Irradiation is a process used to improve the appearance of a watch. It is done by exposing the watch to a controlled amount of radiation, which causes a chemical reaction in the metal and causes it to change color. Irradiation is an effective way to give a watch a unique look and make it stand out from the rest. It can also be used to restore older watches to their original color. Irradiation is a safe and efficient way to alter the look of a watch without causing any damage.
