The Paul Forrest manufacture is located within the Val de Travers in Fleurier, Switzerland — a small village known for its haute horlogerie history. It is here that the exceptionally small mechanical movement, Caliber PF-001 that powers the motion of the hearts is crafted. This exclusive movement is built to precisely power the patented, poetic beating heart.

The heart is brought to life (via the hidden mechanical movement) by an integrated winding key that is, in itself, a complex work of art. Comprised of many individual components the key and its one-way ratcheting system for easy winding, is referred to by Paul Forrest as the “key to your heart”.

The jewelry pendant is crafted in Switzerland as well using only 750 (18-karat) Gold. Each pendant features a double curved, anti-reflective sapphire crystal aperture, which is the window to the mesmerizing beating heart. Naturally, because at the soul of the pendant there is a unique mechanical movement, each pendant is water resistant to 5 atm.

The movement has been specially built to transmit force to a specially designed cam which rotates at 0.8 times per minute. This cam is covered with a thin layer of Teflon (PTFE) to reduce friction. The cam moves vertically a ruby pin integral with two arms which are pivoted symmetrically with respect to a vertical plane. This gives the heartbeat symmetry. The two heart lobe supports are fixed on the two arms. Two rods are fixed between an arm and the opposite lobe support and guide lobes to guarantee a constant spacing between the two lobes, and balance the system. A mass is attached to one of the two arms to balance the system in a vertical position.This complex device converts a circular movement into a translational movement of two elements symmetrically with minimum effort due to a balancing of the weight in each operating position.


Each component and its materials are selected to guarantee top performance and aesthetic beauty.
