Ever since the onslaught on time, we humans have always been depended on its course, and after the invention of watches, the dependency increased even more. After all, now we could actually keep track of time. But the saga has not been so simple. There was a time when we used to have old grandfather clocks, which used to announce the time, to the entire house-hold (if not the entire locality!), with its legendary gongs; and today we wear a watch right on our wrists.

When wrist watches first came into the market in the early 20th century, it was a pleasant break from the cumbersome and delicate pocket watches. At first wrist watches used to be mechanically driven, by constantly winding the crown spring, from time to time. However, we have come a long way since then, and now we have been ushered into an era of Quartz watches. These are installed with an electronic oscillator and are regulated by a quartz crystal to keep track of time.

The frequency generated by the crystal oscillator is very precise are far more accurate compared to the old mechanical watches. The quartz watches was first seen in 1970. However, even from that time onward, constant technological progresses have kept altering the size of the mechanisms, making it smaller and smaller.

What the battery means to the watch, is exactly what our heart means to us; the only difference being, the former one is replaceable, once its life is over. The quartz watches are electronic by nature and need a battery as a source of energy, to carry on with the work, that they are destined to do.

The size and type of the battery to be used depends on the make of the watch, and it circuit. There is a huge variety available. However, the one designed by Sony is most preferred by the watch makers, as they have longer life than most contemporary batteries. Sony 315 Watch Battery SR716SW is one of the popular prototypes. What makes it so special is that it does not contain any mercury.
