Replace one of the pillows in your watch case with this insert so you can store and charge your watch in your watch case.
Everything is friction fit, so you shouldn't have to use any kind of tape or adhesive to keep the charger in place.
Tested with this watch case but I believe most watch case pillows are roughly the same dimensions. All you need to do is make a hole in the case big enough to fit the charging cable through.
