This is a dock for charging your Apple Watch. It is designed so that the main curve is slightly off tangent and the charging cylinder is 0.5 mm larger to allow a looser fit. The dock only has a single cable channel that is U-shaped instead of three-quarters round. In addition, there is a 5mm hole in the back so you can easily remove the charger. A version with a deeper cable channel and a 20mm rear hole has also been added based on feedback. The 'Big USB' version fits Apple Watch version 6 cables
