To obtain a wrist watch which can tell a set time only to a user by setting a time to be told freely and actuating a vibration upon reaching a set time so that the vibration is sensed by the user on the skin.

A time to be told is set freely by a time setting means 3 and when the set time is reached, an oscillation means 2 actuates a vibration through reciprocation or eccentric rotation of a weight 7 or rotation of an eccentric plate. A user of wrist watch can sense the vibration on the skin to know the time. A vibration stopping means 4 can stop the vibration automatically after a specified time using an electronic circuit or the vibration can be stopped manually using a push button type switch, or the like.
