A watch case is the outer housing that protects the inner workings of a watch. It is usually made of metal, such as stainless steel, gold, or titanium, and is designed to be both durable and attractive. It typically includes a bezel, which is a metal trim that surrounds the watch face, and a winding crown, which is a knob used to adjust the time and date. The case often features decorative engravings or other embellishments, which can add a personal touch. The case can also affect the water-resistance of a watch, as some models are designed to be waterproof up to a certain depth.
