Reading time with Peter Henlein

Peter Henlein, a 16th-century locksmith and clockmaker from Nuremberg, Germany, is considered to be the architect of the first ‘watch’. Devices for reading time, like sundials, obelisks, and hourglasses were used to measure the passage of time since ancient ages. The credit for the first mechanical water clock goes to the Chinese genius Su Song, for which he used the principle of escapement.
