Watchmaking importance -----> First Tourbillon by Abraham Louis Breguet

Dear watchaficionado.

Some watchmaking importance: the first Tourbillon finished by Abraham Louis Breguet which he incorporated in a early chronometer timepiece by John Arnold and gifted to his son John Roger in 1808 as an hommage to his father for his work on the development on the Tourbillon but he couldn't finish it as he died in 1799.

Kind regards.
