History

Reguladora began on 15 February 1892 as A Boa Reguladora in Vila Nova de Famalicão, Portugal. It was founded by João José de São Paulo, a watchmaker from Porto, and José Gomes da Costa Carvalho of Mouquim. The venture was created to develop watch manufacturing in Portugal and became an early domestic producer of mechanical timepieces. In May 1893, the company obtained a patent covering improvements to a standard mechanical movement and received a six-year privilege connected with that invention. It also opened its first workshop in Porto in 1893. The following year, the company won a gold medal at the agricultural and industrial exhibition of Vila Nova de Gaia. The early partnership changed after João José de São Paulo died on 11 July 1895. José Gomes da Costa Carvalho then invited his brother Lino de Carvalho, a watchmaker, to join the business. The brothers moved production to Vila Nova de Famalicão, a decision that helped reduce operating costs and created the basis for the company's long-term association with the town. The railway was important to the company's development because it supported the distribution of finished products and connected the factory with wider markets. Reguladora became more than a watch workshop. From 1903 it supplied electricity for street lighting in the village. In 1907 it built a steam power plant and became the concessionaire for supplying public and private lighting in Vila Nova de Famalicão. Its industrial activities also included mechanical carpentry and a sawmill. The factory expanded significantly in the early twentieth century: by 1914 it employed 220 workers and produced 6,408 timepieces per year. In 1923 the company received a gold medal at the international exhibition in Rio de Janeiro. That same year it built a new facility in Vila Nova de Famalicão. The building later became an important element of the town's industrial heritage. The company also created a workers' neighborhood, chapel and social center. These facilities reflected a paternalistic industrial model and anticipated similar employer-supported developments that became more common in Portugal during the 1950s and 1960s. The factory and associated structures helped make Reguladora a significant local institution as well as a manufacturer. Over time, the company developed a wide range of timekeeping products. It made alarm clocks, wall clocks, table clocks and column clocks, as well as wristwatches and pocket watches. Its activities also expanded into equipment such as electricity and water meters. The catalogue included named clock collections such as Atenas, Camberra, Monaco, Santa Comba, Batalha and Fátima, together with numerous wall-clock and wristwatch references. The corporate ownership structure changed in the late twentieth and early twenty-first centuries. In 1992, Boa Reguladora became part of the Schlumberger group of companies. In 2001 it was acquired by Actaris. A later revival came in 2007, when three former employees restarted production under the name Regularfama in the old factory. The factory closed in 2012. The available reference does not document a subsequent operating company, current owner, or active official website, so the present commercial status of the Reguladora brand cannot be confirmed.
