Quick Answer:
A quartz movement watch uses a battery-powered electronic oscillator regulated by a quartz crystal to keep time. Unlike mechanical watches that rely on springs and gears, quartz watches use electrical pulses to drive the movement. They're the most accurate and affordable type of watch available, losing only 15-30 seconds per month compared to mechanical watches that can drift minutes per day.
This guide explains how quartz movements work, their advantages and limitations, and how they compare to mechanical alternatives.
Understanding Quartz Watch Movements
Quartz movements revolutionized the watch industry in the 1970s, making accurate timekeeping accessible to everyone. Before quartz, only expensive mechanical watches offered reliable time. Today, quartz powers everything from $10 digital watches to luxury timepieces costing thousands.
The Basic Principle:
At the heart of every quartz watch sits a tiny quartz crystal—the same mineral found in sand and rocks. When electricity from a battery passes through this crystal, it vibrates at an incredibly precise frequency: 32,768 times per second. These vibrations are so consistent that they serve as a near-perfect timekeeping standard.
The watch's electronic circuit counts these vibrations and converts them into regular one-second pulses. These pulses drive a tiny electric motor (called a stepper motor) that moves the watch hands or updates a digital display.
Why "Quartz"?
Quartz crystals exhibit a property called piezoelectricity. When you apply voltage to quartz, it vibrates. Conversely, when you vibrate quartz, it generates voltage. This two-way property makes quartz perfect for timekeeping—it vibrates consistently when powered and provides feedback to regulate itself.
How Quartz Movements Work: Step-by-Step
Understanding the quartz movement process helps you appreciate why these watches are so accurate and affordable.
The Components
1. Battery (Power Source)
- Typically a silver oxide button cell (SR626SW, CR2016, etc.)
- Lasts 2-5 years depending on features
- Provides 1.5V or 3V of stable power
2. Quartz Crystal Oscillator
- Tiny tuning-fork-shaped crystal
- Cut to precise dimensions
- Vibrates at exactly 32,768 Hz (2^15, a binary-friendly number)
3. Integrated Circuit (IC)
- Counts crystal vibrations
- Divides 32,768 vibrations down to 1 pulse per second
- Controls the stepper motor
4. Stepper Motor
- Miniature electric motor
- Receives one pulse per second
- Moves watch hands in discrete steps
5. Gear Train (Analog Watches)
- Reduces motor movement to appropriate hand speeds
- Hours hand: 1 rotation per 12 hours
- Minutes hand: 1 rotation per 60 minutes
- Seconds hand: 1 rotation per 60 seconds
The Process
Step 1: Battery provides electrical current to the circuit.
Step 2: Circuit applies voltage to the quartz crystal, causing it to vibrate at 32,768 Hz.
Step 3: Circuit counts these vibrations and divides by 32,768, producing exactly one pulse per second.
Step 4: Each pulse triggers the stepper motor to advance the seconds hand one position.
Step 5: The gear train translates this motion to the minutes and hours hands.
This entire process happens continuously, powered by a battery that lasts years without intervention.
Types of Quartz Movements
Not all quartz watches are the same. Different designs serve different purposes.
Analog Quartz
Description: Traditional watch face with hour, minute, and seconds hands.
Characteristics:
- Classic watch appearance
- Stepper motor drives physical hands
- Often includes date complication
- Most common type of quartz watch
Examples:
- Seiko Quartz Dress Watches
- Timex Weekender
- Citizen Eco-Drive (solar-powered quartz)
Best For: Those who prefer traditional watch aesthetics but want quartz accuracy and convenience.
Digital Quartz
Description: LCD or LED display showing time numerically.
Characteristics:
- No mechanical hands
- Can display multiple time zones, alarms, timers
- Lower power consumption (no motor needed)
- Often includes additional functions (backlight, stopwatch, etc.)
Examples:
- Casio F-91W
- Timex Ironman
- Digital dive computers
Best For: Athletes, military, those needing multi-function capabilities.
Meca-Quartz (Hybrid)
Description: Quartz timekeeping with mechanical chronograph complications.
Characteristics:
- Main timekeeping: battery-powered quartz
- Chronograph (stopwatch): mechanical module
- Instant reset and smooth operation of chronograph hands
- Combines quartz accuracy with mechanical chronograph feel
How It Works:
The base movement uses quartz for hours, minutes, seconds. When you activate the chronograph, a mechanical module (powered by springs and gears) drives the stopwatch hands. This gives the satisfying "snap" of chronograph buttons and instant reset that pure quartz chronographs lack.
Examples:
- Seiko VK63 movement (used in many mod watches)
- Citizen Eco-Drive chronographs
- Some Bulova chronographs
Best For: Enthusiasts who want quartz reliability but prefer the tactile feel of mechanical chronographs.
High Accuracy Quartz (HAQ)
Description: Precision-engineered quartz movements with exceptional accuracy.
Characteristics:
- Accuracy: ±5 to ±10 seconds per year (not per month)
- Temperature compensation circuits
- Higher-quality components
- Significantly more expensive than standard quartz
Technology:
HAQ movements use multiple quartz crystals or temperature sensors to compensate for environmental factors that affect timekeeping. They also employ higher-precision ICs and better manufacturing tolerances.
Examples:
- Grand Seiko 9F quartz (±10 sec/year)
- Citizen Chronomaster (±5 sec/year)
- Breitling SuperQuartz (±10 sec/year, COSC-certified)
Best For: Those who demand maximum accuracy and are willing to pay a premium for it.

When to Choose Quartz
Choose quartz if you:
- Prioritize accuracy and reliability
- Want low maintenance (just battery changes)
- Need additional features (alarms, timers, multiple time zones)
- Prefer thinner watches
- Are on a budget ($50-$500 range)
- Want a daily beater watch that you never think about
Real-World Scenario:
You're a nurse, teacher, or office worker who needs to know the exact time without fuss. You don't want to worry about winding, setting, or servicing your watch. Quartz is the obvious choice.
When to Choose Mechanical
Choose mechanical if you:
- Appreciate traditional watchmaking craftsmanship
- Enjoy the ritual of winding or wearing an automatic
- Value heritage and collectibility
- Prefer the smooth sweep of mechanical seconds hands
- Don't mind occasional servicing
- Want a watch that can last generations
Real-World Scenario:
You're a watch enthusiast who appreciates the engineering and artistry of mechanical movements. You're willing to accept slightly less accuracy in exchange for the satisfaction of owning a tiny mechanical machine on your wrist.
Advantages of Quartz Movements
Let's be honest about what quartz does better than mechanical.
1. Superior Accuracy
Standard quartz watches lose 15-30 seconds per month. That's roughly 3-6 minutes per year. High-accuracy quartz (HAQ) models lose less than 10 seconds per year.
Compare this to mechanical watches:
- Standard automatic: ±10-20 seconds per day (up to 10 minutes per month)
- COSC chronometer: ±4-6 seconds per day (up to 2 minutes per month)
For anyone who actually needs to know the correct time, quartz wins decisively.
2. Low Maintenance
Battery replacement every 2-5 years is the only regular maintenance quartz watches need. Cost: $10-$20 at most watch shops.
Mechanical watches require full service (cleaning, oiling, regulation) every 5-7 years. Cost: $150-$400 for standard movements, $500-$1,500+ for complications.
Over 20 years:
- Quartz: 5 battery changes = $50-$100 total
- Mechanical: 3 services = $450-$1,200+ total
3. Affordability
You can buy an excellent quartz watch for $50-$200. For that price in mechanical watches, you're limited to low-end automatics with inconsistent quality.
Quartz movements cost $5-$50 to manufacture. Mechanical movements cost $50-$500+ to produce, even for basic calibers.
4. Durability & Reliability
Fewer moving parts mean less to break. Quartz movements typically have:
- 5-10 moving parts
- Solid-state electronics (no wear)
- No lubrication required (no oil degradation)
Mechanical movements have:
- 100-300+ moving parts
- Require lubrication (degrades over time)
- Sensitive to shocks and magnetic fields
A $50 quartz watch will often outlast a $500 mechanical watch in daily wear.
5. Additional Features
Quartz movements easily incorporate:
- Multiple time zones
- Alarms and timers
- Perpetual calendars
- Backlighting
- Water resistance (fewer openings for moisture)
These features are either impossible or prohibitively expensive in mechanical watches.
Disadvantages of Quartz Movements
Quartz isn't perfect. Here's what you give up.
1. Battery Dependency
You must replace the battery every few years. If you forget, the watch stops. In contrast, automatic mechanical watches wind themselves through wrist motion.
Mitigation: Solar-powered quartz watches (Citizen Eco-Drive, Seiko Solar) eliminate battery changes. They charge from any light source and run for months in darkness.
2. Limited Lifespan
Quartz movements typically last 20-30 years before electronic components fail. At that point, repair is often impossible or uneconomical—you replace the entire movement.
Mechanical movements, with proper service, can last 50-100+ years. Watchmakers can fabricate replacement parts if needed.
3. Lower Collectibility
Most quartz watches don't appreciate in value. Exceptions exist (vintage Seiko quartz, Grand Seiko 9F), but they're rare.
Mechanical watches, especially from prestigious brands, often hold or increase in value. This is partly emotional (craftsmanship appreciation) and partly practical (longevity).
4. Ticking Seconds Hand
Quartz seconds hands "tick" once per second, producing visible jumps. Some find this less elegant than the smooth sweep of mechanical movements (6-10 ticks per second).
High-frequency quartz movements exist (4-16 ticks/sec) but are uncommon.
5. Less Emotional Connection
This is subjective, but many watch enthusiasts feel less attachment to quartz watches. There's no ritual of winding, no visible rotor, no sense of owning a miniature mechanical marvel.
For collectors and enthusiasts, this matters. For everyone else, it's irrelevant.

Caring for Your Quartz Watch
Quartz watches are low-maintenance, but a few simple steps extend their life.
Battery Replacement
When to Replace:
- Seconds hand jumps 2-4 seconds at a time (end-of-life indicator)
- Watch stops
- Digital display dims
Where to Replace:
- Local jewelry store or watch shop: $10-$20
- Brand service center: $20-$40 (includes gasket replacement)
- DIY (if comfortable with tools): $2-$5 for battery
Important: Have gaskets (seals) replaced when changing batteries in water-resistant watches. Old gaskets dry out and allow moisture in.
Water Resistance Maintenance
Even if your watch is rated 100m water resistant, have gaskets checked every 2-3 years. Gasket replacement costs $15-$30 and prevents water damage.
Never:
- Operate crown or buttons underwater
- Expose to hot water (showers, saunas) without 100m+ rating
- Skip gasket replacement during battery changes
Cleaning
- Wipe case and crystal with microfiber cloth weekly
- For metal bracelets: wash with mild soap and soft brush
- For leather straps: wipe with damp cloth, condition annually
Storage
If not wearing for extended periods:
- Remove from direct sunlight (prevents dial fading)
- Store in room temperature (avoid extreme heat/cold)
- Battery will still drain—expect to replace upon next use if stored >2 years
Frequently Asked Questions
Are quartz watches less prestigious than mechanical watches?
Not inherently, but market perception differs. In the luxury watch world ($5,000+), mechanical movements are valued for craftsmanship and heritage. However, Grand Seiko's 9F quartz movements ($2,000-$4,000) are highly respected for their engineering and finishing.
For everyday watches under $1,000, quartz is often the smarter choice. It's more accurate, more reliable, and more practical.
Prestige comes from the brand, materials, and design—not solely the movement type. A $200 Seiko quartz often looks and functions better than a $200 mechanical watch.
How long do quartz watches last?
Electronic lifespan: 20-30 years typically. After this, the integrated circuit or quartz crystal may fail. Replacement is often uneconomical unless it's a high-end watch.
Physical lifespan: Indefinitely if you keep replacing the movement. Quartz movements are cheap ($10-$50), so replacing a dead movement in a quality case is practical.
Battery lifespan: 2-5 years per battery, depending on features. Solar quartz watches eliminate battery replacement.
Can quartz watches be repaired?
Basic servicing (battery, gaskets, crystal replacement) is straightforward and cheap. However, if the electronic circuit fails, repair is usually impossible—you replace the entire movement.
For inexpensive watches ($50-$200), movement replacement makes sense. For luxury quartz watches ($1,000+), manufacturers often have proprietary service programs.
Are expensive quartz watches worth it?
Depends on your priorities.
Not worth it if: You only care about timekeeping. A $50 Casio keeps time as well as a $2,000 Grand Seiko 9F.
Worth it if: You value:
- Exceptional accuracy (HAQ movements ±5-10 sec/year)
- Premium materials (titanium, sapphire, ceramic)
- Craftsmanship and finishing (Grand Seiko finishing rivals mechanical watches)
- Low maintenance with luxury aesthetics
Grand Seiko 9F, for example, offers mechanical-level finishing with quartz accuracy. If you want a luxury daily wearer that never needs servicing, it's excellent value.
Do Seiko mod watches use quartz movements?
Some do. While most Seiko mods use automatic movements (NH35, 6R35), meca-quartz chronographs using the Seiko VK63 movement are popular for custom builds.
The VK63 combines quartz timekeeping accuracy with a mechanical chronograph module, offering the instant reset and smooth operation enthusiasts prefer. These builds typically cost $400-$700 depending on materials.
Custom builders can also create quartz-powered field watches, dive watches, or dress watches for clients who prioritize accuracy and low maintenance over mechanical tradition.
Should I buy solar quartz or regular quartz?
Solar quartz advantages:
- No battery replacements ever (charges from any light)
- Runs for months in darkness after full charge
- Environmentally friendly (no disposable batteries)
- Long-term cost savings
Solar quartz disadvantages:
- Slightly more expensive upfront ($20-$50 premium)
- Capacitor eventually degrades (15-20 years, replaceable)
- Requires occasional light exposure
Recommendation: If you're buying a $200+ quartz watch you plan to keep for 10+ years, solar makes sense. For budget watches under $100, regular quartz is fine.
Popular solar quartz brands: Citizen Eco-Drive, Seiko Solar, Casio Tough Solar.
Which is more accurate: quartz or atomic watches?
Atomic watches are technically quartz movements with radio receivers that sync to atomic clock signals. This makes them the most accurate consumer watches available—essentially perfect timekeeping.
Accuracy:
- Standard quartz: ±15-30 sec/month
- High accuracy quartz (HAQ): ±5-10 sec/year
- Atomic quartz: ±1 second per million years (when synced)
Limitations:
- Atomic watches only work in regions with atomic clock signals (North America, Europe, Japan)
- Require manual adjustment if traveling outside coverage areas
- Slightly bulkier due to radio antenna
Best atomic quartz watches: Casio G-Shock (many models), Citizen Eco-Drive Atomic
Final Thoughts
Quartz movements represent one of the most significant innovations in horology. They democratized accurate timekeeping, making precision watches accessible to everyone regardless of budget.
Key Takeaways:
- Quartz watches use battery-powered electronic oscillators for timekeeping
- They're 10-100x more accurate than mechanical watches
- Low maintenance (battery every 2-5 years)
- Affordable ($10-$500 for excellent examples)
- Less collectible than mechanical, but more practical for daily use
- High accuracy quartz (HAQ) rivals chronometer accuracy at lower cost
Who Should Choose Quartz:
If you want a reliable, accurate, low-maintenance watch for daily wear, quartz is the logical choice. It's perfect for people who view watches as tools rather than collectibles.
Who Should Consider Mechanical:
If you appreciate traditional craftsmanship, enjoy the ritual of winding, and value heritage over precision, mechanical movements offer an emotional connection quartz cannot match.
The Honest Truth:
For 95% of people, quartz watches make more sense. They're more accurate, more reliable, and more affordable. The 5% who prefer mechanical watches do so for emotional and aesthetic reasons—and that's perfectly valid.
Both technologies have their place. Choose based on your priorities: practicality (quartz) or craftsmanship (mechanical).
