The crown is the immediate connection between the movement and the owner. It is therefore easy to grip and can be turned precisely, so that the watch can be set with great ease. Thanks to the highly domed sapphire crystal, the watch glides very smoothly under cuffs.

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
Superluminova 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 legibility even in the dark. The golden keys of Les Clefs d'Or

L-Series
Fabian Schwaerzler, Swiss designer and as such purist, has chosen the line as a design element and thus designed the L-series, the line series, from the Bauhaus era into the present. They have become icons of watch design. His design allows the watches to be discreetly present, but also to fill the space. Follow the line. It will show you the beauty of time.
IT‘s TIME for our ambassador @leuppisamir for the ESAF 2025 (Eidgenössisches Schwing- und Alplerfest

This week is about our father and (actually Massimo’s) partner in crime 🐾🩷. About how he would go everywhere with Totoro, to the mountains, to sit with an espresso in the hand or simply to spend hours just being near him. These small moments became big memories. We hold on to the colors, the love, and the gratitude of time shared. #dad #RIP #dog #internationaldogday #father #partnerincrime #mauricedemauriac #mdm #totoro #watches #watchdog #love #family #time #zurich #colors

A day to reflect on watch magic ✨
Two years ago today, something new began because something old had come to an end - without anyone looking for it. Massimo, Leonard and Masha lost their role model for what they are today: the movers and shakers behind MDM.
Daniel Dreifuss was suddenly missing not only as a family man and brand founder, but also as a great watch wizard, and the magic threatened to end.
Today, two years on, there are three watch wizards - and the magic has tripled.
In this time, three times as many watches have been developed, three times as many sold, and the magic still fascinates. It doesn’t always have to be the big moment when something dramatically disappears. It is the small magic that touches.

A little story on Sunday: It all started with a parcel that wasn’t delivered...A Portuguese customer’s new watches were not delivered by the parcel service. The parcel began an odyssey and at some point we decided that one of us would take it to Cascais personally.
Of course, you then call Portuguese friends to meet up. Miguel Seabra is one such long-time friend. Miguel, a watch enthusiast, immediately calls a few more watch lovers and we sit together on the beach in Cascais and talk watches and philosophize.
At moments like this, our family expands to include people who share a special love.
…And the conclusion of the story: something good can also come out of something bad.
Happy Sunday everyone - TIME IS LOVE ❤️
