What is a spherion?

In 2016, after 17 years spent studying the tourbillon, Jonathan Purnell and the genius watchmaker Eric Coudray managed to develop and manufacture the first Spherion. Unlike a Tourbillon, a Spherion does not rotate on one axis with a linear path, it rotates on multiple axes with its balance wheel trajectory drawing a sphere.


“The power of the Spherion movement is unrivalled in this industry, it is tantamount to a highspeed Formula1 car racing at 400km/h without needing a pit stop.”

Maurizio Mazzocchi, CEO of Purnell

Brand Heritage



Inspired by performance, precision and mechanical prowess, Purnell is doubling down on its philosophy of bringing more future than past to watchmaking. Since its founding in 2020, Purnell has made its mark on the landscape of contemporary high watchmaking, not only with its unmistakable Spherion but also with a manufacturing process integrated locally in the Vallée de Joux all the way to the brand’s new headquarters on Rue du Rhône in Geneva, which includes a refined showroom to welcome clients. Purnell makes a vow to only create tourbillon movements. Celebrating 220 years of its creation, the tourbillon is a defining chapter in the story of watchmaking, and Purnell intends to make its Spherion an equally defining moment in the complication’s story.


For this, the brand partnered with the Mozart of multi-axis tourbillons, Eric Coudray, winner of the 2012 Prix Gaïa and inventor of the Spherion and Double Spherion, the engine of the Escape Primo and Escape II collections. A world premiere, the Spherion is the world’s fastest triple-axis tourbillon, each cage rotating in 8, 16 and 30 seconds respectively. The power of the Spherion movement is unrivalled in this industry, it is tantamount to a highspeed Formula 1 car racing at 400km/h without needing a pit stop. From the world’s fastest-triple axis tourbillon to exclusively 100% Swiss Made materials, Purnell keeps striving for the best, creating the Watchmaking Coolture while staying faithful to true watchmaking craftsmanship.
