Quartz watches run on a battery and a vibrating crystal, so they are cheaper, more accurate and need almost no care. Automatic watches run on a mainspring wound by your wrist motion, so they cost more, drift by a few seconds a day and need servicing every several years, but many owners prefer them for the craft. Hand-wound watches use a mainspring you wind by turning the crown. Which is best depends on what you want from a watch.
Quartz vs Automatic vs Hand-Wound: Quick Comparison
| Quartz | Automatic | Hand-wound | |
|---|---|---|---|
| Power source | Battery | Mainspring wound by wrist motion | Mainspring wound by hand |
| Typical accuracy | Within about 15 seconds a month for standard quartz | Usually within a few seconds a day | Usually within a few seconds a day |
| Maintenance | Battery change every 2 to 5 years or so | Service every 5 to 10 years | Service every 5 to 10 years |
| Price for a good one | Lowest | Mid to high | Mid to high |
| Needs winding or setting | No | If not worn for a day or two | Daily |
| Thickness | Usually slimmest | Thicker | Often slimmer than an automatic |
How a Quartz Watch Works
A quartz watch passes a small current from a battery through a quartz crystal, which vibrates 32,768 times per second. A circuit counts those vibrations and moves the hands once a second. Because the crystal is so steady, quartz watches are more accurate than any ordinary mechanical watch. Solar and light-powered versions such as Citizen Eco-Drive charge a rechargeable cell, so they avoid battery changes for years.
How an Automatic Watch Works
An automatic movement uses a weighted rotor that spins as you move your wrist and winds the mainspring. The spring drives a gear train and a balance wheel that regulates the time. Automatics store energy, so most keep running for roughly 40 to 80 hours if you take them off. If you leave one for longer, it stops and you set the time and wind it again. Many automatics also let you wind them by hand.
How a Hand-Wound Watch Works
A hand-wound movement has no rotor, so you wind the mainspring by turning the crown, usually once a day. Without a rotor, the movement can be thinner, and many owners enjoy the daily ritual. It is the least convenient type if you rotate several watches or forget to wind.
Quartz Pros and Cons
Quartz watches are accurate, affordable, and usually the toughest against shock because they have fewer moving parts. The downsides are that they lack the mechanical appeal many collectors want. A good quartz watch is still an excellent daily wearer.
Automatic Pros and Cons
Automatics offer mechanical appeal, a sweeping second hand, and no battery. The downsides are lower accuracy, the need to service them eventually, and a higher price for similar build quality. For most people, an automatic is a choice about enjoyment rather than practicality.
Which Should You Buy?
Buy quartz for the lowest cost, best accuracy and least fuss, especially for a rugged daily or a watch you will wear in tough conditions. Buy an automatic if you want a mechanical movement without daily winding. Buy a hand-wound watch if you like the ritual and want a thinner case. If you are shopping on a budget, our best watches under $500 includes both quartz and automatic options.

Quartz vs Automatic: FAQ
Is quartz or automatic better?
Neither is better in every way. Quartz is more accurate and cheaper to own. Automatic offers mechanical craft and no battery.
Do automatic watches need to be wound?
They wind from wrist movement. If you do not wear one for a day or two, it can stop and needs winding and setting.
How long do quartz batteries last?
Often two to five years, depending on the watch and its features. Solar watches can go much longer.
Do automatic watches hold their value?
Most affordable automatics lose value once worn, just like quartz watches. Buy for enjoyment, not as an investment.
Accuracy and service figures are typical ranges and vary by movement and manufacturer.
