Swiss luxury watches and precision instruments

History

Giovanni Panerai opened his first watch shop in Florence, Italy, in 1860, eventually expanding the business into a mechanical workshop under his grandson Guido Panerai.

The company became a supplier to the Royal Italian Navy, producing technical equipment and precision diving instruments, often using Rolex-manufactured movements for its watches. Following a period of civilian market entry in 1993, the company was acquired by the Richemont group in 1997 and repositioned as a luxury brand. Production shifted to Switzerland in 2002, and the company currently operates out of a facility near Neuchâtel.
