wristwatch
Quick Summary
A wristwatch is a small watch worn on the wrist, typically attached by a bracelet or strap. The first wristwatches appeared around 1896. Prior to wristwatches, portable timepieces, known as watches, were carried in pockets or worn around the neck. These early watches, dating back to the 1500s, were often driven by a mainspring and had only an hour hand. The development of the balance spring and later the lever escapement significantly improved their accuracy. Modern wristwatches can be mechanical, powered by a mainspring, or electronic, utilizing batteries and integrated circuits.12
