Screw-Down Crown in Watches – What Is It Used For?
At first glance, it's just a small dial on the side of the case. However, in the world of watches, the screw-down crown plays a much bigger role than it might seem. It determines whether your timepiece will survive contact with water, dust, or sudden changes in atmospheric conditions. It is this very element - though often underappreciated - that can determine the durability and reliability of the entire mechanism. If you're thinking about buying a watch that not only looks good but also works flawlessly in all conditions, this element should be at the top of your checklist. In this guide, you'll discover exactly what a screw-down crown is, when it's worth choosing one, and how to care for it so that your watch serves you for many years - without surprises.
What is a screw-down crown in a watch? Check what it can really do and why it's worth taking care of
A screw-down crown is a special type of crown (the dial used to set the time and date) which, after adjustment, needs to be pushed in and screwed in accordance with the thread to fit tightly against the watch case. This way, the mechanism is closed and protected against water, dust, and other contaminants.
Inside the thread of the case and crown, there is a rubber or silicone gasket that further increases water resistance. Such a solution can be found mainly in watches with a water resistance class of 100M (10 ATM) and higher - that is, in models designed for swimming, snorkeling, and even diving.

Why appreciate the screw-down crown? Small element, great protection
Seemingly unassuming, the screw-down crown is one of those watch elements that makes a huge difference - especially when reliability matters. Its main advantage is effective protection of the timepiece's interior against water, moisture, and steam - the biggest enemies of precise mechanisms. Thanks to it, even a technologically advanced watch can safely accompany you by the sea, in the rain, or during training.
But that's not all. The screw-down crown strengthens the winding shaft structure, reducing the risk of accidental damage that can occur with everyday watch wearing. It also makes it easier to operate the watch in less comfortable conditions - e.g., at low temperatures, on a boat, or while traveling. So if you think it's just a decorative detail, it's worth looking at it from a different perspective - as a guardian of your timepiece's durability.
The screw-down crown is often overlooked or underappreciated by users. It allows for winding the watch, as well as setting the current date and time. The crown is an element that can be equipped in both women's and men's watches.

DIY crown replacement step by step - do it right or... don't do it at all
Replacing a watch crown is a task that, at first glance, may seem simple, but in reality requires great precision, a steady hand, and knowledge of the mechanism's structure. The first step is to dismantle the old, worn crown - most often this is done by opening the case back and pressing a special button located near the winding shaft. In some models, it may be necessary to unscrew a small screw above the shaft. Although it sounds like a minor detail, it's easy to make a mistake at this stage that could immobilize the watch or damage the delicate elements inside.
The new crown must be perfectly matched - both to the thread and to the shape and size of the case. If it's too long, it can stick out and catch on clothing; if it's too short, it will make setting the time uncomfortable. Compatibility with the mechanism is also crucial - after installation, the watch should be carefully assembled, all parameters set, and ensure that the structure has maintained its original water resistance. Even if everything works flawlessly, it's worth remembering to regularly replace the gasket - preferably every 2 years. This small procedure can determine whether your timepiece will serve for a decade or end up in a drawer after the first rain.
If the watch crown is installed incorrectly or is damaged, moisture can enter the timepiece, causing damage to the delicate mechanism. That's why the screw-down crown is particularly common in waterproof models. An additional gasket is placed in the case thread, which limits the possibility of water entering the watch. This way, you can use the device in conditions of increased humidity.
How to remove the crown from a watch?
In case you are dealing with a problem such as a broken crown in a watch, exercise particular caution. Typically, to remove the crown, you need to remove the case back and find the winding shaft lock - this may be a small button or screw next to the mechanism. By gently pressing the button (or loosening the screw), you can carefully pull out the crown along with the shaft. However, if the crown has broken off and a fragment is stuck in the thread, DIY repair can be risky - in such a case, it's better to seek a watchmaker's help to avoid damaging the mechanism.
Screw-down crown under control - how not to damage it and enjoy your watch for years
Although the screw-down crown significantly increases the watch's resistance to water and external damage, it also brings greater user responsibility. Its presence makes the watch mechanism more complex and thus susceptible to operational errors. One of the most common is trying to change the time without first unscrewing the crown - this way, it's easy to pull out the thread, tear the gasket, or even permanently damage internal components. Sometimes a moment of inattention is enough to lead to a costly failure.
For this reason, the decision to choose a men's or women's watch with a screw-down crown should go hand in hand with basic knowledge about how it works. Before first use, it's worth spending a few minutes getting acquainted with the manufacturer's instructions - it's a simple investment that will protect you from unnecessary stress and expenses. Remember: the screw-down crown is a great solution, but only when you treat it with due caution.
Does the screw-down crown have disadvantages? What the advertising folder doesn't tell you
Although the screw-down crown is a solution valued for its protective properties, it's not completely without flaws. It requires greater attention and precision from the user - improper handling can lead to mechanism damage. It's enough to try to change the time without first unscrewing the crown to risk pulling it out or tearing the gasket.
Over time, the thread or gasket can wear out, especially if these elements are not regularly cleaned and lubricated. As a result - even though the watch theoretically remains "waterproof" - its real protection against moisture can significantly decrease.
That's why knowledge of crown operation principles is so important. Before you start using it, check the instruction manual or consult a watchmaker. This small detail, if used incorrectly, can determine the fate of your watch - even one from the top shelf.
