Watch Specifications
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. 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.

The Dialectic Zug Open 2025 has been decided. We, who like to talk about ourselves, would simply like to congratulate the winner Lukas Klein on his victory. This is his second Challenger title in two weeks. We are very proud to have been able to accompany him on this journey.
It was Leonard who presented him with his personal Dialectic Zug Open watch.
Thank you for being part of the excitement, thank you for the great moments we had on site. We remain loyal to tennis and hope to see you again somehow.

Dialectic Zug Open has its best time: ours!
As Official Time Keeper, you have to be convinced of this even before the tournament. Now we’re here, feeling the vibes of the tournament and we know it’s for real. The weather could have been a little kinder. But even that can’t take the smile off the faces.
