Automatic vs Quartz Watches: Which Should You Buy?

The movement is the engine of a watch. It decides how the watch keeps time, how often it needs attention and even how the seconds hand moves. The two you will meet most often are quartz and automatic.

How a quartz watch works

A quartz watch runs on a battery. The battery sends current through a tiny quartz crystal that vibrates at a very stable frequency — 32,768 times per second in most watches. A circuit counts those vibrations and drives the hands forward, usually in one-second steps.

Why people choose quartz:

• Accuracy. A typical quartz watch is accurate to within a few seconds per week, far better than most mechanical watches.
• Low maintenance. Apart from a battery change every few years, there is little to do.
• Value and variety. Quartz movements are inexpensive, so the budget goes into design, materials and features like chronographs.
• Grab-and-go. It keeps running even if you leave it in a drawer for weeks.

Solar quartz watches work the same way but recharge from light, so battery changes are rare.

How an automatic watch works

An automatic (self-winding) watch is mechanical. It is powered by a coiled mainspring, and a weighted rotor inside the case spins as your wrist moves, winding that spring. A balance wheel releases the energy in precise, even beats.

Why people choose automatic:

• Craftsmanship. Hundreds of tiny parts work together without a battery — many owners love seeing them through an exhibition case back.
• The sweeping seconds hand. The hand glides rather than ticks.
• Longevity. A well-maintained mechanical watch can last for generations.

What to keep in mind:

• Accuracy varies. Mechanical watches can gain or lose several seconds a day; certified chronometers are held to tighter limits.
• Power reserve. If you don't wear it for a day or two (depending on the model's power reserve), it will stop and need resetting.
• Servicing. Mechanical movements benefit from periodic servicing — follow the manufacturer's recommended interval.

Which should you choose?

Choose quartz if you want a dependable, accurate watch you never have to think about. Choose automatic if you value traditional watchmaking and enjoy wearing your watch regularly.
