HOW LONG DOES A WATCH BATTERY LAST?
Aside from fancy colored diamonds, the most beautiful color for a diamond is no color at all.
The diamond color scale ranges from D colorless to Z – yellow. Fancy colored diamonds are rated Z and higher. Most Blair's diamonds are graded near colorless.
The life span of a watch battery depends on the age and quality of the watch, its functions, and how often those functions are used.
In most cases, a battery in a brand new quartz watch with basic time and date functionality may last up to four years. As the watch ages, the mechanism wears and drains more power (the reason why factory-installed batteries last longer). Typically replacement batteries last between one to two years. It is possible for a battery to last longer, but we recommend replacing your battery every year, which will avoid potential leakage.
Watches with functions like lights, alarms, and chronographs drain more power, and the more these functions are put into play, the faster the battery will drain. Due to the high power consumption of such functions, some watches may also be equipped with more than one battery.
