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.

Made by Zurich – loved by Portofino 🇮🇹⛵️
We only work with selected retail partners. Such contacts often arise in places where our family members like to spend a lot of time. Portofino is one of these places. And now what belongs together has come together: Maurice de Mauriac and Gold for Ever by Valentina Cattaneo and a selection from our L series, which she offers to her customers there. Gold for Ever is also a family business - the chemistry is right and everyone knows the opportunities, challenges and passion of the other. We are delighted to be represented in this wonderful place.

We wish you all the best Finn.

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...
