In 1892, watchmaker Léon Breitling, after starting out in a small workshop in Saint-Imier and concentrating all his attention on chronographs, succeeded in expanding his business by opening a factory in La Chaux-de-Fonds. And it was there, exactly twenty years ago, that Breitling decided to live up to its commitment to quality and precision. The result is the Breitling Chronométrie, the heart of the company's savoir-faire and innovation since 2001. An ultra-modern building that, both inside and out, manages to combine tradition and innovation, form and function in harmony. "With the Breitling Chronométrie complex, we have an extremely high-performance production facility," reads the company documents, "which allows us to maintain control of all operations, from the machining of movement parts to final adjustments. Including the air you breathe. And not in a manner of speaking. Since a watch's performance also depends on the quality of the air in the rooms in which it is housed, Breitling uses a sophisticated system to regulate the humidity and temperature in each room. Thus, in order to prevent the watches from condensation when they are moved to a colder space, the temperature of the embedding rooms is set between 20 and 23 °C, the relative humidity remains constantly below 50% and the air is entirely renewed six times an hour. A filtering system also eliminates all dust that could foul the movements. Technology at the forefront, then? Definitely yes, but also a great deal of attention to the environment, as the company has been committed to sustainability for years, both within the manufacture and by supporting the projects of various organisations.
