Timekeeping Demystified: Understanding Quartz & Automatic Watches and How to Care for Them

Watches have come a long way from being mere timekeeping devices to being a statement of style and craftsmanship. Among the options available, quartz and automatic watches are two popular choices for watch enthusiasts. But what exactly sets them apart, and how do you care for them to ensure they last a lifetime? In this informational how-to guide, we’ll delve into the differences between quartz and automatic watches, and provide you with essential care tips to keep your timepiece ticking for years to come.

Understanding Quartz Watches:

Quartz watches are known for their accuracy and reliability. They are powered by a battery that sends electrical currents through a quartz crystal, causing it to vibrate and generate a precise frequency that regulates the watch’s timekeeping. 

Quartz watches typically require minimal maintenance and are known for their ease of use. They are often characterized by their sleek and modern designs, making them a popular choice for everyday wear.

Quartz watches are made up of these components: 

  1. Power Source: A quartz watch is powered by a battery, usually a small coin-cell battery, which provides the electrical energy needed for the watch to function.

  2. Quartz Crystal: The heart of a quartz watch is a small, thin piece of quartz crystal, typically in the shape of a tuning fork or a small cylinder. The quartz crystal is made of silicon dioxide, which is a naturally occurring mineral with piezoelectric properties. Piezoelectricity is the ability of certain materials to generate an electrical charge when subjected to mechanical stress or pressure, and vice versa.

  3. Oscillator: The quartz crystal is used as an oscillator in the watch. When an electrical voltage is applied to the quartz crystal, it vibrates at a very high frequency, typically in the range of 32,768 Hz (hertz), which means it oscillates or vibrates 32,768 times per second. These vibrations are extremely regular and consistent, which makes quartz crystals ideal for timekeeping.

  4. Frequency Divider: The high-frequency vibrations of the quartz crystal are too fast to be used directly for timekeeping, so they need to be divided down to a more manageable frequency. A frequency divider circuit in the watch’s electronic module is used to divide the high-frequency vibrations of the quartz crystal down to a lower frequency, typically 1 Hz or 1 pulse per second.

  5. Integrated Circuit (IC): The heart of the electronic module in a quartz watch is an integrated circuit (IC) or microchip, which contains various electronic components such as transistors, capacitors, and resistors. The IC is responsible for generating the electrical signals that drive the watch’s hands or display.

  6. Feedback Loop: The quartz crystal and the frequency divider are connected in a feedback loop with the IC. The IC sends a small electrical pulse to the quartz crystal, which causes it to vibrate at its natural frequency. The frequency divider then divides down the high-frequency vibrations of the quartz crystal to a lower frequency, and this lower frequency is fed back to the IC. The IC compares the feedback frequency with a reference frequency, typically 1 Hz, and uses the difference between the two frequencies to keep time accurately.

  7. Timekeeping: The IC uses the feedback loop to generate a series of electrical pulses at a rate of 1 Hz, which represents one second per pulse. These pulses are then used to drive a stepper motor or a liquid crystal display (LCD) to move the watch’s hands or display the time digitally.

  8. Additional Functions: Quartz watches may also have additional functions such as date display, alarm, stopwatch, and other features, which are controlled by the IC and other electronic components in the watch.

Demystifying Automatic Watches

An automatic watch, also known as a self-winding watch, is a type of mechanical watch that uses the movement of the wearer’s arm to power the watch’s movement and keep time

Automatic watches are revered for their intricate mechanics and craftsmanship. Unlike quartz watches, automatic watches are powered by the natural motion of the wearer’s wrist. As the wrist moves, a rotor inside the watch winds the mainspring, storing energy that powers the watch. 

Automatic watches are often prized for their traditional and timeless appeal, and are considered a symbol of luxury and sophistication.

Automatic watches are made up of these components: 

  1. Main Spring: The main source of power in an automatic watch is a tightly wound main spring, which is typically made of a long, coiled strip of metal. The main spring stores potential energy when it is wound manually or by the motion of the wearer’s arm.

  2. Rotor: An automatic watch has a rotor, which is a weighted disc that is connected to the movement of the watch. The rotor is free to rotate and is mounted on a central pivot. As the wearer moves their arm, the rotor spins in response to the motion.

  3. Ratchet Mechanism: The rotor is connected to a ratchet mechanism, which is designed to only allow the rotor to rotate in one direction, typically clockwise. The ratchet mechanism uses a system of gears or pawls that engage with the rotor and allow it to rotate in the winding direction, but prevent it from rotating in the opposite direction.

  4. Gear Train: The rotor drives a gear train, which is a series of gears that transmit the energy from the spinning rotor to other parts of the watch movement. The gear train serves to transfer the rotational energy from the rotor to different components in a controlled manner.

  5. Oscillating Weight: The spinning rotor creates an oscillating or swinging motion, which causes an oscillating weight to move back and forth. The oscillating weight is connected to the gear train and winds the main spring as it moves.

  6. Main Spring Barrel: The main spring is housed in a barrel, and as the oscillating weight winds the main spring, the potential energy in the main spring increases. The main spring barrel acts as a power reserve, storing the energy that will be used to power the watch’s movement.

  7. Escapement: The gear train drives the escapement, which is a mechanical device that regulates the release of energy from the main spring barrel to the watch’s timekeeping mechanism. The escapement controls the speed at which the watch’s gears turn and ensures that the watch keeps accurate time.

  8. Balance Wheel: The escapement is connected to a balance wheel, which is a circular wheel with a hairspring. The balance wheel oscillates back and forth, driven by the release of energy from the main spring, and its oscillations are regulated by the escapement

The balance wheel and escapement work together to control the release of energy from the main spring in a controlled manner, which drives the watch’s hands or other timekeeping mechanism to indicate the time.

As long as the watch is worn and the wearer’s arm is in motion, the rotor continues to spin and wind the main spring, maintaining the power reserve of the watch. This continuous winding ensures that the watch remains powered and keeps accurate time as long as it is worn regularly.

Caring for Your Quartz Watch

Proper care and maintenance are crucial to keep your quartz watch in optimal condition. Here are some essential care tips:

a) Regular Battery Replacement: Quartz watches require battery replacement every 1-2 years, depending on the brand and model. It’s recommended to have the battery replaced by a professional watchmaker to ensure proper sealing and water resistance.

b) Avoid Magnetic Fields: Quartz watches can be sensitive to magnetic fields, which can affect their accuracy. Avoid placing your quartz watch near strong magnetic fields such as speakers, refrigerators, or magnets.

c) Water Resistance: Check the water resistance rating of your quartz watch and avoid exposing it to water beyond its recommended limits. Avoid swimming or showering with a non-waterproof quartz watch to prevent damage to the movement.
