A method for controlling an electronic watch that includes a first pointing hand, a first motor configured to move the first pointing hand, a second pointing hand, a second motor configured to move the second pointing hand, and a pressure sensor configured to measure a pressure, the method including, when start of diving is detected based on a pressure measured by the pressure sensor, controlling the first motor and the second motor, and indicating with the first pointing hand and the second pointing hand a water depth based on the pressure and a diving time period.

A manual tooth brush having a timer function. The tooth brush has a body that defines a cavity therein and in which a timer is located. The brush uses an inversion switch instead of an accelerometer to activate the timer. The inversion switch, or tilt switch, may be a mercury type tilt switch or a ball type tilt switch. When the tooth brush is tilted such that the head is below the brush body, the tilt switch is activated and the switch in turn activates the microprocessor. Activating the tilt switch also starts the timer that is linked to the microprocessor. Because the microprocessor is only activated when the tooth brush is tilted, the battery life of the tooth brush is extended. The brush timer is programed to run for about 2 minutes. The tooth brush vibrates or makes a sound every 30 seconds. The timer deactivates after 2.5 minutes.

The invention relates to a method for detecting and calculating the duration of a jump effected by an individual, comprising the following steps: Detection of a moment associated with a landing following the jump, this step comprising a sub-step of detecting an acceleration peak of an amplitude greater than a first threshold amplitude, within the acceleration measurements provided by a three-axis accelerometer, on board a watch worn on the wrist of the individual. Detection of a jump phase, by detection, in a temporal window finishing at the moment of landing, of a succession of acceleration measurements between 0 g and 0.5 g during a duration greater than a first threshold duration.

A time display device, including: an indication display unit which displays a content according to an indicating operation, and a processor, wherein in a case where a remaining time with respect to a reference set time of an elapsed time from a measuring start timing is greater than a predetermined reference remaining time, the processor makes the indication display unit display a ratio of the remaining time with respect to the reference set time, and in a case where the remaining time is equal to or less than the predetermined reference remaining time, the processor makes the indication display unit display the remaining time.
