Sellita was founded in 1952 in La Chaux-de-Fonds. The company manufactured their own-branded watches under the advertising slogan, "une montre a la hauteur" ("a watch up to the task"). Sellita was co-located with Montres Erguel S.A. at Rue des Tourelles 13 before moving to Rue Numa-Droz 158 in 1954. This would be home to Sellita as the company grew through the 1960s.
