Far from being an invention of the twenty first century, technological wearables devices have been a part of our cultural heritage for almost five hundred years. This a precursor of a wrist watch as an earliest known dated watch. It was made in 1530 for a humanist Philipp Melanchthon by an unknown German artisan. It is thought to originate in Augsburg, and currently resigns in the collection of The Walters Museum of Art in Baltimore Maryland. And whats particular remarkable: this beautifully crafted technological marvel is still capable of keeping time.
