What is a Mechanical Watch and How Do They Work?

Have you ever wondered how a watch can keep perfect time without a battery? The answer lies in the fascinating world of mechanical watches. These timeless pieces of craftsmanship have been around for centuries, captivating watch enthusiasts with their intricate inner workings and enduring appeal.

At Sylvi, we celebrate the art and science behind these marvels. Let's dive into the enchanting realm of mechanical watches and discover what makes them tick.

Mechanical watches are timeless pieces of craftsmanship, revered for their intricate mechanics and elegance. They cater to both men and women, offering a range of styles from the best mechanical watches for men to sophisticated mechanical watches for women. Each watch is a testament to precision and artistry, making it a prized possession for any watch enthusiast. Whether you're seeking a classic timepiece or a modern marvel, mechanical watches remain a symbol of luxury and excellence.

What is a Mechanical Watch?

A mechanical watch relies on a clockwork mechanism to keep time, distinct from a quartz watch, which uses a battery. Central to the mechanical watch is the mainspring, which, when wound, stores energy that powers the balance wheel. The gear train transmits this energy and calculates the oscillations that measure seconds, minutes, and hours. The escapement then releases the wheels incrementally, ensuring the hands move at a consistent rate. This escapement mechanism is also responsible for the characteristic ticking sound of mechanical watches.

Mechanical watches typically have a smooth, sweeping seconds hand, in contrast to the individual ticks of a quartz watch. Although some high-end mechanical watches are designed to feature a ticking movement to showcase advanced watchmaking, this is generally uncommon.

Modern mechanical watches often incorporate synthetic jewels, such as garnet, quartz, sapphire, or ruby, to minimize friction within the movement. This reduces wear and tear, enhancing both the accuracy and longevity of the watch components. These jewels, visible through exhibition case backs, are strategically placed throughout the movement, highlighting the intricate craftsmanship of the watch.

How Mechanical Watches Work?

Mechanical watches captivate enthusiasts with their intricate, purely mechanical operation, functioning independently of batteries. They rely on a series of interconnected components working in perfect harmony to measure time accurately.

At the core of a mechanical watch lies the mainspring, a coiled metal spring that stores energy crucial for the watch's operation.

Winding the Mainspring

  1. Manual Winding: In manually wound watches, the wearer must turn the crown to wind the mainspring. This action tightens the spring, storing potential energy that powers the watch.

  2. Automatic Winding: Automatic or self-winding watches feature a rotor, a metal weight that oscillates with the movement of the wearer’s wrist. This motion winds the mainspring, eliminating the need for manual winding and ensuring the watch remains powered with regular use.

Energy Transfer Through the Gear Train

Once wound, the mainspring releases its stored energy slowly and evenly. This energy is transferred through the gear train, a series of gears designed to reduce the speed of the mainspring’s unwinding. This controlled release of energy is crucial for ensuring the watch keeps accurate time.

Role of the Escapement in Regulating Time

The escapement is a pivotal component in mechanical watches. It regulates the energy released from the mainspring to the gear train, controlling the motion of the gears. By releasing energy in precise, timed intervals, the escapement ensures that the watch maintains consistent timekeeping.

Oscillation of the Balance Wheel

The balance wheel works in tandem with the escapement to regulate time. It oscillates back and forth at a steady rate, much like a pendulum. The consistent oscillation of the balance wheel drives the precise movement of the watch’s hands.

Movement of the Hands to Display Time

The dial train, connected to the gear train, transfers the controlled movement to the hands of the watch. This causes the hands to move smoothly around the dial, displaying the hours, minutes, and seconds. The intricate coordination of these components results in the accurate and reliable timekeeping that mechanical watches are renowned for.

The mechanical watches embody this complex engineering, delivering precision and reliability wrapped in elegant design. Whether you prefer the tradition of manual winding or the convenience of automatic winding, our collection offers something for every watch enthusiast.

Types of Mechanical Watches For Men & Women

Mechanical watches come in two primary types: manual and automatic, each catering to different preferences and lifestyles.

Manual Mechanical Watches

Manual mechanical watches require regular hand-winding. Turning the crown tightens the mainspring, which powers the watch. This ritual appeals to enthusiasts who enjoy hands-on interaction with their timepieces. Additionally, manual watches often feature a thinner profile, as they lack the rotor mechanism found in automatic watches.

Automatic Mechanical Watches

Automatic watches, or self-winding watches, harness the motion of the wearer's wrist to wind the mainspring. The integrated rotor moves with each watch movement, winding the watch automatically. This feature offers convenience for those who wear their watch regularly and prefer to avoid daily manual winding.

Differences Between Manual and Automatic Watches

Mechanical watches, though based on the same foundational principles, differ significantly in their winding mechanisms, maintenance requirements, and design features.

Winding Mechanism

  • Manual watches necessitate regular hand-winding, requiring the wearer to turn the crown to keep the watch running. In contrast, automatic watches wind themselves through the natural motion of the wearer's wrist, thanks to a built-in rotor that oscillates with movement.


  • Automatic watches must be worn frequently or stored in a watch winder to maintain their charge. If left unworn, they will eventually stop and need to be manually wound to restart. Manual watches, on the other hand, require consistent winding by the user, typically on a daily basis, to ensure they keep accurate time.


  • Manual watches are often prized for their simplicity and typically feature a thinner case, as they lack the additional components found in automatic watches. Automatic watches include a rotor and other self-winding mechanisms, which can make them slightly thicker.

Advantages of Mechanical Watches

  • With proper care, mechanical watches can last for decades, even generations.
  • They showcase the intricate skill and artistry of watchmaking, featuring complex inner workings.
  • No batteries are needed, reducing electronic waste and promoting sustainability.
  • Often appreciated over time, especially limited editions or prestigious brands, making them valuable collectables.
  • Combines reliability, beauty, and precision, offering a timeless addition to any collection

Importance of Regular Servicing

Regular servicing is crucial to ensure the accuracy and longevity of a mechanical watch. Over time, the lubricants that keep the watch’s internal mechanisms running smoothly can degrade or dry out, leading to increased friction and wear on the parts. Additionally, various components may experience wear and tear. Servicing a mechanical watch usually entails a meticulous process: the watch is disassembled, each part is cleaned and lubricated, and any necessary adjustments are made to restore optimal performance. To keep a mechanical watch in top condition, it's typically recommended to have it serviced every 3 to 5 years.


Best Mechanical watches offer a timeless appeal and intricate craftsmanship, making them a preferred choice for both men and women. Whether you're searching for the best men’s or women’s mechanical watches, these timepieces stand out for their precision and style. Embrace the enduring charm and sophistication that a mechanical watch brings to your collection.
