How Does a Watch Winder Work?

Automatic watches rely on motion to operate. The user’s motion of the arm creates a forward and back movement of a weighted component in the watch, called a rotor. This movement generates the necessary energy to power the watch by winding the mainspring. Because of gravity, some automatic watches lose power when not worn for a long period of time. A watch winder resolves this issue by providing a similar motion to what a user’s arm would create to power the watch.

What Is a Watch Winder?

A watch winder is an automatic storage unit for a watch. It gently rotates the watch at regular intervals on a plush cushion. A watch winder is a continuous-cycle device. A high-end watch winder consists of both a rotate and rest cycle to mimic the natural wearing of the watch.

There are different sizes of watch winders available. The watch winders can range from a single watch winder to a larger one that stores six or more watches. The more sophisticated models also include spaces for watches to be stored that do not need winding.

How Does a Watch Winder Power an Automatic Watch?

An automatic watch uses a movement mechanism to wind the mainspring. The mechanism is activated when the watch is moved. Movement of the watch signals the mechanism to move rotors to wind the mainspring.

Automatic wristwatch winders use an electric motor to move the watch around, either in a single direction or a combination of both directions. Gravity serves to move the rotors in the watch, and as a result, the mainspring stays wound just like in the case of normal wear.

A watch winder does not charge a battery. It provides the necessary movement to wind a mechanical self-winding watch. This feature means that it is not required for quartz or manually wound watches.

What Do Turns Per Day Mean?

TPD, or turns per day, is a measurement of how many full rotations a winder does in twenty-four hours. An automatic movement has its own winding requirements. Some movements wind in a single direction, some wind in the other direction, and some wind in both.

Automatic watches typically operate in the 650 to 900 TPD range, but owners should always check their watches before making assumptions. Wolf mentions that settings may differ based on the brand, the model, the movement, and the winding direction. Owners should review the manual, movement details, or the official TPD setting guide.

Setting the correct TPD value is of the utmost importance. Having too few rotations is likely to cause the watch to stop, and having too many rotations may cause unnecessary wear on the watch movement.

Can a Watch Winder Overwind a Watch?

No, a watch winder does not overwind a watch because most automatic watches modulate the mainspring to avoid overwinding. However, that doesn't mean watch owners should always select the highest setting.

An optimum programmable winder uses a slow and controlled rotational motion with rest periods. It is designed more to retain the power of the watch and not to keep the motor continuously turning. The correct setting of the TPD and direction ensures an optimal and safe design.

Who Should Use a Watch Winder?

Automatic watch winders work well for collectors who have several mechanical watches and regularly change between them. These watches have features such as alarms, dates, annual calendars, moon phases, and even perpetual calendars.

These settings can take too much time to set once the watch has stopped. Having a watch winder maintains the watch’s power and can be used as an attractive display. For someone who wears one automatic watch every day, a watch winder is not needed.

What Should You Look for When Buying One?

Choose a model with adjustable TPD, multiple rotation directions, quiet operation, and a secure cushion. The cushion should hold the watch firm, without causing the bracelet or strap to dig into the watch.

A quality automatic watch winder should offer rest cycle control. The watch winder's build quality, motor noise, capacity, interior lining, power supply options, and warranty are all important elements when considering the potential purchase. 

A quality, luxury winder should protect and display luxury watches, while a closed watch winder should protect watches from dust.
