How Does a Kinetic Watch Work?


What is a kinetic watch? A kinetic watch, also known as an automatic quartz watch, combines a self-winding rotor mechanism to generate electricity with a piezoelectric quartz crystal as its timing element.

This type of watch is hailed for its precision and energy saving qualities, factors that have contributed to its sharp rise in popularity. So how does a kinetic watch work? This article will provide the answer to that question plus more.

How Does a Kinetic Watch Work?

Kinetic energy is the energy produced through motion. This type of energy, created by the body’s movement is what powers kinetic watches. Motion like swinging your arms while walking, turning the steering wheel while driving, or simple everyday movements cause the oscillating weights within the watch to rotate.

The rotating pendulum is attached to a large gear which meshes with a small pinion. When you move, the pendulum turns and spins the pinion at a high speed (up to 100,000 rpm). This is coupled to a small electrical generator which charges a storage device (a capacitor or a rechargeable battery). The energy stored in the capacitor discharges slowly over time. Depending on the watch model, a full charge can last anywhere from two weeks to six months.

Are Kinetic Watches Durable?

You may be hesitant to buy a kinetic watch especially if you’re unfamiliar with how it works. But you should know that kinetic watches are just as durable as any other type of watch. The capacitor can be charged and discharged thousands of times. Although a recalibration of the capacitor every 10 years or so is necessary to keep your watch in top condition, the capacitor doesn’t wear out.

Storing Energy

A fully-charged kinetic watch can store energy for as long as six months without requiring a recharge. The main capacitor stores the energy, keeping track of the correct time. Typically, the watch will “go to sleep” after 24 hours of inactivity. When it is reactivated with motion, the time is reset based on the capacitor’s calculations. Many kinetic watches have indicators that let the wearer know how much charge is being held in the timepiece.

Maintenance

Kinetic watches usually require maintenance every seven years or so. The battery doesn’t need to be replaced, but the watch might need a new main capacitor to store energy and keep time.

History of the Kinetic Watch

Japanese company Seiko unveiled the “kinetic watch” at the Basel Fair trade show in 1986 under the name AGM. In January 1988, the first such watch was released in Germany. April of the same year, the watch was released in Japan (under the name Auto-Quartz).
