Watch Specifications
Elegant Pushers
Here in the silver stainless steel version: The pushers are the direct contact between clockwork and man. The stop function can be started, stopped and reset. The smooth, unscrewed pushers give the watch a fine retro elegance. This is underlined by the high-curved glass, with which the watch slides very gently under cuffs VIEW ON-CHAIN-DPP
The watch is a symbol of innovation and exclusivity — representing eternity. Each purchase includes the certificate of authenticity, two-year standard guarantee, a credential card for the digital product passport (DPP), and the access to a Cardano-based DPP, powered by Tokenance. The lucky buyers will also find, inside the DPP, the opportunity to write an eternal message of love (text-based) to their most loved ones and record it on the Cardano chain. They will also be able to converse with a proprietary AI agent, incarnating Ms. Ada Lovelace.
Caliber C8100
A protective cover shields the anti-reflective sapphire crystal. Once opened, the movement beneath the glass is revealed – the watch comes to life.The C8100 movement is manufactured specially for us by Concepto, according to our high standards of Swiss watchmaking.
It is an automatic movement featuring hours, minutes, and central seconds, a hacking mechanism, Etachron fine adjustment with eccentric regulator, 28,800 vibrations per hour (4 Hz), 25 jewels, and a power reserve of 44 hours.
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 it 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 favour 316L stainless steel. The darker, the brighter
Super-LumiNova is a brand name under which strontium aluminate–based non-radioactive and non-toxic photoluminescent or afterglow pigments for illuminating markings on watch dials, hands and bezels, etc. in the dark are marketed. This technology offers up to ten times higher brightness than previous zinc sulfide-based materials. When the luminescent pigments were stimulated by daylight or artificial light, they give off the light energy in the dark for several hours. This gives the watch extremely good legibility even in the dark. 1

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.

Enjoy the magic of @polarzauber.ch with us! 🎄❤️
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.

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.
