What does the number of jewels in a watch mean, and does it matter for everyday use?
An automatic watch is more than just a style accessory or a way to check the time. It's a precision mechanism that works without a break – every time you move your wrist. However, for it to run smoothly for years, it needs not only good design, but also conscious use and basic knowledge of what happens inside it. One of the most often overlooked, yet crucial elements are the jewels in the watch movement. In this article, you'll learn what their presence means, how they affect the durability of an automatic watch, and how to care for your watch so that it truly serves you for a long time.
Jewels in a watch – what are they for and why do they matter for the durability of the movement?
If you've ever glanced at the specs of your watch and seen information about jewels, you might have considered it a purely technical detail or even a marketing one. In reality, jewels in a watch have a very specific purpose and genuinely affect how long the movement will work without problems. They are not decoration, nor a luxury addition for collectors – they are construction elements that relieve the most sensitive points of the entire system. Without them, metal parts would rub against each other non-stop, leading to accelerated wear, loss of movement stability, and the need for frequent repairs.
In practice, jewels in a watch movement serve as very precise support points. The axes of gear wheels, the balance, and the winding elements rest on them – these are the parts that perform thousands of micro-movements every day. Thanks to this, friction is reduced, the operating temperature is more stable, and the lubricant does not break down as quickly. It may sound like a minor detail, but in mechanical watches, minor details determine years of trouble-free operation.
It's also worth knowing that bearings in watches do not work on their own. Their effectiveness depends on the quality of the movement design, the precision of assembly, and regular servicing. Even the best bearing jewels in a watch won't help if the watch hasn't seen a watchmaker in years or is used under extreme conditions. That's why caring for an automatic watch actually means caring for an entire interconnected system – jewels are one of its foundations, but not the only element worth looking after./Styczeń 2026/ZEGAREK MĘSKI EPOS TIMELESS AUTOMATIC 40mm 3511-152-20-15-30.png)

What does the number of jewels in a watch mean and why doesn't more always mean better? We debunk the watchmaking myth
For years, many manufacturers have accustomed customers to thinking that the number of jewels in a watch is a straightforward quality indicator. The more, the better – it sounds logical, but only at first glance. In reality, the number of jewels speaks primarily about the construction and complexity of the movement, not about whether the watch will be more accurate or durable than another model. A watch with 17 jewels can work just as stably as a construction with 25 or 30 jewels, if it has been well designed and properly used.
Standard manual watch movements have long been based on 17 jewels as a full, functional minimum, which secures the key friction points. In automatic watches, additional elements come into play, such as the rotor, so additional jewels naturally appear. The problem begins when the number of jewels becomes a sales argument rather than a consequence of a real technical need. In such cases, jewels are placed in spots where their presence makes little difference from the user's perspective.
For you, as someone wearing a watch every day, something else matters more. What counts is the quality of execution, a good regulator, sensible lubrication, and regular servicing, not the number itself on the dial or in the description. Of course, a higher number of jewels is not a flaw in itself, but it should not be the main criterion for choosing a watch or a reason for concern if your model has "only" 17 or 21. In practice, the differences in everyday use are minimal, and often imperceptible. A good example are ETA movements, which in classic configurations with a moderate number of jewels have long been regarded as a benchmark of stability, durability, and predictable performance. In practice, the differences in everyday use are minimal, and often imperceptible./Styczeń 2026/ZEGAREK MĘSKI G-GERLACH TATRY 39mm CZARNY.png)

Bearing jewels in a watch and everyday use – what do you actually feel on your wrist?
From the perspective of wearing a watch every day, the topic of jewels might seem abstract, because you don't see their work with the naked eye. And yet, their presence affects several very concrete aspects of use. Above all, it comes down to movement stability over a longer period. A movement in which friction is better controlled de-regulates more slowly and maintains its factory operating parameters for longer.
The matter of servicing is equally important. A watch with a well-designed bearing layout usually requires overhauls less frequently, because the wear of components progresses more slowly. This translates not only into convenience, but also into operating costs over a perspective of several or even a dozen years. Jewels in a watch movement help maintain a balance between precision and durability, which matters especially when you wear the watch regularly, and not just on special occasions.
In everyday use, you'll also appreciate greater resistance to minor overloads and temperature changes. A movement operating on jewels generates less heat and is less susceptible to micro-damage caused by normal wrist movements. This doesn't mean the watch becomes indestructible, but it gives it a clear advantage in the long run, especially if you treat it as a tool rather than a collector's exhibit. A good example of such an approach to durability is the Miyota movement, which, thanks to its simple, well-thought-out construction and sensible use of jewels, is known for its resilience in everyday, intensive use./Styczeń 2026/ZEGAREK MĘSKI TAG HEUER AQUARACER PROFESSIONAL 200 DATE AUTOMATIC 40mm WBP2111-BA0627.png)

How to care for your watch so that the jewels do their job for years?
Awareness of how jewels in a watch work is one thing, but the real difference starts with everyday habits. Even the best bearing jewels in a watch won't fulfill their role if the movement is neglected. Regularity is key – both in wearing and in servicing. An automatic watch that has been lying motionless for months and then suddenly returns to the wrist operates under worse conditions than a watch used consistently.
Equally important is timely servicing, ideally in accordance with the manufacturer's recommendations. During an overhaul, the watchmaker not only cleans the movement but also renews the lubrication at the points where the jewels cooperate with the axes. It is precisely there that the future lifespan of the entire system is decided. Postponing servicing "for later" causes even perfectly designed bearings in watches to start losing their properties. In everyday life, it's also worth avoiding extreme conditions – sudden impacts, strong magnetic fields, or prolonged contact with moisture, if the watch is not designed for it. Taking care of an automatic watch is not excessive caution, but conscious use, which allows the jewels in the watch movement to do exactly what they were created for.
To sum up, the number of jewels in a watch has technical significance, but should not be the main criterion for choosing one. For everyday use, a proven movement, quality of execution, and regular servicing matter more than the number itself in the specs. In the range of our online watch store WestWatches, you'll find models with reliable movements that have been designed with durability, stable operation, and comfort of wear in mind for many years to come.

316L, 904L and surgical steel – what is your watch made of?
Most steel watches, from affordable models to luxury constructions, are made of 316L steel. 904L steel contains more nickel, chromium and molybdenum, and therefore offers higher corrosion resistance, but in itself it does not mean greater scratch resistance. The term “surgical steel”, in turn, does not point to one strictly defined alloy. In watches it most often refers to 316L, but without a specific material designation it may simply be a marketing name. If you are choosing a watch for years, look therefore not only at the words “stainless steel”, but also at the grade of steel, which components are made of the given material and how they are finished.
Japanese or Swiss watches? We compare quality, movements and prices
If you are wondering whether Japanese or Swiss watches are better, the name of the country alone will not give you a good answer. In both cases you will find simple models for relatively little money, solid mid-range automatics and designs belonging to the world's watchmaking high end. Far more about quality will be told to you by the specific movement, the way the case and bracelet are made, the crystal, quality control, accuracy and price. Check how Japanese watches really differ from Swiss ones and what to pay attention to before you choose a model for yourself.
The lifespan of a quartz watch – how long does it really last, and when is it no longer worth repairing?
We value quartz watches above all for their accuracy, convenience and modest day-to-day demands. That does not mean, however, that they can run indefinitely and need nothing more than a new battery once every few years. Over time, the components of the movement itself also wear out, and the moment a watch starts giving trouble can look completely different depending on the model, the way it is used and the availability of parts. So how long can a quartz watch last, what wears out in it most often and when does repair still make sense? Check what its lifespan really depends on.
The second hand on a watch – why does it jump, move smoothly or stop?
The way the seconds hand moves can tell you a lot about a watch's movement, but it is not an infallible test. A single distinct jump per second most often points to quartz, several small movements per second are typical of a mechanical movement, and an almost continuous glide is associated with Spring Drive. There are exceptions, however: there is a quartz watch with a sweeping seconds hand, and a mechanical watch that makes exactly one jump per second. What is more, a stopped hand does not have to mean a fault. Check how to read these signals and when you really need a watchmaker's help.
How do you set an automatic watch? Date, time and time zone 21:00–3:00
An automatic watch does not need a battery, but it does require a little knowledge from its owner. Setting the time or date seems simple, yet the wrong moment or the wrong way of using the crown can affect how the movement works. Many questions concern changing the date at night, moving the hands backwards and restarting a watch after a longer break. Check how to set an automatic watch correctly, what to pay attention to with the crown and why people often talk about particular caution between 9:00 pm and 3:00 am.
Wodoszczelność 10 ATM i 20 ATM – czy możesz pływać i nurkować z takim zegarkiem?
Co naprawdę oznacza 10 ATM lub 20 ATM na zegarku i czy takie oznaczenie pozwala bez obaw wejść do basenu, morza albo nurkować? Same liczby mogą być mylące, dlatego sprawdź, jak czytać klasę wodoszczelności i dobrać zegarek do aktywności w wodzie.
Water resistance 3 ATM – what does it mean and what can you do with it?
3 ATM water resistance means the watch is prepared above all for rain, accidental splashes and brief contact with water during everyday activities. It does not mean that you can swim with it, shower in it or submerge it to a depth of 30 metres. It is precisely the “30 m” marking that most often misleads. It is the result of a pressure test carried out under controlled conditions, not a declared working depth. So if you see 3 ATM, 3 bar or Water Resistant 30 m on the case back or in the specification, treat the watch as resistant to everyday moisture, but not as a watch for water activities.
Rolex-style watches – the best alternatives to the Submariner, Explorer and Datejust
For years Rolex has been one of the most important style benchmarks in the watch world, but its price is not within everyone's reach. That is why it is worth looking at watches similar to Rolex and models inspired by its styling, which offer their own character, solid build quality and much more affordable prices. We are not talking about counterfeits here, but about legitimate watches from other brands that draw on similar solutions and design language. Check out watches inspired by Rolex's style and choose the model that suits your style and budget.
A bronze watch – why does each one change over time?
A bronze watch stands out because its appearance changes along with its owner. The case gradually darkens, turns matte and develops a patina, so two identical models can look completely different after just a few months. This is the greatest advantage of bronze, but also a trait you need to accept before buying. If you expect a watch that keeps its factory shine for years, steel may be a better direction. If, on the other hand, you like vintage looks, signs of use and the natural ageing of a material, bronze gives an effect that is hard to achieve in any other metal.
