silvern screw-down pushers
Screw-down pushers grant an additional mechanical aspect to watches. In order to operate the stopwatch function, one has to first unscrew the collar then, close it again after stopping it. The crown is always decorated with an M.Moon with screw-down pushers, caseback
Our display back case uses a blue anti-reflective sapphire crystal and thus allows for an unobstructed view of the pulsating caliber. One has the feeling that the soul of the mechanical automatic movement can both be felt and seen. The watch is alive. Together with the possibility of the custom labelled rotor, each watch becomes a truly personal gift – even to oneself. Moonphase 7751 movement
The mechanical automatic caliber ETA 7751 has been produced for chronographs since 1986 and has since then been continually refined. The mechanical moon phase indicator is the caliber’s distinguishing feature. The moon phases can be changed via the quick adjustment feature on the side of the case.TOP Execution

Steel with M-crown
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. The crown is always decorated with an M.1

Modern
Our success is built on these watches! They are our classics, and may forever be called "Chrono Modern". Designed by Daniel Dreifuss, the 051015 dial gives both watch and owner a subtle dynamism. The dimensions of these watches and their clear edges leave no doubt - a "Chrono Modern" always adorns a strong arm. No matter whether on water, on land or in the air. Mechanically driven, of course, the "Chrono Modern" is modular in design and allows for unique customization. You will love it as it will love you.

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!
Massimo, Leonard, Masha
and the whole Dreifuss family
Enjoy the final supermoon of 2025 🪩 - with the matching watch.

Carlos Leal lives life at his own pace – with our watch
Musician, actor, nomad: Leal doesn’t think in terms of categories, but in terms of movement. Growing up in Lausanne as the son of Spanish immigrants, he experienced the tension between family warmth and Swiss precision from an early age – a tension that shaped his creativity.
As a hip-hop artist with Sens Unik, he made his mark on the sound of the 1990s. Leal continued to follow his inner rhythm – into acting. Snow White was his breakthrough, followed by international productions such as Casino Royale and engagements in Hollywood.

A border crosser with a sense of rhythm – Carlos Leal
Some people wear time like an accessory. Others feel time as an inner pulse – rhythm, attitude, energy. Carlos Leal is one of the latter.
His path is not a straight line, but an elegant curve through life – sweeping like the hands of a watch. It is precisely this attitude that connects him to us and our watches. Carlos wears our moon phase not as a status symbol, but as a companion to an attitude: attentive, curious, always on the move. An artist who doesn’t measure time, but lives it – and thus fits in perfectly with us.

Events
BERN POP-UP
15 .09 – 31 .12
Location: Uhrsachen, Theaterpl. 1, 3011 Bern, Switzerland
In Switzerland, Swiss watches are not particularly striking. Unless, of course, it’s a watch that speaks to you in the Swiss dialect. We’ll be showing you this watch and other horological surprises at our pop-up store in Bern!
THRYVE Concept Store
01 .10 – 01 .02
Location: Bärengasse 16, 8001 Zurich
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.
