Greubel Forsey

Greubel Forsey is an independent Swiss haute horlogerie brand founded in 2004 by Robert Greubel and Stephen Forsey and based in La Chaux-de-Fonds. The company concentrates on a deliberately narrow field: technically ambitious, low-volume mechanical watches whose architecture, regulating systems and hand finishing are central to their identity. Its best-known work uses inclined or multiple tourbillons, but the brand has also developed GMT displays, perpetual calendars, striking mechanisms, constant-force systems and simpler watches intended to express its construction and finishing philosophy. The founders established their partnership through work on complicated movements. Greubel, who grew up in Alsace, France, began in his family’s watchmaking business before moving to Switzerland and contributing to complicated-watch development at IWC. He later became a prototypist, partner and managing director at Renaud & Papi, the specialist movement-development firm now associated with Audemars Piguet. Forsey, from St Albans in England, trained through clock restoration and watchmaking studies and also joined Renaud & Papi. The two began working independently in 1999 and founded Complitime SA in 2001 to develop complicated mechanisms for high-end watch companies. Greubel Forsey was introduced publicly at BaselWorld in 2004 with the Double Tourbillon 30° (DT30°). Its defining concept places a 30-degree inclined tourbillon cage inside a second cage, with the two rotating at different speeds. The arrangement was intended to reduce the effect of gravity on the regulating organ in different positions. Subsequent inventions expanded this approach into the Tourbillon 24 Secondes, Quadruple Tourbillon and related Invention Pieces. The company’s Experimental Watch Technology, introduced in 2005, provided an internal platform for testing mechanisms and developing ideas such as a spherical differential, constant-force transmission and specialized balance-and-spring systems. Although tourbillon watches remain a major part of the portfolio, Greubel Forsey has not treated the tourbillon as its only product formula. The GMT, introduced in 2011, combined a second time zone and a three-dimensional rotating globe with a tourbillon regulator. At the 2012 SIHH exhibition, the Double Balancier 35° became the company’s first model without a tourbillon. Other important projects include the QP à Équation perpetual calendar, the Grande and Petite Sonnerie striking watch, the Signature series and Hand Made 1, in which almost the entire watch is produced through hand-operated methods. Production is intentionally limited, with the reference material describing output at approximately 100 watches per year. The watches are positioned at the extreme high end of independent Swiss watchmaking and are recognized for complex movement design, unusual three-dimensional layouts, extensive hand decoration and scarcity. The company has also used selected collaborations and artistic projects to extend its identity beyond conventional time display, including a 2006 Opus collaboration with Harry Winston and Art Piece watches made with British micro-sculptor Willard Wigan. Greubel Forsey has received major industry recognition, including the Gaïa Prize for entrepreneurship, the Aiguille d’Or at the Grand Prix d’Horlogerie de Genève for the Double Tourbillon 30° and Tourbillon 24 Secondes Vision, and awards for chronometry and hand craftsmanship. In addition to commercial watchmaking, the founders support the Time Æon Foundation, which seeks to preserve endangered horological crafts, encourage training and help transmit specialist watchmaking skills to future generations.

Robert Greubel and Stephen Forsey developed their professional relationship at Renaud & Papi, where both worked on complicated mechanical movements. Greubel had earlier worked at IWC on grand-complication development after beginning his career in his family’s Alsace watchmaking business. Forsey combined clock restoration experience with formal watchmaking study in Neuchâtel before joining Renaud & Papi. Their shared work formed the technical foundation for the later Greubel Forsey approach. In 1999, the two began working independently, and in 2001 they established Complitime SA, a specialist company developing complicated mechanisms for high-end watch brands. This period allowed them to investigate mechanisms outside the constraints of a conventional product line. Their first major proprietary concept was the Double Tourbillon 30°, which used two nested tourbillon cages and an inclined inner cage. The system was designed to address positional timing variation caused by gravity while also creating a distinctive three-dimensional movement architecture. Greubel Forsey was formally launched in 2004 at BaselWorld with the Double Tourbillon 30°. In 2005, the founders created Experimental Watch Technology, an internal research and development platform for testing and validating new mechanisms. The company subsequently developed a family of tourbillon-based inventions, including the Tourbillon 24 Secondes and Quadruple Tourbillon, as well as the Invention Pieces that place the mechanism itself at the visual center of the watch. The brand broadened its technical vocabulary through the 2006 Harry Winston Opus 6 collaboration and through models such as the GMT, which combined a second time zone with a rotating globe. In 2012, the Double Balancier 35° demonstrated that the company could apply its design and finishing language to a non-tourbillon regulator. Other projects introduced perpetual-calendar indications, equation-of-time information, striking functions and single-watchmaker production concepts. Greubel Forsey’s production remains intentionally small. The company’s reputation rests on a combination of scarcity, complex engineering and hand finishing rather than on broad retail distribution or high-volume product families. Hand Made 1 exemplifies this strategy: the reference material states that about 95 percent of the watch, including its hairspring, is made with hand-operated tools and that each example requires approximately 6,000 hours of work. The founders have also supported the preservation of horological skills through the Time Æon Foundation. Its activities address endangered crafts, training and the transmission of independent watchmaking knowledge. Industry recognition has included the 2009 Gaïa Prize for entrepreneurship, the 2010 Aiguille d’Or for the Double Tourbillon 30° Édition Historique, the 2011 International Chronometry Competition and the 2015 Aiguille d’Or for the Tourbillon 24 Secondes Vision. Hand Made 1 later received the 2020 Grand Prix d’Horlogerie de Genève award for best men’s complication watch.
