What is the difference between the two types of winding system?

The difference is in the way the watch is wound or how the energy is provided to power the watch:For the manually wound watch: The watch is wound by hand, by turning the crown.For the selfwinding watch: The watch is wound by the movements of the wrist. They cause a rotor mounted under the movement to turn, which will wind the watch. You can also wind a selfwinding watch manually by turning the crown.


What are the characteristics of a mechanical movement and a quartz movement?

A mechanical watch consists of a large number of components in three main elements: the energy source, the going train and the regulatory organ.The quartz watch on the other hand has a battery that provides the energy and an electric motor that transforms the electric impulses into mechanical power.The main advantages of the quartz watch over the mechanical watch are its accuracy and a running time of several years.


A trick to recognise a minute-repeater straight away?

A chronometer is a precise timekeeper with a rating certificate from an official institution Chronometer rating certificate issued by COSC, Switzerland’s official chronometer rating office.


How many parts are there in a mechanical movement ?

A mechanical movement may contain anywhere from 100 to 648 parts depending on the characteristics, functions and complications of the caliber.
