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.

A watch winding device includes a motor driving a winding operation, an acoustic measurer of the oscillator of a watch in the winding position, and a controller analysing the signals transmitted by the measurer and comparing them to desired values that can be parameterized to regulate the operation of the motor by starting this motor when the operating amplitude of the oscillator is less than a minimum value, and by stopping this motor when the working amplitude is higher than a maximum value, these acoustic measurers are fixed in a base behind an sensing opening of the acoustic sensor. The device includes an acoustic duct which places a receiving port, located inside a chamber for housing a watch, in communication with a transmitting port movable by the motor facing this sensing opening.

An electronic visible light sensor is employed to detect the presence or lack of sunlight. The simple, digital light/dark data from the sensor is fed to electronic circuits which control security and other devices dependent upon day and night status. These circuits are directed and controlled in turn by associated electronic circuits that gather data which measures the length of the solar night, that is, between dusk and dawn, and by deduction, the length of the day. Given that these time periods vary daily and in a regular fashion, the result will necessarily differ by a few minutes each and every day during the 365 day solar year. The resulting day/night time data is used to estimate, with say, a four to ten minute accuracy, taken against the Universal Coordinated Time System, to establish start/stop times, durations and cycles of security and other devices dependent upon the presence or lack of sunlight relative to UCT designated within the universally accepted twenty-four day. These results are fed to the security control circuitry to define control of data to security and other devices.
