watches to be discreetly present, yet in addition, fill the void. Follow the line. This series will show you the beauty of time.

WE ARE READY FOR SUMMER âïž
Summer is our favorite season, so of course we had to bring out all the colorful straps and accessories ;)
And yes⊠the finish flag window was a mustđ . #mauricedemauriac #natostraps #zĂŒrich
Fridays for Future!!! âïžâš
Our passion for watchmaking is built on precision, craftsmanship, and passing knowledge on to the next generation.
At just 22 years old, Sean is already part of our team of watchmakers â and today he had the opportunity to introduce two interested students to the fascinating world of haute horlogerie. đ
From intricate movements and traditional craftsmanship to the passion behind every tiny detail, it was inspiring to see the curiosity and enthusiasm of these young visitors.
Because true craftsmanship lives on when it is shared. Perhaps we already met the watchmakers of tomorrow.
