Watch Specifications
Screw-down pushers
Screw-down pushers grant an additional mechanical aspect to watches. In order to operate the stopwatch function, one has to first unscrew the collar then close it again after stopping it. The crown is always decorated with an M.Chrono, screw-down pushers, caseback
Our display back case uses a blue anti-reflective sapphire crystal and thus allows 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.Chrono – the darker the brighter
Superluminova is a phosphorescent phosphor, and free of radioactive additives. Superluminova is a hundred times brighter than other inactive luminescent pigments. When the luminescent pigments have been excited by daylight or artificial light, they release the absorbed light energy over several hours in the dark. This gives the watch extremely good clarity even in the dark.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 unidirectional 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 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 yearsTOP Execution

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 its 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
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.

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.
