I just received my kit and started the video. First my pro tool kit looks different than the kit in the video, which is fine but unnerving for someone doing this the first time. Then the first step is to remove the leather mat that can serve as a work space to protect the watch components. I’m unable to locate this in my kit- testing through every later and nook and cranny, but no leather mat. Does this version of the pro kit not come with a mat? Again unnerving and worrisome for how much I might be missing and how different the experience will be from the video.
