Since their invention back in the 14th century, mechanical watches have evolved a lot, reducing their size until they can be worn on the wrist, but what exactly are they and how do they work? A mechanical watch can be basically defined as one that works thanks to a mechanical system of springs and gears, without depending on batteries or any other electronic device. Therefore, both automatic and wind- up watches fall into this group , but quartz watches and any other that uses a measurable natural phenomenon, such as the sun, are left out. Today mechanical watches are considered authentic works of art, a precision instrument whose operation is a spectacle of moving parts for those who know how to appreciate it. If you want to know more details about the history and operation of this micro-engineering masterpiece, we will tell you about it in this post.

In those days they were great machines that occupied a prominent place in some of the tallest towers in Italy and Great Britain. Very simple watches that used large gears driven by weights and regulated by Foliot -type mechanisms that at best deviated half an hour a day. Despite being imprecise and breaking easily, these mechanisms were quite an advance at the time and in fact, for more than 300 years it would be the predominant system, although with some updates. gear mechanical watch ➤ From the weights to the spring Changes like those introduced by Peter Henlein, a German locksmith from Nuremberg who swapped out the weights for winding springs sometime between 1504 and 1508. This considerably reduced the size of the mechanisms and allowed the appearance of the first portable mechanical watches. Designs that soon became very popular among the richest since they could be hung on the wall, on a table or even worn around the neck. Although these clocks were egg-shaped, they only had hour hands and no crystal, a feature that would not come onto the scene until the 17th century. spring mechanical watch ➤ The invention of the pendulum In 1656, the Dutch scientist Christian Huygens invented the first clock regulated by an oscillating pendulum mechanism, although the idea is also attributed to Galileo Galilei, who had already studied the pendulum movement in 1582.mechanical pendulum clock Although Galileo's designs for a pendulum clock never came to fruition, at least while he was alive. Huygens continued to refine his automatic watches and over the next few years managed to achieve a precision of less than 10 seconds per day. In fact, his 1675 balance wheel spring design can still be seen on some wristwatches today. Huygens' clock was the starting point for a race for precision that led to numerous advances, leading pendulum clocks to dominate timekeeping standards until the invention of the quartz clock in 1927. ➤ The mechanical pocket watch In parallel, Henlein's portable watches continued to evolve and in 1550, thanks to the use of screws, they were able to take the flat shape of the current pocket watch. Although it would not be until the year 1675 when these mechanical devices would be small enough to be carried in the pocket and not as a pendant. It is believed that Carlos II himself was the one who popularized this new way of transporting watches in Europe and North America. It is at this time that the first designs with glass protection appear and soon become luxury items, receiving great attention from designers and fashion experts. Although all these watches had a big problem, their lack of precision, something that the English watchmaker Thomas Mudge solved in 1755 by inventing the lever escapement. Thanks to this ingenuity, the mechanisms went from deviating several hours a day to just one or two minutes, which was a revolution in the watchmaking industry. mechanical pocket watches Therefore, it is not surprising that after 1820 the lever escapement was already present in most mechanical watches around the world and in fact it is still used today. In 1857, the first mass-produced pocket watches with standardized parts appeared, driven by the industrial revolution, allowing everyone to have access to cheap and reliable watches. The first designs used a key-winding system to wind the mechanism, but from 1860 the crown began to be used to power the watch. After the outbreak of World War II in 1914, wristwatches became fashionable and pocket designs became history. ➤ Mechanical wristwatches Many claim that the first wristwatch was designed by Abraham-Louis Breguet in 1810 as a gift to Caroline Murat (Queen of Naples), although there is also evidence of an armwatch, a gift from Robert Dudley to Queen Elizabeth I in 1571.mechanical wrist watch Regardless of which was the first, the truth is that before the First World War they were only considered a jewel-type bracelet for women. But the pocket watch was not made for the battlefield and the war highlighted the need for soldiers to carry a more practical instrument for combat. In fact, the first bracelet designs were nothing more than pocket watches modified with a leather strap so that they could be attached to the wrist. Soon after, numerous manufacturers such as Louis Cartier and Wilsdorf & Davis (later Rolex) began making wristwatches designed especially for the wrist. In this way, what began as a passing fad for men ended up becoming a revolution in the world of watchmaking, so much so that by 1930 wristwatches already outnumbered pocket watches 50 to 1. ➤ From mechanical to automatic In 1770 the Swiss watchmaker Abraham-Louis Perrelet devised a system of oscillating counterweights that allowed the watch to be wound automatically while its wearer walked. In fact, it was advertised as being effective enough to power the mechanism for 8 days with just a 15-minute walk. For this reason Perrelet has always been considered the father of the automatic watch, although for historians there is no record of what type of movement he created and they also point to the watchmaker Hubert Sarton, whose sketches and descriptions of the automatic mechanism date from 1778. Although the automatic design would not succeed until after World War I, when industrialization allowed small automatic wristwatches to be made. The first watchmaker to produce watches of this type was John Harwood whose Swiss-made automatic designs had the capacity to store up to 12 hours of power. Designs that would soon be adopted and improved by legendary companies such as Rolex, with a system of weights that could move more freely and accumulate up to 35 hours of energy, or Eterna with the introduction of bearings to maintain the structural integrity of the mechanism against shocks. or any other type of external force. rolex automatic mechanical watch Currently, most of the mechanical wristwatches that are manufactured use automatic mechanisms and only a few, mainly for collectors, continue to use manual winding. ✚ How does a mechanical watch work? The mechanical watch works thanks to several moving parts that interact in an orderly way inside to move the hands without the need for batteries or electronic components. This mechanism known as movement or caliber works thanks to 5 components, present in all mechanical watches: Main spring: it is the part where the mechanical energy that makes the mechanism work is accumulated. Generally a flat spring with a spiral shape. Balance or balance wheel: it is the part that is in charge of timing. A weighted wheel that sways at a constant pace, thus marking the passage of time. Gear train: it is responsible for transmitting the movement from the main spring to the balance wheel and also for adding each of its oscillations to convert them into hours, minutes and seconds. Keyless work: a set of gears separated from the rest that allow the mainspring to be wound by turning the crown. They are also used to set the clock. Escapement mechanism: its function is to make the gears escape or advance a certain number of times with each swing of the balance wheel. These stops are what produce the characteristic tick-tock of mechanical watches. mechanical movement By turning the crown of the watch, the keyless work winds the mainspring, charging it with mechanical energy, which in turn is transferred by the gear train to the balance wheel. The balance wheel swings at a constant rate and each time it does so it unlocks the lever of the escapement mechanism, which releases a tooth from its gear and causes the hands of the clock to always move at the same speed and in the correct direction. . Additionally, when the escapement gear rotates it again pushes the lever, which in turn strikes the balance wheel and propels it back into motion. In the case of automatic mechanical watches, a system of rotating weights automatically winds the mainspring with each movement of the wrist. Obviously this is a simple description of the operation of a mechanical watch that, in addition to telling the time, can have many other functions called complications, such as a calendar, an alarm or a chronograph, among many others that have been added over centuries of evolution. ✚ The best quality / price mechanical watches In its beginnings, mechanical watches were items that were only available to a few, but today anyone can get a quality watch at a good price. Below are some of the mechanical watches that currently offer the best quality / price ratio: ➤ Seagull 1963 classic Seagull 1963 watch The Seagull 1963 is a classic watch steeped in history, but also a great engineering feat thanks to its intricate column-wheel bi-beat mechanical winding movement. It is nothing less than the first Chinese wristwatch chronograph, manufactured for the country's air forces in the 1960s and reissued today with the same mechanics as before. A very appreciated watch by collectors, especially those who have just started, since it can be obtained at a fairly reasonable price.
