Peter founded Speake-Marin SA in 2002 in Bursins Switzerland. Peter Speake-Marin’s first wristwatch was the Piccadilly. Various Piccadilly series and unique pieces have been created since, the first of which was the Original Piccadilly featuring enamel dial. The Piccadilly case features screwed lugs, pleated crown and a drum-like case shape, which was inspired by the movement holders. Launched in 2009, Marin 1 Mk I was the first Speake-Marin model to feature the SM2 calibre, an in-house calibre, designed and manufactured by Speake-Marin. It took three years to develop SM2 movement. In 2006 Peter Speake-Marin worked on the Excenter Tourbillon with Harry Winston. He was then a consultant with significant involvement in the development of movement and case, as well as responsible for final quality control, for MB&F's Horological Machine No.1, delivered from 2007. In the same year, he collaborated with Christophe Claret and Roger Dubuis to develop Chapter One for Maitres du Temps. In 2009, with Daniel Roth, he developed Chapter Two for Maîtres du Temps. Peter Speake-Marin left the company in 2017 and was replaced by the actual CEO, Christelle Rosnoblet (already administrator since 2012), and an owner of the company. In 2019, the headquarters were moved from Bursins to Geneva.
