An introduction to the remontoire

The remontoire is a mechanical device in watchmaking designed to address the issue of constant force, which affects the accuracy of timepieces. It consists of a secondary spring that applies a consistent torque to the balance and escapement mechanism, ensuring more stable timekeeping. The concept of the remontoire dates back to 1595, when Swiss clockmaker Jost Bürgi invented the gravity remontoire, which utilized a falling weight to wind the spring. Later, in 1739, John Harrison developed the spring remontoire, which is powered by the mainspring. Despite advancements in horology that have reduced the necessity for remontoire mechanisms, they are still appreciated for their craftsmanship and historical significance. Modern brands like F.P. Journe and Arnold & Son incorporate remontoire in their designs, showcasing the intricate mechanics that appeal to enthusiasts. While the functional benefits of a remontoire in contemporary watches may be marginal, its aesthetic and historical value continues to captivate watchmakers and collectors alike.
