What ceramic material are watch cases made of?

Advantages of ceramic watches
   1. Ceramics are known for their hardness, especially when compared to steel or other metals. This material is typically three to four times harder than stainless steel. There are no signs of wear even after years of use.
2. Although ceramic watches look heavy, they are lighter than most metals and have a light texture, which is basically similar to aluminum. It is easy to wear on the wrist and comfortable to wear.
3. Because ceramic watches do not contain metal, they will not rust and are more resistant to corrosion. Most people, even those with sensitive skin, can wear a ceramic watch without skin irritation or allergic reactions. Some brands use ceramic in sports and diving watches because it can also withstand the erosion of seawater.
4. Ceramic is an excellent material for black watches. Unlike coated metal watches, ceramic watches are more resistant to fading and abrasion. In addition, the ceramic is not affected by UV rays, which means that the watch's color will not fade even when exposed to sunlight.
Many watch manufacturers use ceramics such as - Rolex, Omega, Rado, IWC, etc.

Disadvantages of Ceramic Watches
1. Although ceramic is scratch-resistant and durable, it is prone to chipping;
2. The processing is difficult, and the process of manufacturing ceramics is very complicated. Heating and cooling require a lot of time, the process control is complicated, and the yield is relatively low. Once formed, ceramics need to be polished, which also adds to the cost, which is one reason why ceramic watches tend to be more expensive than metal watches.
3. High price, as just mentioned, because ceramics are difficult to manufacture, watches made of this material are more expensive compared to traditional metal watches.
