To provide a measure mechanism having excellent measure accuracy and assembled accurately.

This measure mechanism used in an analog cock has a contact point released to come into contact, a hour measure mechanism for releasing the contact point once in twelve hours corresponding to the measure time, and a minute measure mechanism for releasing the contact point once in one hour corresponding to the measure time. The time measure mechanism and the minute measure mechanism are assembled by a tool, and when they are assembled by the tool, the hour measure mechanism is set to the state after the contact point is released, and the minute measure mechanism is set to the state before the contact point is released.
