Case - Watch cases are available in various shapes, materials and sizes. They can either be made from one piece or composed of top part, middle part and back part. The case of a watch is both a decorative element as well as protection against external factors such as water and dust. The back of a watch is called the case back. A sapphire crystal back called a 'view back' or 'transparent back', is often used to provide a view of the movement.

Complication -Complications are the additional functions in watches that go beyond the function of telling the time with hour, minute and second hands, and offers the wearers additional benefits. Small complications are, for example, date or a second time zone. Some examples of large complications are chronographs, perpetual calendar, repetition or the beautiful moon phases.
