How is a Watch “Water-Resistant”?

All FAE Wristwatches are water-restistant. But what does that mean? How does a watch resist water?

A watch is considered “water-resistant” when it is designed and constructed to withstand exposure to water to a certain extent. The water resistance of a watch is measured in units of pressure, typically expressed in meters, feet, or atmospheres (ATM).

To make a watch water-resistant, several features and techniques are employed:

  1. Gaskets and Seals: The watch case, crystal, and crown (the knob used for setting the time) are fitted with gaskets or O-rings made of rubber or silicone. These gaskets create a watertight seal and prevent water from entering the watch.
  2. Screw-down Crown: Many water-resistant watches have a screw-down crown. When the crown is pushed in and screwed down tightly, it creates a seal that helps prevent water from penetrating the case.
  3. Case Design: Water-resistant watches typically have a sturdy and well-sealed case design. The case back is often screwed down or secured with a gasket to ensure water resistance.
  4. Crystal: The watch crystal, which covers the dial, can be made from various materials such as acrylic, mineral glass, or synthetic sapphire. Synthetic sapphire is highly scratch-resistant and offers excellent water resistance.
  5. Water-Resistant Movement: The watch movement itself may be designed with special seals and lubricants to protect it from moisture and water damage.

It’s important to note that water resistance is not a permanent feature of a watch and can deteriorate over time due to wear, aging of gaskets, or damage to the seals. Also, water resistance is tested under laboratory conditions and may not guarantee the watch’s performance in real-world situations, such as rapid temperature changes, extreme depths, or underwater activities.

Water-Resistance Rating

Manufacturers usually specify the water resistance rating of a watch, indicating the depth to which it can be safely submerged. Common water resistance ratings include:

  • 30 meters (3 ATM or 100 feet): Suitable for everyday use, but not suitable for swimming or diving.
  • 50 meters (5 ATM or 165 feet): Can be worn while swimming in shallow water.
  • 100 meters (10 ATM or 330 feet): Suitable for recreational swimming and snorkeling.
  • 200 meters (20 ATM or 660 feet): Suitable for recreational scuba diving.
  • 300 meters (30 ATM or 990 feet) or higher: Suitable for professional diving and extreme water sports.

It’s important to check the watch’s water resistance rating and follow FAE guidelines to ensure your watch remains water-resistant. Of most importance, make sure to get your Annual Maintenance done on time, as this includes a new Case Back O-Ring Gasket which helps ensure long-term water-resistance.

How Does a Watch Mainspring Work?

A watch’s mainspring is a crucial component of its mechanical movement, providing the necessary power to drive the timekeeping mechanism. It’s a coiled spring made of a special alloy, typically steel or a composite material, with excellent elasticity properties.

The mainspring is housed in a cylindrical barrel, and one end of the spring is attached to the barrel while the other end is fixed to the watch’s gear train. When the mainspring is wound, either manually or through an automatic winding system, potential energy is stored in the coiled spring.

As the mainspring unwinds, it releases the stored energy gradually, transmitting power through the gear train. The gear train consists of a series of gears that transfer the rotational energy from the mainspring to the escapement mechanism. The escapement regulates the release of this energy in precise increments, enabling the movement’s timekeeping functions.

The unwinding mainspring exerts torque on the gear train, causing the gears to rotate and transmit power to various components of the movement. This includes the balance wheel, which oscillates back and forth, and the escapement mechanism, which controls the rate at which the energy is released.

The mainspring’s torque diminishes as it unwinds, affecting the amplitude of the balance wheel’s oscillations. To maintain accurate timekeeping, watchmakers utilize various mechanisms, such as a fusee or a constant-force mechanism, to counteract the decreasing torque and ensure consistent power delivery to the escapement throughout the mainspring’s unwinding cycle.

In summary, a watch’s mainspring functions as an energy storage device, converting the manual or automatic winding into potential energy. This energy is then released gradually to power the movement’s various components, ensuring accurate timekeeping.

What Does a Pallet Fork Do?

A pallet fork is a crucial component in a mechanical watch’s escapement mechanism. The escapement is responsible for regulating the release of energy from the watch’s mainspring and ensuring the precise and controlled movement of the watch’s hands.

The pallet fork, along with the escape wheel, forms the core of the escapement system. The pallet fork engages with the teeth of the escape wheel, which is driven by the watch’s mainspring. As the escape wheel rotates, it pushes against the pallet fork, causing it to oscillate back and forth.

The pallet fork’s primary function is to control the release of energy from the mainspring in small, precise increments. It does this by engaging with the escape wheel’s teeth and allowing the wheel to rotate by a fixed amount before locking it in place momentarily.

During each oscillation of the pallet fork, it interacts with the impulse jewel, receiving a brief impulse of energy that further drives its oscillation. This impulse, combined with the oscillation of the balance wheel and the action of the hairspring, creates the necessary timing mechanism that regulates the watch’s timekeeping accuracy.

The precise engagement and locking action of the pallet fork with the escape wheel ensure that the watch’s energy is released at a constant rate, controlling the rotation of the gear train and ultimately the movement of the watch’s hands.

In summary, the pallet fork in a mechanical watch’s escapement mechanism plays a critical role in regulating the release of energy and maintaining the timekeeping accuracy of the watch.

Is Titanium Softer than Stainless Steel?

Answer: It depends on the Heat Treatment.

Titanium is not softer than stainless steel. In fact, titanium is generally harder than stainless steel. The hardness of a material is measured on the Mohs scale, and stainless steel typically has a hardness ranging from 4 to 5 on this scale. On the other hand, titanium has a hardness of about 6 on the Mohs scale, making it harder than most stainless steel alloys. On a third hand, heat-treated steel can reach a hardness of 7.

There are different types and grades of stainless steel and titanium, so the hardness may vary depending on the specific alloy. However, in general, untreated (non-hrat-treated) titanium is considered to be a harder material than untreated stainless steel.

Heat Treatment Matters

Unhardened titanium is generally softer than hardened stainless steel. When we talk about hardness, we refer to a material’s ability to resist indentation or scratching. Stainless steel is often hardened through processes such as heat treatment or cold working to increase its hardness. Hardened stainless steel can have a higher hardness level compared to unhardened titanium.

Unhardened titanium, in its pure form, is relatively soft compared to hardened stainless steel. However, it’s important to note that there are different grades and alloys of titanium and stainless steel, each with varying hardness levels. So, the specific comparison would depend on the particular grades of titanium and stainless steel being compared. Nonetheless, in general, hardened stainless steel is likely to be harder than unhardened titanium.

How a Watch Escapement Works

A watch escapement is a crucial mechanism in mechanical watches that regulates the release of energy from the mainspring and controls the movement of the watch’s hands. It consists of several components working together to ensure precise timekeeping. Here’s a simplified explanation of how a watch escapement works:

1. Mainspring: The mainspring is a coiled spring that stores potential energy when wound. As the mainspring unwinds, it releases this stored energy to power the watch.

2. Balance Wheel: The balance wheel is a wheel with a weighted rim that oscillates back and forth, creating a periodic motion. It acts as the timekeeping element of the watch, and its oscillations are what allow the watch to measure time.

3. Balance Spring: The balance spring, also known as the hairspring, is a fine coiled spring attached to the balance wheel. It provides the restoring force that keeps the balance wheel oscillating back and forth at a consistent rate.

4. Escape Wheel: The escape wheel is a toothed wheel that interacts with the pallet fork to control the energy flow. It rotates in small increments, known as “ticks,” driven by the unwinding mainspring.

5. Pallet Fork: The pallet fork is a lever that engages with the escape wheel teeth. It has two small prongs, called pallet jewels, which alternately lock and unlock the escape wheel teeth, controlling the movement of the escape wheel.

The interaction of the escape wheel and the pallet fork is the key to the escapement’s operation:

– Locking: As the balance wheel swings, the escape wheel rotates, and one of its teeth comes in contact with the pallet fork. This locks the escape wheel momentarily, stopping its rotation.

– Unlocking: The balance wheel continues its oscillation, causing the pallet fork to release the locked tooth of the escape wheel. The release of the tooth transfers a small amount of energy to the balance wheel, keeping it oscillating.

– Impulse: When the escape wheel tooth unlocks, the energy stored in the mainspring is transferred to the balance wheel, causing it to swing in the opposite direction. This transfer of energy is known as the “impulse,” and it maintains the oscillation of the balance wheel.

This process repeats with each swing of the balance wheel, creating a regular oscillation and precise timekeeping. The escapement effectively divides the unwinding of the mainspring into small, precise increments to ensure accurate timekeeping and control the speed of the watch’s movement.

It’s important to note that there are various types of escapements used in different watches, including the lever escapement, Swiss lever escapement, and co-axial escapement, among others. Each type has its own design and characteristics, but the fundamental principle of regulating energy flow remains similar across all escapements.
