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
A see- through caseback allows a glimpse of the automatic movement with each personalized rotor featuring the Les Clefs d’Or insignia plus the name & membership number of the concierge.The movement is specially made to our quality standards by Concepto. 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

Monday Motivation? Buy a new car! Welcome to the MDM Family INEOS GRENADIER Fieldmaster #035! 🌍
We were looking for a long time for a replacement for our old Landy, which unfortunately was no longer fit enough for the wild everyday life of watch lovers in Zurich...:-) He had this & that… and at some point we didn’t want to torture him anymore.
If you love the old Landrovers, you will eventually come to the INEOS Grenadier. The worthy successor to the original Landrovers. At first we were a bit strange. But once you have sat in this car, you are spoiled for other cars.
With him we can drive everything to our events and even the smallest watch boutiques he moves through the city and Switzerland as if they were nothing. And now we come to the quality and the mechanics – typical for watch souls: terrific!
He will now be embellished a bit and then he will drive through Zurich, bringing watches, hollowing watches, Totoro will stick his nose out of the window and it is often like in the old days, when Daniel drove through the city, many waved, conversations arose, watch fascination that jumped like sparks from one to the other. See you...

We did it! We were part of the SÄCHSILÜÜTE 2025! ⛄️💥 We can say that we are very attached to Zurich. It is our home. Zurich is the heart of our brand. Zurich is both an inspiration and a challenge.
With the Sächsilüüte, however, we have come even closer to Zurich. Not only did we create the official Sächsilüüte watch together with the ZZZ. We were also invited by Urs Bucher to walk with the @zunft_zu_wiedikon . An incredibly intense experience. 🌈💐🌸
We look back on the Sächsilüüte with our arms full of flowers and our hearts full of emotion. Thank you to everyone who experienced this day with us.
Massimo, Leonard, Masha
and the whole Dreifuss family

Welcome “Züri Date” SÄCHSILÜÜTE⛄️💥
The only mechanical watch that speaks Züridüütsch, from the only watch manufacturer in Zurich. A mechanical watch could not be more Zurich. But the Züri-Date SÄCHSILÜÜTE is even more.
She not only speaks the language of Zurich,
but also remembers the most important day in Zurich. The Sächsilüüte. As this always takes place on Mondays, SÄCHSILÜÜTE is written where MÄNTIG is usually written. And at 6 pm on the dot, the Böögg appears on the dial. As befits a Zurich watch, all of this is made here in Zurich with an automatic movement in the traditional craftsmanship. Now available online and in our workshop.
#MauriceDeMauriac #MDM #Sächsilüüte #uhr #watch #böögg #zurich #spring #festival
The Böögg now has its own watch! ⛄️💥
Together with the Central Committee of Zurich’s guilds, we have designed a timepiece especially for Sechseläuten.
Time plays an important role at Sechseläuten. When the churches in the old town chime at 6 p.m. sharp, the Böögg is on its way out. The shorter it takes for his head to explode, the better the summer will be. We took this as an opportunity to launch a clock together with the Central Committee of the Zurich Guilds (ZZZ).
