The story that haunts this land
Neuchâtel becomes the heart of Swiss watchmaking from 1679, when Daniel JeanRichard founds the first watch workshop in the Jura mountains. Place Pury, inaugurated in 1788 in honor of State Counselor David-Louis de Pury, welcomes you to the center of this mechanical revolution. The bourgeois buildings of the 18th century surrounding it housed the watch merchants who already exported to London and Amsterdam. Your mission begins here: find traces of Breguet's lost technical manuscripts, hidden in the city's monuments by his network of Swiss correspondents.
The Collégiale des Grands-Sonnetiers, built between 1499 and 1540, houses in its side chapel the tomb of Abraham-Louis Breguet (1747-1823), the most famous clockmaker in history. Its Gothic tower of 62 meters, visible from 20 km away, served as a landmark for watch merchants converging on Neuchâtel. The ancient mechanical clockwork elements integrated into its design testify to this early vocation. Pierre Jaquet-Droz (1709-1790), inventor of automatons that still fascinate today, prayed here before each major creation.
Neuchâtel Castle, residence of the Princes since 1214 and current seat of the cantonal government, hides sundials from the 18th century on its west facade. These time-measuring instruments precede the rise of Neuchâtel mechanical clockmaking. In its inner courtyard with Gothic arcades from 1459, clockmakers came to present their innovations to the prince-protectors of their art. The 15th century renovations already integrate niches intended for monumental clocks.
The Neuchâtel Cantonal Observatory, founded in 1820 by Daniel Huber, develops the precision astronomy essential to clockmakers. Its historical instruments, including a meridian from 1825, allow watches to be set to astronomical time. The Museum of Art and History, installed in the former hotel of the Lords of Neuchâtel from the 16th century, preserves 4,500 clockwork pieces, including Pierre Jaquet-Droz's automatons. This collection traces three centuries of Neuchâtel technical innovation.
Your journey in the shadow of celestial mechanics reveals how Neuchâtel became the Swiss capital of watchmaking through the unique alliance between artisanal know-how, technical innovation and European commercial network. From Quai Philip Godet, former quai du Peyroux where watch trade transited in the 18th century, to the neoclassical Town Hall by Louis Levade (1784-1790), every stone tells this mechanical epic. You leave with the secrets of master clockmakers and understanding of this UNESCO heritage that still makes Switzerland's heart beat.
