The movement is the engine of a watch and the first decision you should make. Quartz watches are powered by a battery and a tuning-fork crystal; automatic (self-winding mechanical) watches are powered by a rotor that winds a spring from the motion of your wrist. Each has genuine strengths — there is no universal "better", only the better choice for how you want to own and wear a watch. Browse both styles across our Rolex, Omega and wider watch collections.
How each movement works
A quartz watch sends electricity through a quartz crystal that vibrates at a precise frequency, stepping the hands on exactly. An automatic watch uses your wrist movement to spin a rotor, tensioning a mainspring that unwinds through a gear train regulated by a balance wheel. The automatic is, in many ways, a tiny mechanical system you can see through an exhibition caseback.
Side-by-side comparison
| Quartz | Automatic | |
|---|---|---|
| Power | Battery (years) | Wrist motion / manual winding |
| Accuracy | Roughly ±15 seconds/month | Roughly ±a few to tens of seconds/day |
| Power reserve | Battery lasts years | ~36–70+ h when off the wrist |
| Maintenance | Battery change when needed | Periodic service every few years |
| Second hand | Steps once per second | Smooth sweeping motion |
| Character | Set-and-forget tool | Horology, craft, ritual |
Why enthusiasts love automatics
An automatic rewards interaction: the feel of winding it, the sweep of the seconds hand, the sound of the movement and the satisfaction of a device running purely on mechanics. Iconic lines such as the Rolex Submariner are automatics for exactly this reason. The trade-off is that you live with them — setting the time after a weekend off the wrist and servicing periodically.
When quartz is the smarter pick
Choose quartz when you want maximum accuracy for almost no effort: grab-and-go daily wear, a beater watch for travel or sport, and a lower purchase price. Quartz is also less sensitive to knocks and needs no servicing beyond an occasional battery.
Accuracy and expectations
Quartz is the clear winner for pure timekeeping precision, yet an automatic that gains or loses a few seconds a day is normal and part of the design. Position at night can nudge the rate slightly, and a freshly serviced movement runs closer to spec. If exactness matters more than craft, quartz wins every time.
Frequently asked questions
Do automatic watches need winding every day?
If worn daily, the rotor keeps them wound; if left unworn past their reserve (often 36–70+ hours) you simply wind or reset them.
Which lasts longer?
With servicing, an automatic can run for decades and become heirloom; a quartz can also last years but relies on electronic parts.
Are quartz watches cheaper because they are worse?
No — they are cheaper to manufacture and superbly accurate; they simply offer a different experience rather than lesser quality.
Can an automatic be my only watch?
Yes, as long as you accept occasional setting and servicing; many owners happily make one automatic their daily piece.
