Watch Specifications
Silvern screw-down pushers
Screw-down pushers confer an additional mechanical aspect to our watches. In order to operate the stopwatch function, you have to first unscrew the collar and, then, close it again after stopping it. Silver Chrono , screw-down pushers, caseback
Our display back case uses a blue anti-reflective sapphire crystal and thus allow for an unobstructed view of the pulsating calibre. One has the feeling that the soul of the mechanical automatic movement can both be felt and seen. The watch is alive. Together with the possibility of the custom labelled rotor, each watch becomes a truly personal gift – even to oneself. ETA 7750 Movement
After the takeover by ETA, the Valjoux 7750 was re-named the calibre ETA 7750. This is quite possibly the most successful automatic chronograph movement of all time. The calibre stands out due to its high degree of accuracy and robustness. It has 25 stones, a ball bearing mounted rotor and a uni-directional winding mechanism. The 7750 has a 1/8-second counter, a 30-minute counter, a 12-hour counter, 28,800 half oscillations per minute and has a power reserve of ca. 44 hours. The loss of accuracy is 1-6 seconds per day. Movement revisions are recommended every 3 to 8 years-TOP Execution

Stainless 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. 1

Modern
Every company has the mystique of its first employee, its first premises, its first product. The Chrono Modern is the founding mystique that has become a watch. It was the first "real" Maurice de Mauriac. What was revolutionary at the time was the dial designed by Daniel Dreifuss, which we now call the 0510 dial. The numbers from 0 to 55, rather than 1 to 12, indicated the time. The minutes are more important than the hours. An expression of the agility of its wearers. Since women also love this potent statement of time on their arms.

Mastering Holiday Season Style with the L3 Small Seconds✨1x watch - 6 colors - 1000 ways to wear.
A watch that is launched directly with six colours does not expect you to match the watch. It wants to match: black, white and cherry blossom as well as spherical blue, spherical green and spherical burgundy (a first in our colour palette) make the L3 Small Seconds look like six different watches. Complemented by a brushed stainless steel case or a DLC-coated stainless steel case for a darker look, their elegance is very attractive to many. Combined with a leather or Milanese strap, even crossover with a Nato strap, almost anyone can get the watch that suits them perfectly.

Time is Love ❤️👀
At Christmas, time slows down. It becomes warmer. More attentive. More human.
Our father lived with passion. When he loved something, he stayed loyal to it. What mattered to him was never a logo or a label, but the feeling behind it. Colour. Energy. Consistency. Love, lived every day.
There is a small heart that has accompanied our family for many years. For us, it became a quiet symbol. A reminder to follow your heart, to stay compassionate, to think clearly, to live with colour and to remain open to the world.
Christmas reminds us of exactly that. Loyalty. Presence. The courage to care.
Time is not measured in minutes these days. It is measured in shared moments, familiar gestures and the people we choose to love.
Time is Love.

Concept stores are very special places in themselves. So we present ourselves there in a very special way. With the smallest watch boutique in the world. You can “talk” there with the concept watches from our City Date collection. And gaze at other watches that simply stare back at you in a relaxed manner.
