Watch Movements

The movement is the engine of a watch — the mechanism that measures time and drives the hands. It determines how the watch performs, how much it costs, and how you look after it. This guide explains the three types you will encounter, how each actually works, and how to choose between them.

What a Movement Is

A movement is the mechanism that makes a watch function. Most watch companies buy either the complete movement or its components from specialist manufacturers. A small number are vertically integrated, producing their own movements in-house — these are known as Manufactures.

Watches from a Manufacture are usually more expensive and more sought after, because producing a movement in-house demands a level of engineering capability that few firms possess. For collectors, an in-house movement signals both exclusivity and a particular commitment to the craft.

The Three Movement Types

Mechanical movements, whether manual or automatic, run on gears and springs. Quartz movements run on a battery. Despite quartz being the more accurate technology, collectors consistently favour mechanical watches for the centuries of craftsmanship they represent.

Manual Movements

The manual or hand-wound movement is the oldest type of watch mechanism, originating in the sixteenth century. It requires daily winding to keep running, and it is the movement most associated with traditional, collectible watches.

How a Manual Movement Works

1. Turning the crown winds the mainspring, which stores the energy.
2. The gear train carries that energy to the escapement.
3. The escapement releases it in precisely controlled intervals.
4. The balance wheel uses those intervals to oscillate at a constant rate.
5. The dial train transfers the regulated motion to the hands.
6. The hands advance.

Automatic Movements

An automatic, or self-winding, movement is a mechanical movement introduced in the early twentieth century. A weighted rotor winds the mainspring as your wrist moves, removing the need for daily winding. If the watch is left unworn for long enough it will stop and need winding by hand — though taking it off overnight is not enough to run it down.

How an Automatic Movement Works

1. Wrist motion turns the rotor, which winds the mainspring. The crown can also wind it directly.
2. The gear train transfers the stored energy to the escapement.
3. The escapement regulates that energy into precise intervals.
4. The balance wheel oscillates at a constant rate.
5. After a set number of oscillations, the dial train moves the hands.
6. The hands advance accordingly.

Quartz Movements

A quartz movement is powered by a battery and needs no winding at all. It is the most precise type of movement in general production.

How a Quartz Movement Works

1. Electricity flows from the battery to the quartz crystal through an integrated circuit.
2. The current makes the crystal vibrate 32,768 times per second.
3. Those pulses pass through the integrated circuit to the stepping motor.
4. The motor acts on every 32,768th pulse and drives the dial train.
5. The dial train moves the hands — one step, once per second.

That single step per second is why a quartz watch ticks visibly while a mechanical watch appears to sweep.

Which Movement Should You Choose?

There is no single best answer — it depends on what you value. Manual movements suit those who enjoy the ritual and the connection to traditional watchmaking. Automatics offer mechanical character without the daily obligation. Quartz offers accuracy and minimal upkeep at a lower price.

Cost follows complexity rather than precision. Mechanical movements are more expensive than quartz because of the craftsmanship and the number of hand-finished parts involved, not because they keep better time. They do not.

Common Mistakes to Avoid

• Assuming mechanical means more accurate. It does not. Quartz is measured in seconds per month; mechanical in seconds per day. You pay for craftsmanship, not precision.
• Leaving an automatic idle and expecting it to keep time. Without wrist motion the mainspring runs down, typically within about two days.
• Over-winding a manual movement. Stop at the first firm resistance rather than forcing the crown further.
• Setting the date between roughly 9pm and 3am. On many mechanical movements the date change gears are already engaged during those hours, and turning the date manually then can break teeth.
• Skipping service because the watch still runs. Lubricants degrade long before a movement stops. By the time it visibly fails, parts have usually been wearing against each other for years.
