There are three main types of battery that are used to power watches. The most common is the silver oxide battery. They are frequently used in watches because they have a high energy to weight ratio. This means that they should last for a long period of time. Due to the silver content they can be expensive to produce which is why they are not often used for products that take larger batteries.

Lithium batteries are long-life and also relatively expensive. They are used primarily in watches that have lights or other energy draining features.

Solar cells are now becoming a popular and effective way of powering wristwatches. High-tech battery cells are fuelled by the light that reaches them through the watch face. This means that the user will never have to change the battery. Citizen’s Eco-Drive range has set the standard for the practical application of this technology. As an additional ecological bonus the batteries do not contain any of the harmful chemicals found in regular batteries.
