Room 407, the old Post Office building, Le Locle. A room entirely devoted to the uniquely talented Jules Grossmann. A room that looks back to the early days of training in watchmaking, and forward to the future with the institutions that continue to safeguard learning, excellence and innovation. A room where careers are born.

The Watch Academy foundation and the Musée d’horlogerie du Locle — Château des Monts invite you to open the door of room 407. In 1868, a dozen pupils did exactly that. They were the very first class to study at the Le Locle Watchmaking School, under Jules Grossmann. But the classroom represents much more than an historical figure. It reminds us that Le Locle’s avant-garde spirit shaped its destiny. And that an entire region dared to break new ground. Echoes of this defining period can be found in the quartz crisis of the 1970s, when training and excellence took the form of innovation and diversification. This belief in quality is now part of Switzerland’s cultural heritage – yours to discover when you open the door of room 407...
