Ultra-amplitude:

pushing mechanical limits

Dominique Renaud has already pushed the boundaries of the regulating organ under extreme conditions, demonstrating his spirit of exploration and invention. His explorations have shown that it is possible to break away from conventional watchmaking standards and rethink the way a balance wheel interacts with its escapement.

The Pulse 60 explores the uncharted territory of low frequencies, featuring the lowest frequency found in contemporary mechanical watchmaking: 1Hz. Its balance wheel oscillates just 60 times per minute – the same frequency as a human heart at rest. This exceptional frequency reduces the number of impulses and shocks to the escapement, thereby limiting the disturbances that disrupt the balance wheel’s movement. The seconds are marked by a single oscillation of the balance wheel, around which the rest of the movement is organised.

A large balance wheel to master the second

In the Pulse 60, the construction of the balance wheel, plate and escape pin assembly has been completely redesigned to allow an amplitude of over 360° without rebattement, something that was impossible in a traditional design.

More than just a feat of geometry, this amplitude has a direct impact on how the balance wheel is regulated, as it remains free for longer and over a greater distance. During this extended period, its movement is governed by its own dynamic laws, rather than by interactions with the escapement, which helps to make the timekeeping more stable and less sensitive to micro-variations.

Consequently, the number of disturbances experienced by the balance wheel is reduced to a minimum. The remarkable stability that results brings the watch’s behaviour closer to that of an ideal oscillator.
