Why Are Mechanical Watches So Expensive Compared To Quartz Accuracy Explained

At first glance, it doesn’t make sense. A $200 quartz watch from a department store keeps better time than a $10,000 mechanical masterpiece. It gains or loses less than ten seconds per month, while its high-end counterpart might drift by several seconds each day. So why do people spend life savings on mechanical watches when quartz movements offer superior precision at a fraction of the price?

The answer lies not in pure functionality but in philosophy, artistry, and heritage. Mechanical watches are not just tools for telling time—they are miniature marvels of engineering, expressions of human ingenuity, and symbols of enduring value. To understand their price, you must look beyond accuracy and into the world of craftsmanship, tradition, and emotional resonance.

The Core Difference: How They Work

Quartz and mechanical watches operate on fundamentally different principles. A quartz movement relies on a battery-powered electronic oscillator regulated by a tiny quartz crystal. When electricity passes through the crystal, it vibrates at a precise frequency—32,768 times per second—which an integrated circuit counts and converts into one pulse per second to drive the hands.

In contrast, a mechanical watch uses a tightly wound spring (the mainspring) to store energy. This energy is released gradually through a series of gears and regulated by a balance wheel and escapement mechanism. The entire system operates without batteries or electronics, relying solely on physics and precision machining.

This distinction sets the foundation for everything that follows—from manufacturing complexity to maintenance needs and, ultimately, cost.

Tip: If ultimate accuracy is your priority, choose quartz. But if you value craftsmanship and legacy, mechanical may be worth the investment.

Why Mechanical Watches Cost More: The Hidden Factors

The price gap between mechanical and quartz watches isn't arbitrary—it reflects tangible differences in design, labor, and materials. Below are the key reasons mechanical timepieces command such high prices.

1. Handcrafting and Labor Intensity

A single mechanical movement can contain over 200 individual parts, many smaller than a grain of rice. These components—gears, levers, springs, screws—are often machined, finished, and assembled by hand. Even in factories with modern CNC equipment, final assembly and regulation require skilled watchmakers who spend hours adjusting tolerances measured in microns.

For luxury brands like Patek Philippe, Audemars Piguet, or Jaeger LeCoultre, much of the finishing is done manually: anglage (beveling edges), perlage (circular graining), and Côtes de Genève (striped decoration). These finishes serve no functional purpose but reflect centuries-old traditions of horological artistry.

“Watchmaking is where engineering meets poetry. You’re not just building a machine—you’re creating something that will outlive its maker.” — François-Paul Journe, Independent Watchmaker

2. Materials and Precision Engineering

High-end mechanical watches use premium materials: 316L stainless steel, sapphire crystals, titanium, gold, platinum, and even ceramic. But the real expense lies beneath the surface—in the movement itself.

Bearings may use synthetic rubies to reduce friction. Balance springs are made from specialized alloys like Nivarox or silicon, resistant to temperature changes and magnetism. Some brands develop proprietary materials, such as Rolex’s Parachrom hairspring or Omega’s Si14 silicon oscillator, which take years and millions in R&D to perfect.

Tolerances in mechanical movements are astonishingly tight—often within ±5 microns (0.005 mm). Achieving this level of consistency requires advanced tooling, clean-room environments, and rigorous quality control.

3. Low Production Volumes and High Overheads

Unlike quartz watches, which are mass-produced in automated facilities by the millions, mechanical movements are typically made in limited numbers. A top-tier Swiss manufacturer might produce only 10,000–20,000 movements per year—compared to hundreds of millions of quartz units annually.

Low volume means higher per-unit costs. Facilities, skilled labor, and research investments must be recouped across fewer products. Additionally, certification processes like COSC (Contrôle Officiel Suisse des Chronomètres) add cost. While not all mechanical watches are COSC-certified, those that are undergo 15 days of testing in multiple positions and temperatures—a process that increases production time and expense.

Accuracy: Quartz Wins, But Context Matters

There’s no denying it: quartz watches are more accurate. A standard quartz movement averages ±15 seconds per month. High-accuracy variants, like Citizen’s Chronomaster or Grand Seiko’s 9F series, achieve ±10 seconds per year. In comparison, even a COSC-certified mechanical watch is allowed to deviate by -4/+6 seconds per day—an order of magnitude less precise.

Yet accuracy alone doesn’t define value. Consider a Stradivarius violin. It doesn’t play “better” in terms of pitch perfection than a modern factory-made instrument. But musicians and collectors prize it for tone, history, and craftsmanship. Similarly, mechanical watches are valued for their soul—the subtle rhythm of the ticking, the visible motion of gears, the connection to centuries of horological evolution.

Environmental Sensitivity and Regulation

Mechanical watches are affected by gravity, position, temperature, magnetism, and wear. A watch may run faster lying face-up than when worn on the wrist. That’s why fine timepieces are adjusted in multiple positions during manufacturing. Still, they require regular servicing—every 5 to 7 years—to maintain performance.

Quartz watches, meanwhile, are largely immune to these variables. Their oscillators are stable, consistent, and unaffected by orientation. However, they depend on batteries, which degrade over time and eventually fail. Most quartz movements last 10–15 years before electronic components begin to deteriorate, after which replacement is often cheaper than repair.

Real Example: The Long-Term Ownership Experience

Consider two friends: Mark buys a $300 Casio G-Shock with atomic timekeeping and solar charging. Sarah invests $8,000 in a vintage-inspired Omega Seamaster with a mechanical movement.

Over five years, Mark’s watch never needs attention. It syncs daily with radio signals, maintaining near-perfect time. Sarah takes her Omega in for service after four years. The bill is $600, covering disassembly, cleaning, oiling, reassembly, and regulation.

Yet when Sarah winds her watch each morning, she feels connected to its inner workings. She admires the sweeping second hand, the intricate rotor spinning behind a sapphire caseback, and the fact that her great-grandchildren could inherit it. Mark appreciates his watch’s reliability but sees it as disposable tech.

Both choices are valid. But only one transcends utility.

Expert Insight: The Emotional Economy of Time

“In horology, we trade precision for poetry. People don’t buy mechanical watches because they keep better time—they buy them because they mean something. Each tick is a reminder that humans can create beauty from necessity.” — Dr. Rebecca Struthers, Horological Historian and Watch Restorer

How to Decide: A Practical Checklist

If you're torn between mechanical and quartz, ask yourself the following. Check off what applies:

• ☐ I prioritize accuracy above all else.
• ☐ I want a watch that can be passed down as an heirloom.
• ☐ I appreciate fine craftsmanship and visible mechanics (e.g., exhibition casebacks).
• ☐ I’m willing to service my watch every few years.
• ☐ I value tradition and brand heritage.
• ☐ I prefer low-maintenance, set-and-forget timekeeping.
• ☐ I live an active lifestyle where durability is key.
• ☐ I see my watch as a piece of wearable art.

If most checked boxes are on the bottom half, a mechanical watch aligns with your values. If the top dominates, quartz—or even a smartwatch—might be the smarter choice.

Frequently Asked Questions

Can a mechanical watch ever be as accurate as quartz?

Not consistently under normal conditions. Even chronometer-grade mechanical watches vary more than basic quartz models. However, high-end innovations like tourbillons or silicon components improve stability. For true precision, though, nothing beats quartz or radio-controlled/smart-synced watches.

Are expensive mechanical watches worth the money?

Financially, most are not “worth” their price tag in utilitarian terms. But emotionally and culturally, yes—for enthusiasts, collectors, and those who value longevity and artistry. Some models even appreciate in value, especially limited editions from Rolex, Patek Philippe, or independent makers.

Do quartz watches have any advantages besides accuracy?

Absolutely. They’re generally thinner, lighter, more durable, and require far less maintenance. Many feature advanced functions like perpetual calendars, GPS time sync, alarms, and connectivity. For practical daily wear, especially in demanding environments, quartz remains the logical choice.

Conclusion: Beyond the Numbers

The question of why mechanical watches are expensive compared to quartz isn’t really about cost or accuracy—it’s about what we assign value to as humans. We pay not for seconds gained or lost, but for stories told through metal and motion. We honor the hands that shaped each gear, the generations of knowledge encoded in a balance spring, and the quiet rebellion of choosing analog in a digital age.

Quartz watches excel at measuring time. Mechanical watches remind us that time is also meant to be felt.
