Invention of Watches

The pioneer of Watches may be the portable spring driven clocks, that appeared first in 15th century in Europe. Portable time machine were made possible by the invention of the mainspring. Although some sources erroneously credit Nuremberg clockmaker Peter Henlein with inventing the mainspring around 1511, many references to 'clocks without weights' and two surviving examples show that spring powered clocks appeared in the 15th century.
