AIS  

AIS Collective was established in Zurich, Switzerland in the early 2020s as a dedicated watch care brand, born from the idea that a watch is not just an object but a finely engineered instrument that lives with its owner.
After around 18 months of research and development, the brand introduced its first Swiss‑made products such as the ChronoPen, later expanding into tools like the ChronoLeatherPen and complete care kits, allowing collectors to clean their watches safely at home at a standard that matches high‑end watchmaking
