POST Pocket watch - Wikipedia

History of pocket watches started in early late 1400s and early 1500s when mechanical engineering reached the state when simple spring devices could be made. By using the invention of mainspring, German inventor Peter Henlein was finally able to create watches that did not require falling weights as the source of their power. This invention gave birth to the first wave of small portable watches, which were in the beginning worn as a pendant on a chain around the neck. Sign-in Sign-in
