The term originated with mechanical timepieces, whose clockwork movements are made of many moving parts.
The standard movement was designed to have fewer parts than other similar movements, so that it was easier to produce and service, while at the same time maintaining high accuracy and reliability. The basic specification of the Standard wristwatch caliber is a minimum of 17 jewels, 21,600 bph (beats per hour) escapement , a minimum 40-hour ...
