Method for providing information about a mechanical wristwatch

A method for providing information about a mechanical wristwatch, comprising the following step, performed by the wristwatch:

• harvesting an intermittently available external energy
• storing the harvested energy
• at the end of a predefined period of time, generating an analysis report on an activity of an owner of the wristwatch, based at least on times and durations of availability of the external energy
• when or after harvested energy quantity reaches a threshold, said threshold being on or above an energy level required to power a transmission unit of the wristwatch, wirelessly transmitting the analysis report to a distant reader with said transmission unit
• the method further comprising the following steps, performed by the wristwatch:
• detecting a malfunction of the wristwatch
• generating an alarm message representative of the detected malfunction
• when or after the harvested energy quantity reaches the threshold, wirelessly transmitting the alarm message to a data processing device with said transmission unit.

• the method further comprising the following steps, performed by the wristwatch:
• detecting an electromagnetic radiation beam
• retrieving a diagnosis request embedded in said beam
• generating a diagnostic report representative of an operating condition of the wristwatch
• when or after the harvested energy quantity reaches the threshold, wirelessly transmitting the diagnostic report to a data processing device with said transmission unit.
