Koda horologe quartz watches use imported high-quality batteries. The normal service life of newly purchased watches is more than two years. Because watches consume a certain amount of time during production, transportation and sales, the specific use time of batteries for different watches may be different. In addition, with the aging of the machine core, the use time of the battery replaced behind the watch may also be shortened. Some Rossini watches have the function of indicating insufficient power. When the second hand of the watch bounces every few seconds, it indicates that the battery is about to run out and needs to be replaced as soon as possible. When the battery is about to run out, please find the maintenance personnel to replace qualified batteries in time, so as to avoid leakage of battery electrolyte and damage the machine center. Please put the discarded batteries in the designated battery recycling site to avoid environmental pollution.
