Despite the complex construction - which has, for example a very intricate holder for the balance that can be adjusted with three screws - the design of Breguet's chronometers allows for a very efficient production process. The train is not fitted between the main plates but sits underneath the dial, which makes it easily accessible. The escapement can be worked on without touching the rest of the movement - a locking lever stops the movement as soon as the balance mechanism is removed.
