13 Different Parts of a Watch: A Beginner’s Guide

Watches are timeless accessories that have been around for centuries, serving as both functional timekeepers and fashionable accessories. While watches may seem simple at first glance, they are actually complex mechanical devices made up of many intricate parts that work together to tell time. Understanding the different parts of a watch can help you make an informed decision when purchasing one, as well as provide a deeper appreciation for the timepiece itself. This beginner’s guide will break down the key components of a watch, from the face and hands to the movement and crown. 

Parts of a watch

Let’s start with the watch case.

1. Watch Case

The watch case is the outer shell of a watch that protects its internal components, including the movement and dial. It is the main component that gives a watch its style and shape, and it is often made of a variety of materials, including stainless steel, titanium, gold, and others.

The watch case serves as the foundation for the watch, holding all of its other parts in place, and it also provides a water-resistant barrier that helps to keep the watch protected. The watch case is available in a range of sizes, shapes, and styles, and it is one of the key elements that determine the overall look and feel of a watch.

Note: In previous blog post, we covered the various forms and shapes. For a deeper understanding of the watch case, be sure to check it out. 

2. Watch Bezel

The watch bezel is the ring surrounding the dial of a watch, serving to protect the crystal and hold it in place. It also often features markings for measuring elapsed time, or decorative embellishments to enhance the appearance of the watch.

3. Watch Crown

The crown of a watch is a small button located on the side of the case and serves as a means of adjusting the time and date on the watch. It can also be used for winding the watch if it is a manual-winding mechanism. The crown is an essential part of a watch and its design and function can vary depending on the type of watch and its intended use.

Some crowns are screw-down, meaning they screw into the case to create a water-resistant seal, while others are push-pull, which are simply pulled out to adjust the time and date. The shape and size of the crown can also vary and can be an important factor in the overall style and look of a watch.

4. Watch Lugs

Lugs are the metal extensions on the top and bottom of a watch case that serve as attachment points for the watch strap or bracelet. They are important parts of a watch as they not only hold the strap in place but also help to secure the watch to the wrist.

There are different styles of lugs, including curved, angled, and straight, and each style can affect the overall look and comfort of the watch. 

5. Watch Dial

The watch dial is the face of a timepiece that displays the time and any additional functions. It is often the most visible part of a watch and contributes greatly to its overall appearance. The design, color, and material of the dial can vary greatly, giving each watch its unique personality and style. The dial also holds the hands, markers, and any other indicator that displays the time.

6. Watch Subdials

Subdials, also known as small dials or complication dials, are an additional feature often found on watch faces. These smaller dials can display information such as the seconds, chronograph readings, or even the date. They add a level of complexity and style to a watch, making it stand out and attract attention.

Some watches even have multiple subdials, which can be used to display a variety of information all at once. The inclusion of subdials allows for added functionality in a watch, making it more versatile and useful for a range of activities.

7. Watch Hands

The watch hands, also known as the pointers, play an important role in telling time. There are three main types of watch hands: hour, minute, and second hands. The hour hand points to the hour markers on the dial, the minute hand points to the minute markers, and the second-hand points to the second markers.

The shape, color, and size of the hands vary among different watch designs, giving each watch its unique appearance. Some watches may also have additional hands for additional functions, such as a chronograph or a GMT function. The watch hands must be precisely aligned with the markers and powered by the watch’s movement to accurately tell time.

Note: we recently published a comprehensive guide on the 15 styles of watch hands. Check it out to learn more about this topic.

8. Day & Date Windows

The day and date window on a watch is a feature that displays the current day of the week and date. This feature can be found on many quartz and mechanical watches and is usually located at the 3 o’clock or 6 o’clock position on the dial.

Some watches have a quickset day and date feature, allowing the user to easily change the date by pulling out the crown and turning it. The day and date window is a convenient and practical feature, especially for those who need to keep track of both the time and the date.

Note: Some timepieces display only the date, while others feature both the date and day.

9. Watch Crystal or Glass

The watch crystal or glass refers to the clear cover over the dial of a watch. It serves as protection for the watch’s delicate components, while also allowing the wearer to view the time easily.

The material of the crystal can vary, with common options being mineral glass, sapphire crystal, and acrylic. The type of crystal used often affects the durability and scratch resistance of a watch.

Watch straps & bracelets are an integral part of a watch and are responsible for securing the timepiece to the wrist. They come in a variety of materials including leather, metal, fabric, and rubber, allowing for personalization and style options.

13. Watch Movement 

The watch movement is the engine that powers a timepiece and is the heart of a watch. It is responsible for keeping accurate time and is the driving force behind a watch’s functions.

There are two main types of watch movements: mechanical and quartz. Mechanical movements use a mainspring that is wound by hand or by an automatic winding mechanism, while quartz movements use a battery to power a quartz crystal that vibrates at a very precise frequency. The movement type affects the accuracy, maintenance, and cost of the watch, and is an important factor to consider when choosing a watch.
