History of watches

Watches evolved from portable spring driven clocks, which first within the 15th century. Portable timepieces were made possible by the invention of the mainspring. Although some sources erroneously credit Nuremberg clockmaker Peter Henlein (or Henle or Hele) with inventing the mainspring around 1511, numerous references to 'clocks without weights' and two surviving examples show that spring powered clocks appeared within the 15th century. Henlein is also often credited with constructing the first pocketwatches, mostly due to a passage by Johann Cochlaus in 1511.

Peter Hele, nonetheless a young man, fashions works which even probably the most learned mathematicians admire. He shapes many-wheeled clocks out of little bits of iron, which run and chime the hours with out weights for forty hours, whether or not carried at the breast or inside a handbag

The very first timepieces to be worn, made in 16th century Europe, were transitional in size in between clocks and watches.

They had only an hour hand. The face was not covered with glass, but generally had a hinged brass cover, frequently decoratively pierced with grillwork so the time might be read with out opening.
