AIS Collective Debuts at EPHJ 2025 with the ChronoPen: The new Standard in Swiss Watch Care
Last week, AIS Collective proudly exhibited at EPHJ 2025—the world’s premier trade show for high-precision watchmaking and Swiss microtechnology. Surrounded by some of the most respected suppliers and manufacturers in the Swiss watch industry, we showcased our full line of innovative watch care tools—including the ChronoPen, ChronoLeatherPen, ChronoCloth, and ChronoSphere.
The ChronoPen: A Game-Changer in Watch Cleaning
While each of our products drew attention, the spotlight was firmly on the ChronoPen, our Swiss-made luxury watch cleaning tool. Engineered for precision, safety, and elegance, the ChronoPen captivated a community that truly values craftsmanship, detail, and dedicated horological care.
From the moment we set up our booth, the interest was immediate. What began as passing curiosity quickly turned into hands-on product demos, in-depth conversations, and genuine excitement from watchmakers, manufacturers, restoration experts, and collectors. Their positive feedback and technical insights were not only energizing but also a powerful validation of our mission.
Sharing the AIS Collective Philosophy
At AIS Collective, we believe that luxury watches deserve luxury care—designed specifically for the unique needs of high-end timepieces. Our products are not generic cleaning solutions; they are purpose-built tools created by people who understand and live the world of horology.
The enthusiastic reception of the ChronoPen at EPHJ showed us that this philosophy resonates deeply within the industry. More than just a product showcase, EPHJ allowed us to share our values and commitment to raising standards in watch care.
