In 1853 Société d’ Horlogerie à Waldenbourg was founded as a Swiss pocket watch manufacturing company in a joint effort by the community of Waldenburg, Switzerland in order to create work in their valley, whose location along the route between Basel and Geneva had substantially lost travelers when a new train connection was established between Basel, Olten, and Geneva. In 1859 steam train tycoons Gédéon Thommen and Louis Tschopp acquired the company and privately restructured it. Tschopp left the company a year later, at which time it was renamed Gédéon Thommen’s Uhrenfabriken. By 1905 their most popular item was a line of wrist watches branded “Revue,” so the company was commercially registered as Revue Thommen AG, a joint-stock company, to capitalize on this recognition. In 1916 they crafted the first aircraft chronograph for the Swiss Air Force, starting a long-term relationship as their primary aircraft cockpit instrument supplier from 1936 to 1943. Revue Thommen developed and supplied altimeters, airspeed indicators, vertical speed indicators, clocks, and the landing gear for the Swiss multifunction biplane EKW C-35, but were also commissioned to produce watches for the German Wehrmacht, Luftwaffe, and Kriefsmarine, creating a separate brand called Revue-Sport to do so. In 1945 Revue Thommen launched a pocket altimeter for alpine climbers, shortly followed by altimeters specifically for parachutists, and both continue to be produced today. In 2000 Revue Thommen AG granted a license to the Swiss company Grovana Ltd. for the manufacturing and marketing of the Revue Thommen wristwatch brand products, so Revue Thommen AG could focus solely on its aircraft instrument business, expanding to include more sophisticated electronic equipment including air data systems and helicopter searchlights. In 2012 GT Thommen Watch AG, the joint-venture partnership of Andreas Thommen, Roland Buser, and Christopher Bitterli, bought the intellectual property rights for the watch business from Revue Thommen AG and began revitalizing the brand in the Swiss wristwatch business. They appointed Swiss Initiative Limited (SIL) as sole license holder for production and worldwide distribution in 2015. Revue Thommen was acquired by Transas Group in 2012, a Russian technology company, which was forced to sell its shares to the Russian private investor Sistema in 2015. A decline of demand for mechanical aircraft instruments in the aviation industry and the fallout from the 2008 Recession also led Revue Thommen AG to restructure, and the name “Revue” was removed from the company name to clearly identify them as solely a supplier to the aviation industry. Rebranded as Thommen Aircraft Equipment AG by Sistema, it sold its mechanical aircraft instrument business to Sathom, a subsidiary of the French aircraft component MRO company Satori Sarl, in 2016. Sathom kept all manufacturing in Switzerland as a condition of receiving a license to continue the production and sale of mechanical aircraft instruments under the Thommen brand name, moving from Waldenburg to a larger, more modern location in Muttenz. Meanwhile Thommens Uhrenfabrik AG, as the watch manufacturing group is now known, continues to produce watches under the Revue, Vulcain, Buser Phenix, and Marvin brand names.
