Audemars created complicated watch movements for different manufacturers to then finish and fit into their own cases. Piguet performed the final regulation. After they started working together in 1875, they continued this split function in different ways. Audemars oversaw the production and technical aspects of the watches while Piguet focused his time on sales and management. The name Audemars Piguet & Cie was first used in 1881. In 1892, the brand created the first-minute repeater wristwatch. By 1899 the first Grand Complication pocket watch was released by the pair, featuring a minute repeater, alarm, perpetual calendar, deadbeat seconds, chronograph, and split-seconds hand. Audemars and Piguet both tragically passed away in 1918 and 1919, but the company continued forward and saw even more success. Continuing through to today, the brand was continued on by the next generation of Audemars and Piguet, this time sons Paul Louis Audemars and Paul Edward Piguet. During the early-mid 1900s, the manufacturer continued to push for innovation within the watch community. The thinnest pocket watch caliber was released by the brand in 1925, while the first skeletonized pocket watch was released in 1934. In 1946, the brand launched the world’s thinnest wristwatch.
