The movement is the watch soul and ensure the correct work during the time. Term “Movement” is taken from the main task of the mechanism: moving the watch hands. The need of time measuring had been always inside human being, who exploited the earth orbit and sun movement as first watch of the history. In this way, sundials born, real first timepiece. During our history, also the time study continued to develop and grow up, to its apex in 1810, when Mr. Breguet built the first mechanical wrist watch.
WHAT ARE THE MOVEMENTS USED IN OUR WATCHES?
Lazzarini use all the available technologies for the manufacturing of their timepieces. Available movements are different for the supplying system, which is different for anyone of them. Most of modern movements work with a quartz crystal, powered by a very little battery through an electronic circuit. Even with this electronic development, love for traditional mechanical movements is not vanished. Also nowadays, mechanical automatic and manual watch movements are available and appreciated by watch passionates and collectors.
HOW DOES A QUARTZ MOVEMENT WORKS?
Quartz movements use a piezoelectric crystal to move the internal gears, which will indicate the time through the hands on the dial. Battery electric charge is wired by an electric circuit to the quartz crystal, which, thanks to its physical properties, will vibe to a steady frequency. These vibrations will ensure the correct movement of the hands.
HOW DOES A MECHANICAL MOVEMENT WORK?
Mechanical watch is inspired by the initial ideas of Mr. Breguet with more modern developments. There are 3 main parts: Charge, gears and balance. Charging part is formed by a belt spring, coiled to a shafts thanks to manual charging (or automatic). The force, initially potential, becomes kinetic through the gear system inside the movement. The kinetic force is carried to the balance system. The balance wheel, together with other components, transform the force in swings, that manage the force distribution through the gear system. This action assure a correct management of the spring force and a consequent accurate time measuring, together with traditional feature.
WHAT IS AN AUTOMATIC MOVEMENT?
For a manual mechanical watch, the watch owner must charge the main spring manually, while for automatic system, the charging mechanism is quite different. Base concept is the same (Charge, gears and balance), but charging of the main spring is carried out by an oscillating rotor, placed (usually) on the back of the movement. This system is directly connected to the charging gear system and assure the correct mainspring charging thanks to owner’s arm movement. The rotor, thanks to a bearings system, will charge the mainspring continuously until discharging.
