The Function of the Crown

The crown, often located on the right side of the watch case, is a knob-like component used for setting the time and date on a mechanical watch. It’s also used to wind the watch’s mainspring, providing the energy needed for the watch to keep time accurately.

When you pull out the crown, you engage the setting mechanism of the watch, allowing you to adjust the hands or the date display. Pushing the crown back in disengages the setting mechanism and allows the watch to resume its normal operation.

Winding the Watch

For manual wind watches, the crown is used to wind the mainspring. This is done by turning the crown, typically in a clockwise direction. The energy stored in the mainspring is what powers the watch.

Automatic watches, on the other hand, are wound by the motion of the wearer’s wrist. However, they can also be manually wound via the crown, which is useful if the watch hasn’t been worn for a while and needs a power boost.

Setting the Time and Date

The crown is also used to set the time and date on a watch. By pulling the crown out to its second position, you can adjust the position of the hour and minute hands. If your watch features a date function, pulling the crown out to its first position allows you to change the date.

It’s important to note that not all watches have the same crown positions. Some luxury watches may have additional crown positions for setting other complications, such as a moon phase or a second time zone.

Types of Crowns

While all crowns serve the same basic functions, there are several different types of crowns, each with its own unique design and features. The type of crown used can greatly affect the watch’s aesthetics, usability, and water resistance.

Some of the most common types of crowns include the push-in crown, the screw-down crown, and the onion crown. Each of these crowns has its own unique characteristics and uses, which we’ll explore in the following sections.

Push-In Crown

The push-in crown is the simplest and most common type of crown. As the name suggests, it’s simply pushed in to engage the watch’s winding mechanism. To set the time or date, the crown is pulled out to its respective position.

Push-in crowns are easy to use and relatively inexpensive to produce, making them a popular choice for many watch manufacturers. However, they don’t provide as much water resistance as other types of crowns, making them less suitable for dive watches or other water-resistant timepieces.

Screw-Down Crown

The screw-down crown is a type of crown that’s designed to provide enhanced water resistance. It works by screwing down onto the watch case, creating a seal that prevents water from entering the watch.

Screw-down crowns are commonly found on dive watches and other timepieces designed for water activities. They’re a bit more complex to use than push-in crowns, as they need to be unscrewed before they can be pulled out for setting the time or winding the watch. However, their superior water resistance makes them a worthwhile feature for anyone who spends a lot of time in or around water.

Onion Crown

The onion crown is a type of crown that’s characterized by its large, bulbous shape, which resembles an onion. This design makes the crown easier to grip and operate, especially for pilots or divers who may be wearing gloves.

Onion crowns are often found on pilot’s watches and other timepieces designed for rugged use. They add a distinctive aesthetic to the watch, and their larger size can make the watch more comfortable to operate.

The Crown’s Role in Watch Aesthetics

While the crown’s primary function is utilitarian, it also plays a significant role in the overall aesthetics of a watch. The size, shape, and design of the crown can greatly influence the look and feel of the timepiece.

Some luxury watch brands use the crown as a canvas for their logo or emblem, adding a touch of branding to the watch. Others may use the crown to add a pop of color or a unique design element to the watch. Regardless of the approach, the crown is a key component of a watch’s visual identity.

Crown Design and Brand Identity

Many luxury watch brands use the crown as a way to express their brand identity. For example, Rolex is known for its distinctive crown logo, which is often engraved on the crown of their watches. Similarly, Patek Philippe uses a Calatrava cross on their crowns, a symbol that’s closely associated with the brand.

These branded crowns serve as a subtle yet powerful way for watchmakers to stamp their identity on their timepieces. They’re a testament to the attention to detail that goes into every luxury watch, and they add an extra layer of exclusivity and prestige to the watch.

Crown Materials and Finishes

The material and finish of the crown can also contribute to the watch’s aesthetics. Most crowns are made from the same material as the watch case, such as stainless steel, gold, or titanium. However, some watchmakers use different materials for the crown to create a contrast or add a unique touch.

For example, a watch with a stainless steel case may feature a crown made of gold or set with a precious gemstone. Similarly, a watch with a polished case may have a crown with a brushed or satin finish. These variations in material and finish can add depth and interest to the watch’s design.

The Crown’s Impact on Usability

While the crown’s design and aesthetics are important, its impact on the usability of the watch is equally crucial. The size, shape, and placement of the crown can greatly affect how easy it is to operate the watch.

A well-designed crown should be easy to grip and turn, even for those with larger fingers or those wearing gloves. It should also be positioned in a way that doesn’t dig into the wearer’s wrist or interfere with wrist movement.

Crown Size and Shape

The size and shape of the crown can greatly affect its usability. A larger crown is generally easier to grip and turn, making it more user-friendly. However, if the crown is too large, it can dig into the wearer’s wrist or interfere with wrist movement.

Similarly, the shape of the crown can affect its usability. A crown with a fluted or ridged edge is easier to grip than a smooth crown. Some crowns also feature a recessed design, where the crown is partially embedded into the watch case, making it less likely to snag on clothing or other objects.

Crown Placement

The placement of the crown can also impact the watch’s usability. Most watches have the crown on the right side of the case, which is convenient for right-handed users. However, some watches, known as “destro” or left-handed watches, have the crown on the left side of the case.

Some watches also feature a crown guard, a protective feature that surrounds the crown to prevent it from being accidentally knocked or damaged. While a crown guard can add bulk to the watch, it can also enhance the watch’s durability and longevity.


The crown may seem like a small and insignificant part of a luxury mechanical watch, but as we’ve seen, it plays a crucial role in both the operation and aesthetics of the timepiece. From winding the watch and setting the time, to enhancing the watch’s visual appeal and usability, the crown is a testament to the craftsmanship and engineering that goes into every luxury watch.

So the next time you glance at your watch to check the time, take a moment to appreciate the humble crown. It’s not just a knob on the side of your watch, but a vital component that keeps your timepiece ticking accurately and beautifully.
