How to Identify Watch Movements

A watch movement (also known as a ‘calibre’) is what powers a watch to make its functions operate. This internal mechanism moves the hands and powers any complications such as a chronograph, annual calendar or dual time zone.

During my initial watchmaking workshops I learnt very quickly that there are numerous high end branded watches powered by movements made by third parties. Often the movement powering the watch can be purchased for a fraction of the price of the complete watch. ETA movements being one of the main manufacturers that can be found in a large proportion of watches.

During lessons we would often be tasked with seeking a particular movement to work on as a class and this would often lead to countless hours of research discovering which watches actually contained the specific required movement.

How to Identify Watch Movements FAQ

A watch movement is the mechanism that powers a watch and makes it function. It is also known as a caliber or a module. It consists of various parts that work together to measure and display time, such as the mainspring, the gears, the escapement, the balance wheel, and the dial.

There are three main types of watch movements: mechanical, quartz, and hybrid. Mechanical movements use a wound spring to store energy and release it through a series of gears and levers. Quartz movements use a battery and a quartz crystal to generate electric pulses that regulate a motor. Hybrid movements combine elements of both mechanical and quartz movements, such as kinetic, solar, or smart watches.

One way to help with movement identification in your watch is to look at the back of the case. Some watches have a transparent case back that allows you to see the movement. Others have a solid case back that may have some information engraved on it, such as the brand, the model, or the movement number. You can also search online for your watch model and find out more details about its movement.

One easy way to tell if your watch is mechanical or quartz is to look at the second hand. If the second hand moves smoothly and continuously, it is likely a mechanical watch. If the second hand moves in discrete jumps or ticks, it is likely a quartz watch. However, some quartz watches have a sweeping second hand that mimics a mechanical movement, so this method is not foolproof.

Automatic movement is a type of mechanical movement that does not require manual winding. It uses a rotor or a weight that spins when you move your wrist and winds the mainspring automatically. You can identify an automatic movement by looking for a rotor on the back of the case or by checking if your watch has a power reserve indicator on the dial. You can also test if your watch stops running when you leave it idle for a long time.
