The Watch That Never Needs a Battery: A Love Letter to the Automatic Movement
It winds itself from the motion of your wrist. It has no battery. It contains up to 400 individual components, each one smaller than a grain of rice. And it's been doing the same thing, in essentially the same way, for over 200 years. Welcome to the automatic movement — and welcome to the reason mechanical watches matter.
Let us tell you about a piece of engineering that has, by any rational assessment, been completely unnecessary for decades.
The quartz watch movement, invented in the 1960s and mass-produced from the 1970s, tends to be more accurate than a mechanical movement. It's cheaper to make. It requires almost no maintenance. It loses perhaps one second per day rather than the three to eight seconds a typical mechanical watch might gain or lose across the same period.
By the cold logic of pure function, mechanical watchmaking should have died in 1975.
Instead, something rather wonderful happened.
The Quartz Crisis and Why The Craft Survived
When Japanese manufacturers began flooding the world with affordable, accurate quartz watches in the 1970s and early 1980s, the Swiss watch industry collapsed almost overnight.
Hundreds of companies went under. Employment in the Swiss watchmaking industry fell from ninety thousand to less than thirty thousand in less than a decade. It was a genuine industrial catastrophe.
And yet.
A small number of Swiss manufacturers — and a growing community of watch enthusiasts around the world — refused to abandon the mechanical movement. Not because it was more practical. But because it was more interesting.
Because there is something that a quartz watch, for all its accuracy, simply cannot do: it cannot make you feel anything when you open the case back and look at what's inside.
What an Automatic Movement Actually Is
An automatic — or self-winding — movement is a mechanical movement that winds itself using the natural motion of the wearer's wrist.
At its heart is a component called the rotor: a weighted semicircle that pivots freely around the movement's central axis.
Every time you move your arm — walking to the office, gesturing in conversation, reaching for a cup of tea — the rotor spins. That rotation is transferred, through a series of gears, to the mainspring. The mainspring stores that energy as tension. And it is the controlled release of that tension, regulated by a component called the escapement, that powers the gear train, drives the hands, and makes the watch tick.
No battery. No electronics. Pure mechanical energy, harvested from human movement, converted into the measurement of time.
It is, when you fully understand it, quietly extraordinary.
The Numbers Behind the Magic
A high-quality automatic movement contains somewhere between 130 and 400 individual components, depending on the calibre and its complications.
The most refined of these components — the balance wheel, the pallet fork, the escape wheel — operate at tolerances measured in microns. Many are too small to handle without tweezers.
The balance wheel in a typical watch oscillates six times per second. That's 21,600 beats per hour — or around 518,000 beats per day. Every single one of those oscillations is governed by the tension of the hairspring, adjusted by the regulator, checked against the escapement.
Your watch ticks. That sound — that faint, intimate tick — is the balance wheel doing its work.
It is the sound of physics happening at an almost incomprehensible scale of precision.
People pay thousands of pounds for this. And having understood what it involves, the only
surprising thing is that anyone pays less.
The Movements Inside Our Watches
At Edward Christopher®, we use movements selected for their proven reliability, their service records, and their ability to work beautifully within our custom-designed cases.
The Manta and Manta Revelare are powered by the Sellita SW200 — a Swiss-made automatic movement with a 38-hour power reserve, widely regarded as one of the finest mid-range automatic calibres available.
The SW200 is used by respected watch brands across the price spectrum because it does exactly what an automatic movement should: it runs reliably, winds efficiently, and holds its regulation across a wide range of temperatures and conditions.
It is not a movement that tries to be clever. It is a movement that tries to be excellent. We respect that enormously.
The Ripple is powered by the Miyota 9039 — a Japanese automatic calibre produced by Citizen's movement division.
The 9039 is a slim, smooth, and exceptionally accurate movement: the ideal choice for a dress watch where case thickness and wrist feel matter as much as reliability. With a 42-hour power reserve and a self-winding efficiency that puts some Swiss movements to shame, it is, in our view, one of the best automatic movements available at any price.
Both calibres can be serviced by any qualified watchmaker worldwide. This matters more than most people realise. A watch is only as good as its ability to be cared for across a lifetime of use — and both movements have the global service infrastructure to support exactly that.
Why Wearing an Automatic Changes How You Feel About Time
There is a genuinely different relationship between a person and a mechanical watch compared to any other timekeeping device they own.
Your phone tells the time. Your laptoptells the time. The microwave, bafflingly, tells the time. These are all accurate, convenient, but...entirely devoid of meaning.
Your automatic watch tells the time too. But...it also tells the time because you moved your wrist this morning. Because energy from your body is, right now, stored in a spring inside the case, being released in precisely governed increments to drive a gear train that has been running since you put it on.
There is something almost biological about that relationship. The watch needs you. Not in the way a phone needs a charger — passively, electrically — but in the way a living thing needs movement and attention.
Wear it. Wind it occasionally if it's been sitting still. Open the case back and look inside. The movement will reward your curiosity every single time.
One More Thing
If you want to truly understand why mechanical watchmaking has not merely survived the quartz revolution but flourished in spite of it, do this: hold any automatic watch up to your ear and listen.
Tick. Tick. Tick.
Six times per second. 21,600 times per hour. An endlessly patient, impossibly precise, entirely human act of making time visible.
No battery required.
