  • Abstract
    A watch that does not require battery replacement has been developed and launched on the market. There are two types of such watch: one that uses arm movement to generate electricity, and the other a mechanical watch run by a spring with quartz accuracy. It is not easy to get batteries in some parts of the world, making such watches very useful. These watches are also more convenient because there is no need to replace the battery. For the eco-conscious, these watches avoid the use of natural resources and the problem of treating dead batteries. They improve resource productivity greatly with less usage of resources and increased customer convenience
