Peter Henlein Totally Explained

Everything about Peter Henlein totally explained

Peter Henlein (or Henle or Hele) (1479/1480 – August 1542), a locksmith from Nuremberg, is considered the inventor of the portable watch. His small, drum-shaped Taschenuhr, a portable watch which he invented and made during his asylum from 1504 to 1508, could run for forty hours before it needed rewinding.
Although many sources erroneously credit Henlein with the invention of the mainspring, descriptions and two surviving examples show that spring driven clocks existed by the early 1400s.
