The golden keys of Les Clefs d’Or
These concierges are only found in first-class five-star hotels and can be recognised by the crossed keys on their revers. Until now. From now on, these insiders will be increasingly recognisable by their exclusive watch – the Maurice de Mauriac L3 Les Clefs d’Or. This watch is exclusively reserved for members of Les Clefs d’Or.

STRAP SELECTION
Discover our exclusive selection of watch straps that combine maximum comfort and individual design. Choose between a handcrafted Barenia leather strap - available in the finest blue, warm cognac, elegant black or seductive dark chocolate brown - and an elegant stainless steel Milanese. Each strap is crafted with the utmost care and makes a stylish statement on your wrist. 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 Engraving

It is a automatic movement with hours, minutes and sweep second. Second stop device, eccentric fine adjustment Etachron, 28,800 vibrations per hour, 4 Hz, 25 jewels.
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. The golden keys of Les Clefs d'Or

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 ❤️
