CHRONO MODERN “BIG DATE” BLACK
MDM.330.ST.45.BIGDATE.BK
The Chrono Modern, the basis of this watch, represents the history of Maurice de Mauriac like no other and has already written hundreds of fascinating stories for the brand. It makes sense to let this Icone take the next step.
The “MDM BIG DATE” caliber was installed for the first time in our anniversary watch: the Big Date for the 25th anniversary!
It conceals a manufacture movement whose beauty is revealed by the visible back.

CHRONO – THE DARKER THE BRIGHTER

Modern
Our success is built on these watches! They are our classics, and may forever be called "Chrono Modern". Designed by Daniel Dreifuss, the 051015 dial gives both watch and owner a subtle dynamism. The dimensions of these watches and their clear edges leave no doubt - a "Chrono Modern" always adorns a strong arm. No matter whether on water, on land or in the air. Mechanically driven, of course, the "Chrono Modern" is modular in design and allows for unique customization. You will love it as it will love you.

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 ❤️
