Automatic vs. Quartz Watches: Which One Should You Buy?
Posted by LJG Watches on
Every watch is powered by a movement, the engine that keeps the hands turning. Nearly every watch you'll shop for uses one of two kinds: automatic (mechanical) or quartz (battery-powered). Neither is "better." They're built for different priorities. Here's how to choose.
How a quartz watch works
A quartz watch runs on a small battery that sends current through a tiny quartz crystal. The crystal vibrates at a precise, steady frequency, and a circuit turns those vibrations into one tick per second.
- Accuracy: excellent, typically within a few seconds to about 15 seconds per month.
- Maintenance: a battery change every few years, and that's about it.
- Price: usually the most affordable way to get a great-looking watch.
- The tell: the seconds hand jumps once per second.
Quartz is ideal if you want to grab a watch and go without thinking about it. Our Casio Classic Analog Quartz, BERNY Titanium Field Quartz and BERNY Moon Phase Dress Quartz are good examples: set them once and forget them.
How an automatic watch works
An automatic watch has no battery. Inside is a mechanical movement of gears and springs, plus a weighted rotor that spins as your wrist moves and winds the mainspring. As the spring slowly unwinds, it drives the hands.
- Accuracy: good but not perfect. A typical everyday automatic movement may gain or lose several seconds a day.
- Power reserve: most run for roughly 40 hours off the wrist before stopping. Wear it daily, or give the crown a few turns, and it keeps going.
- Maintenance: no batteries, but a service every several years keeps it healthy.
- The tell: the seconds hand sweeps smoothly instead of ticking.
People choose automatics for the craftsmanship. You're wearing a tiny machine that runs on your own movement. Many of our Prestige pieces use well-known movements such as the Miyota 8215, Seiko NH36A and PT5000. Skeleton models like the BERNY Skeleton Automatic let you watch the gears work.
Side-by-side comparison
| Quartz | Automatic | |
|---|---|---|
| Power source | Battery | Your wrist movement |
| Accuracy | Seconds per month | Seconds per day |
| Upkeep | Battery every few years | Wear regularly; occasional service |
| Seconds hand | Ticks | Sweeps |
| Typical price | Lower | Higher |
| Best for | Grab-and-go reliability | Craftsmanship and character |
So which should you buy?
Choose quartz if you want the most accurate, lowest-maintenance watch for the money, or you rotate several watches and don't want to reset them.
Choose automatic if you appreciate mechanical engineering, like the smooth sweep of the seconds hand, and plan to wear the watch often.
Many people end up owning both: a dependable quartz for everyday knocks and an automatic for when they want something special. Browse our Everyday collection for quartz workhorses, or our Prestige collection for automatics.
Quick FAQ
Will an automatic stop if I don't wear it? Yes, usually after a day or two. Just wind it with the crown and reset the time.
Do I need a watch winder? No. It's a convenience, not a requirement.
Is quartz "cheap"? Not at all. Quartz is more accurate than mechanical, and plenty of excellent watches use it.
