Watches are designed to keep time even when they’re not being worn. However, many people may notice that their watches stop after a certain period of time when not worn. This can be concerning for watch owners who want to ensure that their timepieces are always accurate.
In this article, we’ll explore why watches stop when not worn, how long they can go without being worn, and what to do if your watch stops.
How mechanical and quartz watches work
Mechanical watches operate through the interaction of a mainspring, a series of gears, and a balance wheel. The mainspring is wound by the user and stores energy that is gradually released to drive the gears that power the watch’s hands. The balance wheel regulates the flow of energy to ensure consistent and accurate timekeeping.
In contrast, quartz watches use a battery to power a quartz crystal that vibrates at a precise frequency, which is then translated into timekeeping via a microchip.
Power reserve and winding mechanisms
Mechanical watches require regular winding to keep the mainspring fully charged. Some watches have automatic winding mechanisms that use the motion of the wearer’s wrist to power the watch. Additionally, power reserve indicators display the amount of energy left in the mainspring. Quartz watches typically have a longer battery life and do not require regular winding.
Factors that affect a watch’s accuracy and performance
There are several factors that can affect a watch’s accuracy and performance, including temperature, humidity, magnetic fields, and shock. Temperature changes can cause the metal components of a watch to expand or contract, impacting its accuracy. Humidity can also cause damage to the internal components, while magnetic fields and shock can disrupt the balance wheel and affect timekeeping.
The impact of long periods of disuse on a watch
Long periods of disuse can also have an impact on a watch’s accuracy and performance. The lubricants used in mechanical watches can dry out, causing friction between the components. Additionally, quartz watches can experience battery leakage if left unused for too long.
Best practices for storing and maintaining watches
Proper storage and maintenance can help ensure a watch’s accuracy and longevity. Watches should be stored in a dry, cool place away from direct sunlight and magnetic fields. Regular servicing by a professional watchmaker is also recommended to maintain the watch’s performance and extend its lifespan.
Additionally, regular cleaning and polishing can help keep the watch looking its best.
In conclusion, most mechanical watches will stop running if left unworn for an extended period. This is because the mainspring inside the watch winds down and loses its stored energy. However, modern quartz watches use batteries and will continue running even when not worn. To ensure a mechanical watch continues running, it’s important to wind it regularly or invest in an automatic watch winder.
