Abstract

The present invention concerns the field of watches and time pieces. There is disclosed a mechanism for a watch (10) configured so that heartbeats act as the trigger that initiates updating of a second unit display. There is also described a mechanism for a watch adapted so that a heartbeat acts as a trigger to increment the time display (21). Furthermore there is disclosed a watch which is associated with a heartbeat sensor (30), the watch being adapted to periodically update a time display in response to heartbeats detected by the sensor, whereby the time display is updated every time a heartbeat is sensed.

Claims

1. A mechanism for a watch configured so that heartbeats act as the trigger that initiates updating of a seconds unit display.

2. A mechanism for a watch adapted so that a heartbeat acts as a trigger to increment the time display.

3. A watch that is associated with a heart beat sensor, the watch being adapted to periodically update a time display in response to heartbeats detected by the sensor, whereby the time display is updated every time a heartbeat is sensed.

4. A watch provided with a display unit comprising indicators of hours, minutes and seconds units, the watch comprising a device for keeping track of time, which device is periodically read by the display unit so that the displayed time corresponds with that maintained by the time tracking device, which watch is associated with a heartbeat sensor for sensing heartbeats of a person, wherein the heartbeat sensor is in data communication with the display unit, and wherein updating of the display is triggered in response to heartbeat signals communicated by the heartbeat sensor.
