Is it permissible to use a wristwatch plated with 18-karat gold, and what are the implications of using it for a year?

The predominant opinion is that it is not permissible for men to use items coated with gold. However, there is no blame upon you for having used the watch throughout the past year, due to your ignorance that it was gold-plated. This is based on the saying of the Messenger of Allah, peace and blessings be upon him: "Indeed, Allah has forgiven for my nation their mistakes, their forgetfulness, and what they are compelled to do."
