Frequently asked questions

How does the power supply work in SwissKubik automatic watch winders?

The power supply for your SwissKubik automatic watch winder will depend on the model you own.

  • Startbox: This winder runs exclusively on batteries (2 C 1.5 volt alkaline batteries – —we recommend using Duracell Procell batteries for their quality.)
  • Masterbox: Offering greater power versatility, this winder runs either on mains power or batteries (2 C 1.5 volt alkaline batteries – —as with the Startbox, we recommend using Duracell Procell batteries, but others brands also work). The Masterbox demonstrates built-in intelligence by automatically detecting a mains power source: when plugged in, it automatically switches to mains power, preserving its battery life. Similarly, as soon as the watch winder is unplugged from the mains, it automatically resumes battery operation for uninterrupted use.
    Please note that the USB-C port is a simple power supply used to plug your watch winder into the mains; it cannot be used to recharge batteries. It can also be used to programme your winder via our Mac/Windows app.

Whether you opt for the Startbox or Masterbox automatic watch winder, we recommend that you do not use rechargeable batteries.

What’s the difference between the Startbox and Masterbox automatic watch winders?

While both are designed to protect your timepiece and keep it on time, the Masterbox and Startbox automatic watch winders differ in their design and functionality:

  • Startbox: Measuring 11 x 11 x 11 cm, this perfect cube stands out for its ease of use, operating as soon as it is switched on. With a rotation cycle of 1,600 revolutions per day, the Startbox winder is suitable for most automatic watches.
  • Masterbox: With advanced features like Bluetooth connectivity, this winder allows you to customise rotation cycles according to your desired use via our app (with a standard cycle of 1,600 revolutions per day). With each winder measuring 10 x 10 x 10 cm, the Masterbox is available in a wide range of materials, and can fit 1 to 12 watches depending on the model.
    Completely transportable, both the Startbox and Masterbox watch winders operate on batteries, meaning you can store yours wherever you want – —even in a safe.

How do automatic watches work?

An automatic watch operates on kinetic energy generated by the wearer's wrist movements, which gets stored in the mainspring. For more details, see our article on how automatic watches work.

The art of winding
Preserving your automatic watch

Self-winding mechanical watches work via a complex mechanism using the kinetic energy generated by the wearer’s wrist movements. As such, for this type of watch to keep telling the time accurately and steadily, it needs to be worn regularly. By reproducing natural wrist movements, our watch winders regularly supply energy to the balance wheel which controls the gear speed, maintaining the precision of your watch when it is not being worn.

While most automatic watches can be wound by hand with the crown, a winder helps avoid any potential handling errors that can arise with screw down crowns, for example. Our winders guarantee confidence and peace of mind for every watch enthusiast.
