The reasons why Omega Haima ceramic dial cracked are as follows.
1. Sudden impact or impact: Although ceramic materials have high hardness, they are fragile. If the dial is suddenly hit or hit, it may cause cracking.
2. Temperature change: If the dial is affected by temperature change for a long time, it may also cause the ceramic dial to crack. In particular, sudden temperature changes, such as from a high temperature environment to a low temperature environment, or vice versa, may cause the ceramic dial to break.
3. Long-term use: Although the ceramic dial has high hardness and wear resistance, it will also have microcracks after a long time. If it is used for a long time, it may lead to the gradual expansion of these micro-cracks and eventually lead to the cracking of the dial.
