Automatic vs Quartz vs Solar vs Kinetic: Which Watch Movement Fits Your Life?
共有する
Every watch is powered by one of four kinds of movement. They all tell the time, but they do it in very different ways, with different costs, lifespans and appeal. Here is an honest comparison, from a brand that makes automatic watches but won't pretend quartz has no merit.
Automatic (mechanical, self-winding)
How it works: a spring stores energy, a rotor winds it as you move, and a balance wheel and escapement release it in tiny steps. No battery, no electronics. See how an automatic watch works.
- Accuracy: a few seconds to around ten seconds a day.
- Maintenance: a service every five to seven years.
- Lifespan: generations, if serviced.
- Best for: people who value craft, a smooth sweeping seconds hand and a watch they can pass on.
Quartz (battery)
How it works: a battery makes a tiny quartz crystal vibrate 32,768 times a second. A circuit counts the vibrations and moves the hands once a second.
- Accuracy: excellent, typically within about 15 seconds a month.
- Maintenance: a battery every two to five years, and new gaskets when it is changed.
- Lifespan: long, but electronic parts eventually become hard to replace.
- Best for: grab-and-go accuracy and low cost.
Solar (light-powered quartz)
How it works: a quartz movement whose dial absorbs light and recharges a rechargeable cell. Citizen's Eco-Drive is the best-known example.
- Accuracy: as good as quartz.
- Maintenance: very little. The cell lasts many years.
- Best for: people who never want to think about batteries or winding.
Kinetic (automatic quartz)
How it works: a hybrid. Like an automatic, a rotor turns as you move, but instead of winding a spring it drives a small generator that charges a cell powering a quartz movement. Seiko popularised it.
- Accuracy: quartz level.
- Maintenance: the storage cell eventually needs replacing.
- Best for: people who like the idea of self-winding but want quartz accuracy.
Side by side
- Most accurate: quartz, solar and kinetic.
- Least maintenance: solar.
- Longest lifespan and most repairable: automatic.
- Most character: automatic. You can watch it work, hear it, and wind it.
- Cheapest to buy: quartz.
So which should you choose?
If you want a watch that is simply always right, choose quartz or solar. If you want an object that will still run, be repaired and mean something in fifty years, choose an automatic. That is why we make mechanical watches: our Elemental and Air Force run on the Swiss Sellita SW200-1, and our field watches on the Japanese Miyota 82S5.
