1510 - Small wearable spring-driven clock

The first worn watch was built in 1510 by Peter Henlein (Henle, Hele) of Nuremberg. He was a watchmaker, but also a locksmith, who produced boxes locks. All metalworking profession were associated in one craft guild.

The use of a spiral spring for winding (driving of the watch) was a critical for the construction of a worn watch (wearable clock). Flat springs were used for the construction of box locks for many years before the invention of the worn watch. This small spiral spring was used by Peter Henlein to build his primitive basic watch.

Peter Henlein is considered to be the precursor of modern watches. He regularly produced pocket watches since 1524.
