Winding accessory Double Protective Glass

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 1,200 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 1,200 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.

For your automatic watch to fit into the winder properly, you'll need to choose the right sized watch holder. To choose the most suitable size for your automatic watch, we recommend checking the size guide when making your order.

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.

You can connect to the Masterbox automatic watch winder via Bluetooth using our mobile app. When you turn on your Masterbox watch winder, Bluetooth is automatically activated. To connect as quickly as possible, open the Bluetooth settings on your phone in advance, and then turn on your Masterbox watch winder.

When the Masterbox name appears under your available devices, click on it to connect.
