FRUCASE 4+6 Watch Winder for Automatic Watches, New Version, Wooden Box with High-end Velvet Interior and Battery Option

• Why should we use a watch winder?

As a precise mechanical instrument, automatic watch movements are designed to be in constant motion. Leaving a mechanical watch unused in drawer for a long period of time will cause lubricants to clot up in complex and critical areas which will hinder watch movements. This dry up process creates accelerated wear on the movement parts when the watch is occasionally worn thereby affecting accuracy and, in some cases, causing damage to the fine mechanic. In order to "exercise" your automatic watch when not being worn, you would require a watch winder. A well-designed watch winder helps maintain proper lubrication and constant running of your fine timepiece. It also minimizes the resetting or adjusting of the watch when left unworn, a convenience especially when it comes to automatic watches with various complications such as perpetual calendars and moon-phases.

• Can automatic watches be damage by the magnetic motor inside a watch winder?

No, automatic watches and their movements are not affected by the magnetic fields generated by the watch winder motor. This magnetic field is so small that it has no bearing on the watch and its movement. Furthermore, all modern automatic watches are made of non-magnetic material such as titanium, brass, stainless, etc. Consequently, they are non-magnetic and unaffected by close proximity to magnetic fields.

• Why does my watch not work properly even when being wound by the watch winder?

For automatic watches to operate property when using a watch winder, it is important to always ensure that the watch is fully wound prior to placing the watch on the winder for winding. This is because watch winders are programmed to operate most efficiently, with the most regulated results, when the watch is containing at least 50% of power reserve prior to being placed on a winder. This is similar to watch manufacturers recommending you to manually wind daily-worn mechanical watches before wearing it as this gives the mainspring its maximum torque for highest precision
