A watch (or the Hour) in a dream indicates the coming of the Hour (Day of Judgment) or a matter that happens suddenly. It may also indicate travel or a change in conditions. Looking at it indicates waiting for relief.

A watch indicates sustenance, debt, or worry. Its stopping indicates the disruption of affairs. Fixing it indicates rectifying a corrupt matter.

A watch is interpreted as glad tidings or a warning. If it is accurate, it indicates the straightness of affairs. If it is broken, it indicates chaos.
