1 Scope
This standard specifies two methods for determining the battery life of a battery-powered watch and specifies the labelling to be used by the manufacturers or the distributors to inform the users.
According to the available information, either the theoretical battery life or the practical battery life must be calculated using the equations given in this Standard.
