In 1875, Jules-Louis Audemars and Edward-Auguste Piguet joined forces to produce watches with complex mechanisms. Based in La Brassus in the heart of Vallée de Joux in the Swiss Jura region, Audemars Piguet has been creating and marketing under its own name a range of Haute Horlogerie watches.
Through World War I and the Great Depression the company managed to develop and despite the harsh economic situation at that time, mainly due to the production of ultra thin and ladies wristwatches. However, despite their survival through this difficult period, production was severely hit. In 1932, they produced only 2 watches compared to nearly 2000 in 1920, resulting in the workforce being reduced.
Today, the company, along with Patek Philippe and Vacheron Constantin, is sometimes claimed to be one of the "big three" Swiss watchmakers. Every timepiece manufactured in-house is still made using the old-fashioned hand-made technique. Currently you can find many of these beautiful Audemars Piguet timepieces on Chrono24.
In my opinion, when this company was founded in 1875, much of the craftsmanship included hand-cranked lathes to turn the and create many of the components inside the timepiece. Audemars Piguet has maintained that same craftsmanship on today's models. Piguet are also know to be some of the most complex and sophisticated mechanisms in the timepiece world. Their mindset to create a limited number of pieces is, they see hand building these more of an art form than anything. The artisans assemble and disassemble each pieces three times before completing the assembly and shipping it off.
