The roots of the EPOS Company date back to 1925. In that year, James Aubert founded the watch company James Aubert SA in the Vallée de Joux, well known as the center of the mechanical watch world. James Aubert was an enthusiastic mechanical watch engineer, who dedicated his life to developing new watch mechanisms. He was a master of his art and spent most of his efforts focusing on technical developments of chronographs and minute repeaters.
In the true watchmakers’ tradition, he handed down his knowledge to his son-in-law, Jean Fillon, who then became the leading watch maker for EPOS for many years. Jean Fillon was the origin of stunning EPOS innovations that have made this brand so unique. In his workshop many of EPOS’ own developments of complications were created, such as a Jumping Hour and a Regulator modification.
