Early spring-driven watches

Portable spring-driven timepieces appeared in southern Germany, France and Italy in the early sixteenth century; Peter Henlein of Nuremberg is traditionally credited, although the historical record is complex. These early watches were worn as pendants or carried, had iron or brass movements with a verge escapement and a foliot or small balance, and used a stackfreed or fusee to equalise spring force. They indicated hours only and were notoriously inaccurate.

From the later sixteenth century watches were made in Blois, Paris, Geneva, London and Augsburg in oval, octagonal, cruciform, skull and other 'form' cases of rock crystal, gilt brass, silver and enamel. They were jewellery and status objects as much as timekeepers.
