Peter Speake-Marin

Peter Speake-Marin^[3] (English) studied watchmaking at London's Hackney Technical College and continued his horological education at the Swiss watchmaking school WOSTEP.

For seven years Speake-Marin was head of the antique watch section at Somlo Antiques in London. He moved back to Switzerland in 1996 when recruited by Renaud & Papi (now Audemars Piguet Renaud & Papi SA) to develop and build high complications.

In 2000 Speake-Marin established his own atelier where he designs and creates his own Speake-Marin watches. In 2006 he worked on the Excenter Tourbillon with Harry Winston.^[4] In 2007 he collaborated with Christophe Claret and Roger Dubuis to develop Chapter One for Maîtres du Temps.

Christophe Claret

Christophe Claret^[5] (French) attended the watch school in Geneva and, upon graduation in 1987, worked alongside Roger Dubuis in the latter's atelier, and then with Dominique Renaud and Giulio Papi (now Audemars Piguet Renaud & Papi SA). In 1987 he formed his own company, Christophe Claret SA, in Le Locle, Switzerland.

Claret specializes in designing, manufacturing and assembling very complicated watches for Swiss watch brands in his comprehensively equipped, state-of-the-art workshops. He is particularly known for his chiming watches.

In 2005, Claret co-founded the ultra-high-end watch brand, Jean Dunand, with Thierry Oulevay.^[6] He collaborated with Roger Dubuis and Peter Speake-Marin at Maîtres du Temps to develop Chapter One, which was presented in Geneva in 2008.

Roger Dubuis

Roger Dubuis^[7] (Swiss) worked with a local watchmaker as a young teenager before studying at the Geneva Watchmaking School.

After 14 years of developing and restoring high complications at Patek Phillipe, Dubuis founded his own restoration and repair atelier in 1980. He co-developed, with Jean Marc Wiederrecht, the world's first perpetual calendar bi-retrograde movement for Harry Winston.

In 1995 Dubuis co-founded the watch brand Roger Dubuis SA^[8] with Carlos Dias. The two founders no longer have any affiliation with the brand, which is now majority owned by the Richemont Group.^[9] With Maîtres du Temps, Dubuis collaborated with Christophe Claret and Peter Speake-Marin to develop Chapter One, which debuted in Geneva in 2008.

Daniel Roth

Daniel Roth^[10] grew up in Nice in the south of France. He studied watchmaking there and then moved to Switzerland to further his horological education. After learning traditional watchmaking techniques at Audemars Piguet he became the master watchmaker at Breguet. The year was 1970, and the Chaumet brothers had bought Breguet, at the time virtually dormant, with the intention of reviving the brand.

After 14 years at Breguet (watch), a period in which he is credited with introducing what is now considered the "Breguet look" Roth left when the brand was sold. In 1989 he launched his own brand, Daniel Roth (sold to the Bulgari group in 2000). Roth now handcrafts traditional two-minute tourbillons under his new brand, Jean Daniel Nicolas.
