classic simple pushers
Non-screw pushers or just simple pushers as we call them are smooth and make for a sleeker appearance. The stop function is activated simply by pressing down on the pusher. Chrono classic, 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 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 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

Fridays for Future!!! ⚙️✨
Our passion for watchmaking is built on precision, craftsmanship, and passing knowledge on to the next generation.
At just 22 years old, Sean is already part of our team of watchmakers — and today he had the opportunity to introduce two interested students to the fascinating world of haute horlogerie. 🔍
From intricate movements and traditional craftsmanship to the passion behind every tiny detail, it was inspiring to see the curiosity and enthusiasm of these young visitors.
Because true craftsmanship lives on when it is shared. Perhaps we already met the watchmakers of tomorrow.
