Case middle is an important part of a watch. It is the section between the bezel and the case back, which makes up the main body of the watch. It is usually made of metal, such as stainless steel or gold, and holds the watch movement inside. It also often features engravings or details that distinguish the watch model. A case middle can be round, tonneau, rectangular, or any other shape, which is usually determined by the design of the watch.
