Quartz and automatic watches can both be excellent everyday choices, but they solve the same problem in very different ways. Quartz watches use an electronic oscillator and battery or another electrical power source, while automatic watches use a mechanical movement whose mainspring is wound by wrist motion and, on many calibres, manual winding.
The better choice is not determined by which technology sounds more premium. It depends on how you wear a watch, how much attention you want to give it, which functions matter to you and what kind of ownership experience you enjoy.
This guide compares the practical tradeoffs first, then uses current Watchdives examples to show how movement choice works in real products. Prices and availability were checked on September 15, 2026; the selected product page remains the source of truth for current stock and specifications.
Quartz vs Automatic Watches at a Glance
| Factor | Quartz | Automatic |
|---|---|---|
| Power | Electrical power, commonly a replaceable battery | Mechanical mainspring wound by rotor motion and, where supported, the crown |
| Accuracy | Generally more accurate than a mechanical watch | Varies by calibre, regulation, position and operating conditions |
| After sitting unused | Usually continues running until its power source is depleted | Stops after the power reserve is exhausted and must be restarted and reset |
| Seconds-hand motion | Varies by movement; many step once per second, while VH31 advances four times per second | Usually appears smoother because the seconds hand advances several times per second |
| Ownership attention | Low day-to-day attention | More interaction with setting, winding and servicing |
| Best reason to choose | Convenience, accuracy and low maintenance | Mechanical character and enjoyment of the movement itself |
1. Accuracy: Quartz Is Usually the Practical Winner
If keeping accurate time with minimal adjustment is the priority, quartz is usually the easier choice. Mechanical accuracy varies from movement to movement, so there is no single daily accuracy figure that applies to every automatic watch.
Quartz movements use an electronic time base and are generally less sensitive to positional variation than a mechanical balance-and-escapement system. That does not mean every quartz watch performs identically, but it does mean you should compare each movement to its own specification rather than assume all watches share one accuracy standard.
2. Grab-and-Go Convenience
A quartz watch is useful if you rotate several watches or leave one unworn for days at a time. If it still has power, it will normally be ready to wear without restarting the movement or resetting the time.
An automatic watch stores a finite amount of energy in its mainspring. Once that reserve is exhausted, the watch stops. When you return to it, you may need to wind or move it, reset the time and, if present, reset the date according to the movement instructions.
If you enjoy that interaction, it can be part of the appeal. If you want to put a watch on and leave immediately, quartz has a clear practical advantage.
3. Seconds-Hand Motion: Not All Quartz Watches Tick the Same Way
The familiar one-step-per-second seconds hand is common in quartz watches, but it is not universal. The TMI VH31, for example, advances its centre seconds hand four times per second. It remains a quartz movement; the smoother visual motion does not make it mechanical.
Meca-quartz chronographs add another variation. In the Seiko VK63 used by the Watchdives WD1863, the chronograph system provides a sweeping central chronograph seconds hand and an instant snap-back reset while the watch retains quartz-powered timekeeping. See our WD1860 vs WD1863 comparison for a closer look at two current Watchdives VK63 chronographs.
If seconds-hand motion matters to you, check the exact movement instead of shopping only by the broad label “quartz.”
4. Battery Power vs a Mechanical Mainspring
Most quartz watches eventually need a battery replacement or other power-source service. Battery life depends on the movement and how the watch is used.
An automatic watch does not use a conventional quartz battery to power its timekeeping. Wrist motion turns a rotor that winds the mainspring, and many automatic movements also support manual winding. The correct winding method depends on the calibre, so follow the instructions for the specific watch.
Neither system is maintenance-free. The maintenance is simply different.
5. Maintenance and Servicing
Quartz ownership is generally simpler because there are fewer mechanical timekeeping parts to regulate and service. Battery replacement, seals, water-resistance checks and other case-related maintenance may still be necessary.
Automatic movements contain a mechanical gear train, escapement, lubricants and other moving parts. Service needs depend on the movement, use, environment and manufacturer guidance. Avoid universal claims such as “every automatic must be serviced every three years”; use the instructions for the specific calibre and have the watch assessed if its performance changes substantially.
Water resistance is also a property of the complete watch, not the movement. Gaskets, crown, crystal, case back, assembly and testing matter whether the watch is quartz or automatic.
6. Functions and Complications
Movement type does not determine whether a watch can be simple or feature-rich. Quartz watches can offer date displays, chronographs, GMT functions and other complications. Mechanical watches can do the same, but additional mechanical complexity may affect thickness, price and servicing.
Choose the function you actually use. A clean three-hand VH31 watch can be a better fit than an automatic GMT if you never track a second time zone; an automatic diver may be more satisfying if the movement itself is part of why you are buying the watch.
7. Price and Value: Automatic Does Not Automatically Mean Better
Movement cost is only one part of a watch. Case finishing, crystal, bracelet, clasp, dial, lume, water resistance and quality control all consume the product budget.
Quartz can allow a manufacturer to put more of a given price into other components. Automatic watches can offer the mechanical experience some buyers value enough to pay for. The useful comparison is the complete watch, not a rule that one movement type is inherently more premium.
8. Durability and Water Use Depend on the Whole Watch
A quartz movement does not automatically make a watch more rugged, and an automatic movement does not automatically make it suitable for diving. Check the complete specification and the manufacturer's guidance for the exact model.
For example, current Watchdives products include quartz and automatic watches with substantial water-resistance ratings. Their water capability comes from the complete construction and testing, not simply the movement category.
9. Ownership Feel: Convenience vs Mechanical Interest
For some buyers, a watch is mainly a reliable object that should tell the time with minimal attention. Quartz is well suited to that goal.
Other buyers enjoy seeing a mechanical movement through an exhibition case back, feeling the rotor, winding the crown and knowing that the watch is powered by a spring and gear train. That experience is difficult to reduce to a specification and is one of the strongest reasons to choose automatic.
This is a preference, not a quality ranking.
10. Think About How Often You Will Actually Wear It
If you wear one watch almost every day, an automatic movement can remain powered through normal wrist motion when the movement and your activity provide enough winding. If you rotate through a large collection, quartz can be easier because a watch can remain ready even after sitting unused.
Also consider travel, work routines and whether you enjoy resetting a stopped watch. The best movement is often the one that creates the least friction in your real routine—or the kind of interaction you deliberately want.

Frequently Asked Questions
Are quartz watches more accurate than automatic watches?
In general, yes. Quartz timekeeping is usually more accurate and less affected by position than a conventional mechanical watch. Compare exact movement specifications rather than assuming one number applies to every model.
Does an automatic watch need a battery?
A conventional automatic mechanical movement does not use a quartz battery to power timekeeping. It stores energy in a mainspring that is wound by the rotor and, on many calibres, manual winding.
Will an automatic watch stop if I do not wear it?
Yes, after its stored power reserve is exhausted. The amount of reserve varies by movement. Restart and set it according to the model instructions.
Is an automatic watch always better than quartz?
No. Automatic and quartz watches optimize for different things. Quartz is usually stronger for convenience and practical accuracy; automatic is attractive to buyers who value the mechanical movement and ownership experience.
Is the VH31 an automatic movement?
No. VH31 is a quartz movement. Its centre seconds hand advances four times per second, which creates a smoother appearance than a conventional one-step-per-second quartz seconds hand.
Can a quartz watch be a capable dive watch?
Yes, if the complete watch is designed and tested for the intended water use. Movement type alone does not determine water resistance or dive suitability.
Final Verdict: Quartz or Automatic?
Choose quartz if you value accuracy, convenience and a watch that requires very little attention before you put it on. Choose automatic if the mechanical movement and the interaction that comes with it are part of why you enjoy watches.
If you are undecided, start with your routine rather than the movement label. Ask whether you want a watch that simply stays ready, or whether winding, setting and living with a mechanical movement adds something you would enjoy.
There is no universal winner. The better watch is the one whose movement, dimensions, functions and complete construction match how you actually plan to wear it.
