  • Patent number: 5367505
    Abstract: A watch with a dumb alarm has a time drive region which is electrically drivable and an alarm drive region which is drivable by a mechanical drive source. The alarm drive region has an alarm wheel engaging the hour wheel, an eccentric weight rotatably supported in an eccentric position, an alarm lever for urging the hour wheel toward the alarm wheel, the alarm lever having a distal end engageable with an engaging portion on the eccentric weight, an externally operable member for controlling the eccentric weight to start and stop operating, a spiral spring for rotating the eccentric weight, and a wheel train for transmitting drive forces from the spiral spring. When a preset time to be announced comes, the hour wheel engages the alarm wheel to allow the eccentric weight to start operating, and power of the spiral spring is transmitted through the wheel train to the eccentric weight to rotate the eccentric weight to produce vibrations thereof.
