A method for providing information about a mechanical wristwatch, including the following steps, 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 the owner of the wristwatch, based at least on the times and durations of availability of the external energy, when or after the harvested energy quantity reaches a threshold, the 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 the transmission unit.

A timepiece reduces power consumption while maintaining required precision. The timepiece has a frequency divider that frequency divides an oscillation signal and outputs a reference signal; nonvolatile memory that stores information related to a temperature characteristic of the oscillation frequency of the crystal oscillator; multiple registers; a temperature measuring circuit; an evaluation circuit; and a temperature compensation circuit. The temperature compensation circuit reads the information from one of the registers and corrects the reference signal based on the read information and the temperature measurement information when the evaluation circuit determines the information stored in the multiple registers is the same; and when the evaluation circuit determines the information stored in the multiple registers is different, reads the information from the nonvolatile memory, stores the read information in the multiple registers, and corrects the reference signal based on the read information and the temperature measurement information.

An adjustment method of an atmos clock and a detection system performing the adjustment method are provided. The adjustment method includes detecting a magnetic field around a balance wheel of the atmos clock via a magnetic sensor, generating a measured signal, receiving the measured signal via a processing unit, and performing a clamping process on the measured signal. A clamping value is subtracted from the measured signal to generate a clamped signal. A zero value line crosses a waveform of the clamped signal to form a zero crossing point in each of the periods of swing motion of the balance wheel. The adjustment method further includes retrieving a time of the zero crossing point, calculating a time difference between the zero crossing points of two adjacent periods, calculating a length of the period according to the calculated time difference, and outputting the calculated length to an output device.
