A TPK file is a watchface design build created by Gear Watch Designer, an application used by developers to generate faces for Samsung watches such as Gear S, Gear S2, Gear S3, and Gear Fit2. It contains a build of a .GWD watchface design project which includes the background, index, images, animation, and watch hands. TPK files are designed to be uploaded to the Gear store for distribution.

You can create a TPK file from a GWD project. Select Project from the menu then click Build. Gear Watch Designer allows you to design the watchface. You can specify the dimensions, placement, angle, font type and size, language, and time format of the watchface. Once you are finished designing your GWD watchface you can build it as the TPK file then upload it to the Gear store.
