So surprise to find that Graham, and Jeanrichard are much older than PP!
Once again, from watch-wiki.net:
"Graham London (formerly The British Masters S.A. and Les Monts S.A.) is a Swiss watch manufacturer known for restarting iconic British brands, Graham and Arnold & Son.
The company was founded in 1995 as Les Monts S.A. by Eric Loth, Pierre-André Finazzi, and Ernst Thomke, formerly of SMH. They were joined by Max Imgruth, who launched the Swatch brand in the United States, and Jean-Pierre Jaquet.
The idea behind the concept of The British Masters was to recollect the tradition of the great British watchmakers, namely George Graham (1673-1751) and John Arnold (1736-1799). The first collection of "Graham" and "Arnold & Son" was brought on the market in 1998."
