Did you know that complex mechanical watches contain hundreds of microscopic parts? Fitting the sheer number of parts in a small watch case means engineering parts require optical aids to assemble. Despite all these delicate mechanical parts, a mechanical watch functions for days, powered by your physical movements.
This guide will explain how these parts work together to provide a seamless display of precision and reliability. We will explore everything from the basics to storing energy and final oscillation. These features allow the mechanical watch to maintain its accuracy and reliability.
Mechanical watches are powered using a tightly wound metal strip known as the mainspring. It holds the potential energy that is converted to drive the watch hands. As the strip unwinds, the energy travels through the gear train. The system transforms the slow unwinding movements of the coiled strip into the rapid, continuous rotation of the watch hands.
To keep the time accurate, the watch consists of a balance wheel. It acts like a heartbeat with consistent back-and-forth movements. It's exactly 28,800 vibrations per hour (vph). To ensure all the power from the spring is not extracted at once, a controlling mechanism called escapement is used. It uses the energy in tiny amounts, creating the signature ticking sound.
All the pieces are made using metals, which makes them last for generations. Luxury versions come with synthetic rubies. These jewels rank 9 on a Mohs hardness scale. Their hardness provides protection against rubbing frictions that would wear down the metal.
The manual watches require physical winding to function. It's simply a small knob on the side of the watch crown to add potential energy to the mainspring. In comparison, automatic watches have a large, heavy semi–circular weighted rotor. It spins with the hands' natural movements to wind the mainspring.
As automatic watches have a higher number of components and require a swinging weight attached to the winding gear system, it needs more internal space. It causes the watches to have a thicker body in comparison to manual watches.
Manual watches have a lower number of components. It means if there is no swinging block inside the watch, you can use a clear glass back to showcase the internal mechanics at work.
The first ever perpetual rotor self-winding mechanism was invented and patented by Rolex. In the year 1931, it was one of the greatest inventions in watchmaking that set the standard for modern automatic and luxury watches today.
If we go back to the 17th century, the minute repeater or the musical chiming feature was originally invented out of necessity. It was developed to allow watch owners to determine the time in total darkness. The function provided time long before luminous dials became common. It was considered an extra watch feature.
In horology, any feature that does more than just display basic hours, minutes, and seconds is considered extra and referred to as a complication. The everyday watches have small complications like the date window, day of the week, or a power reserve indicator.
Advanced watches may feature grand complications. As these features require additional interlocking gears these require a complex and larger housing. They are often compared to “miniature Rube Goldberg machines.
The amount of time that the watch can continue to work from the moment the mainspring is fully wound to the time the watch completely stops is called power reserve. A typical watch will have a running time that lasts 38 to 48 hours. Complex timepieces that feature spring barrels can run continuously for 70 hours or even up to 10 days on a single wound. Here are some features related to power reserve in modern watches:
Monitoring Power: Watch owners can track the energy that the watch has through a visual display. It lets you know that the watch is fully wound or it needs to be wound again.
Safety Feature: In modern watches, owners don't need to worry about over-torquing the mainspring. These watches have a mechanism called a slipping clutch that allows the power spring to safely slide when it reaches 100% capacity.
* Unique Material Insight: The hairspring that regulates time is made using Nivarox. It does not expand or contract with temperature changes, resulting in accurate timekeeping.
A watch that has a built-in stopwatch is known as a chronograph. It operates through the pushers on the side of the watch. It allows users to start and stop the timer from the top button and reset everything to zero from the bottom one. To keep the stopwatch time separate from the daytime, it uses small secondary dials called totalizers. Some may even have a tachymeter scale on the outer ring to allow calculation of speed and distance.
Automatic mechanical watches rely on motion for their winding mechanism. To prevent the gravity from changing the watch's accuracy, watchmakers invented a tourbillon. It counteracts the pull generated from gravity, especially in a vertical position. It works by placing the watches' delicate time components inside a rotating cage that turns a full 360 degrees. It typically completes one rotation every 1 minute. As the tourbillon rotates, the timing organ in all vertical positions, the gravity impact is effectively averaged out and canceled over the course of each minute.
These are mesmerizing mechanisms that require master craftsmanship. Watches with a tourbillon are the most prestigious and expensive watches in the world.
Some watches feature a fully automated date system. It corrects itself for months containing 28, 30, and 31 days. Some even account for the leap years. Producing accurate dates requires highly complex movements. There are tiny internal parts like date wheels, levers, and month racks. The whole mechanism is labor-intensive and complex to manufacture, making them more expensive than standard calendar watches.
Moon phase is a watch feature that shows the current waxing and waning stage of the moon. A small window on the dial displays the moon phase complication. Mechanical watches that feature moon phase rely on a specific 59-tooth gear that turns a disc displaying the moon. It completes one full cycle every 29.5 days. The earliest known device for tracking lunar phases was the Antikythera mechanism, which dates back to 150 BC.
For frequent travelers, getting lost in time is an everyday challenge. To ensure that the watch tracks the various time zones at once, these watches come with a dedicated 24-hour hand and a corresponding rotating outer scale. These are called GMT watches. They track a second time zone independently. Other designs may have dual time, which incorporates a 12-hour standard secondary dial.
It's important that we evaluate our daily habits to match them with horology. For active individuals, choosing an automatic watch with high water resistance and Incabloc technology is key. In case you desire physical touch and tactile feel from the watch, then standard manual watches should be the go-to choice.
For frequent travelers, being in the same time zone is vital. Tracking meeting time across the globe is much more convenient with GMT. There is no need for manual resetting of the dial, and it has enough information to allow tracking multiple zones through perpetual calendars.
Consider your watch as a lifelong investment. It needs professional service every 3 to 5 years for accuracy. The delicate components that make up the watch need cleaning and lubrication to revive their time accuracy and powering mechanisms.
Mechanical watches are a mesmerizing display of craftsmanship. It provides owners escape from the digital world and takes them back into the era of mechanical perfection. Having a watch that powers through your movements forms a connection. With features like tourbillon, chronographs, perpetual calendars, moon phase functions, and GMT fulfills all the users' needs. The watch provides a sense of appreciation for human ingenuity. If you have the budget, then consider mechanical watches. They are the true representation of watchmaking expertise.
