L2 STEEL DEEP ARCTIC
MDM.L2.FLST.BE
design by Fabian Schwaerzler
“Maurice de Mauriac has invested years in the development and manufacture of professional diver’s watches. This ‘L2’ style is crafted from 316L stainless steel – one of the hardest and most resistant in the world – 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.”

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 – both below and above water – 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.
Before we look forward we look back with our TIMEpaper. Full of stories of the last years.

Mastering Holiday Season Style with the L3 Small Seconds✨1x watch - 6 colors - 1000 ways to wear.
A watch that is launched directly with six colours does not expect you to match the watch. It wants to match: black, white and cherry blossom as well as spherical blue, spherical green and spherical burgundy (a first in our colour palette) make the L3 Small Seconds look like six different watches. Complemented by a brushed stainless steel case or a DLC-coated stainless steel case for a darker look, their elegance is very attractive to many. Combined with a leather or Milanese strap, even crossover with a Nato strap, almost anyone can get the watch that suits them perfectly.

Time is Love ❤️👀
At Christmas, time slows down. It becomes warmer. More attentive. More human.
Our father lived with passion. When he loved something, he stayed loyal to it. What mattered to him was never a logo or a label, but the feeling behind it. Colour. Energy. Consistency. Love, lived every day.
There is a small heart that has accompanied our family for many years. For us, it became a quiet symbol. A reminder to follow your heart, to stay compassionate, to think clearly, to live with colour and to remain open to the world.
Christmas reminds us of exactly that. Loyalty. Presence. The courage to care.
Time is not measured in minutes these days. It is measured in shared moments, familiar gestures and the people we choose to love.
Time is Love.

We loved the idea of being able to go to the Christmas market without having to worry about whether the weather would allow it or not. That’s why we’re part of the Christmas market in Zurich’s central station hall this year.
We cordially invite you to share the special atmosphere of this market with us. Let’s breathe in the Christmas air together, enjoy the special atmosphere of this hall, and have what matters most—a good time.
You can also get the big MDM newspaper 2026 from us here. Why are we emphasizing this so much? Come and get it, then you’ll know.
See you later!

Concept stores are very special places in themselves. So we present ourselves there in a very special way. With the smallest watch boutique in the world. You can “talk” there with the concept watches from our City Date collection. And gaze at other watches that simply stare back at you in a relaxed manner.
