Introduction

Here at WatchObsession, we live and breathe timepieces. From the intricate dance of gears in a classic mechanical watch to the sleek precision of a modern quartz movement, we appreciate the beauty and engineering in all its forms. But a question that often pops up amongst enthusiasts, and those new to the world of watches, is a fundamental one: Which movement takes the crown?


Is it the heritage of a traditional hand-wound watch? The ease of an automatic movement? Or the pure, unadulterated accuracy, of a quartz watch?


Which type of movement comes out on top – quartz, mechanical, or automatic? It's a debate that sparks passion, and while personal preference has the biggest impact on everyones overall answer, let's put that aside for a moment and dive into the nitty-gritty of keeping time.

Quartz vs. Mechanical vs. Automatic: Which Watch Movement Should You Choose?

The Quartz Contender: Precision Perfected?

The Battery Powered Quartz Movement


Born in the late 1960s, the quartz movement started a revolution that shook the traditional watchmaking world. Instead of relying on a mainspring and intricate gear train, a quartz movement utilise a battery to send an electrical current through a small quartz crystal. This crystal vibrates at an incredibly consistent frequency – precisely 32,768 times per second. These vibrations are then measured by a circuit and translated into the steady ticking of the second hand.


The Verdict on Quartz Accuracy: In the realm of everyday timekeeping, quartz movements are the undisputed champions. Their inherent design, based on the stable oscillations of a crystal, leads to exceptional accuracy, often within +/- 15 seconds per month, and sometimes even better in high-end quartz models. They are largely unaffected by factors like temperature fluctuations or the watch's orientation, which can impact mechanical movements.




The Mechanical Marvel: The Art of the Beat

Hand Wound Mechanical Movements


Mechanical watches, the heart of traditional horology, operate on a completely different principle. They rely on a wound mainspring that gradually releases energy through a complex system of gears, springs, and levers, culminating in the rhythmic ticking of the escapement. The precision of a mechanical watch is dependent on the meticulous craftsmanship and regulation of these tiny components.


The Verdict on Mechanical Accuracy: While undeniably beautiful and steeped in history, mechanical watches generally don't achieve the same level of pinpoint accuracy as their quartz counterparts. A well-regulated mechanical watch might aim for accuracy within +/- a few seconds per day, but this can be influenced by various factors, including the wearer's activity level, the watch's position, and even temperature.





The Automatic All-Rounder: Self-Winding Sophistication

Movement Powering the Movement


Automatic watches are essentially a subset of mechanical watches. The key difference lies in their ability to wind themselves. Instead of manual winding, an automatic watch utilises a rotor that spins with the natural motion of the wearer's wrist. This kinetic energy is then transferred to wind the mainspring.


The Verdict on Automatic Accuracy: In terms of accuracy, automatic watches fall within the same spectrum as manual-winding mechanical watches. While the convenience of self-winding is a significant advantage, it doesn't inherently improve the fundamental accuracy of the mechanical movement itself. Like their manually wound brethren, their accuracy is subject to the same influencing factors.





The Pros and Cons: Helping You Chose a Movement

Quartz

Mechanical

Automatic

Pros

  • Superior Accuracy: Unmatched in daily timekeeping, often only gaining or losing a few seconds per month.
  • Affordability: Generally the most cost-effective to produce, making them widely accessible.
  • Low Maintenance: The movement requires minimal servicing and only need a battery replacement every few years.
  • Durability: Fewer moving parts make them more resistant to shocks and less sensitive to external factors like temperature.
  • Convenience: Ready to wear anytime without winding, and can be left unworn for extended periods without stopping.

Pros

  • Traditional Craftsmanship & Artistry: Highly valued for their intricate engineering, visible mechanics, and the skilled labor involved in their creation.
  • No Batteries: The movement is powered by a wound mainspring, eliminating the need for battery changes.
  • Longevity & Heirloom Potential: Can last for generations with proper care and servicing, often appreciating in value.
  • "Sweeping" Second Hand: The movement of the second hand is a smooth, continuous sweep, which is aesthetically pleasing to many.
  • Personal Connection: Many enjoy the ritual of manually winding the watch daily, feeling a deeper connection to the timepiece.

Pros

  • Self-Winding Convenience: Winds itself with the motion of the wearer's wrist, eliminating the need for daily manual winding if worn regularly.
  • No Batteries: Like watches with mechanical movements, they are powered by kinetic energy, so no battery changes are needed.
  • Traditional Craftsmanship: Shares the same appreciation for intricate mechanical engineering as manual wind watches.
  • "Sweeping" Second Hand: Features the smooth, continuous sweep of the second hand.
  • See-Through Casebacks: Many models have a display caseback, allowing the wearer to admire the rotor and movement.

Cons

  • Battery Dependence: Requires battery replacement, which can be an added cost and inconvenience.
  • Lack of Traditional Craftsmanship: Many enthusiasts feel they lack the artistry and intricate engineering of mechanical movements.
  • "Dead Beat" Second Hand: The second hand typically moves in distinct "ticks" rather than a smooth sweep, which some find less appealing.
  • Environmental Impact: Battery disposal contributes to electronic waste.

Cons

  • Less Accurate: Generally less precise than quartz movements, often gaining or losing several seconds per day.
  • Requires Regular Winding: Must be manually wound every 24-72 hours (depending on power reserve) to keep running.
  • Higher Maintenance & Cost: More complex movements require periodic servicing (every 3-5 years) by a skilled watchmaker, which can be expensive.
  • Susceptible to Shock: Delicate internal components can be more easily damaged by impacts.
  • Thicker/Heavier: Tend to be thicker and heavier due to the numerous parts and mainspring.

Cons

  • Less Accurate: Similar to manual mechanical watches, they are less accurate than quartz movements and can gain or lose seconds daily.

  • Can Stop if Not Worn: If left unworn for an extended period (beyond its power reserve), it will stop and need to be reset. A watch winder can mitigate this.

  • Higher Maintenance & Cost: Requires similar periodic servicing to manual mechanical watches, which can be costly.

  • Thicker/Heavier: The added rotor mechanism often makes automatic watches slightly thicker and heavier than manual or quartz movements.

  • Susceptible to Shock: Also prone to shock damage due to their complex mechanical nature.

So, Which Movement Takes the Crown?

If absolute accuracy is your primary concern, then a watch with a quartz movement undeniably take the crown. Their fundamental design offers a level of precision that mechanical and automatic watches simply cannot consistently match in everyday use.


However, the world of watches is about so much more than just accuracy. The intricate mechanics of a mechanical or automatic movement, the heritage, the craftsmanship, and the sheer artistry involved offer a different kind of value and connection to timekeeping.


Ultimately, the "better" watch depends on your priorities. If you demand unwavering precision, quartz is your go-to. If you appreciate the beauty of engineering and the romance of a handcrafted movement, then a mechanical or automatic watch will undoubtedly capture your heart.

Frequently Asked Questions

Which movement is right for me?

Choosing a watch is an incredibly personal choice, with each movement having it's own pros and cons.

The best way to decide which movement is best for you is to take the key points from the above blog and ask yourself what is most important to you.

How long do watch batteries last?

A watch with a traditional quartz powered movement can last anywhere between 2 and 5 years. This timescale relies heavily on the duties of the watch, more complications, such as chronographs, dates and GMT hands can shorten the lifespan of the battery.


If longevity is your goal when choosing a watch, look for a solar powered quartz movement; the batteries of these watches have are recharged by the sun and can last much longer than their non solar counterparts, some up to 25 years!

Are quartz watches cheaper than the others?

Yes and no, although most watches on the more affordable end of the scale are quartz powered, there are also many quartz watches costing in the hundreds of thousands. There are also mechanical and automatic movement watches available for less that £100. The price isn't the main factor in choosing between the three movements.
