Mechanical Watch

The Movement

The movement, often referred to as the ‘calibre’, is the heart of the watch. It is the complex mechanism that powers the watch and keeps time. Movements in luxury mechanical watches are typically either manual or automatic, both of which have their unique characteristics and appeal.

Manual movements require the wearer to manually wind the watch, usually by turning the crown, to store potential energy in the mainspring. This energy is then gradually released to power the watch. The art of winding a watch is often seen as a ritual that connects the wearer to the timepiece.

Automatic Movement

Automatic movements, on the other hand, harness the energy from the wearer’s wrist movements to wind the mainspring. This is achieved through a rotating weight, known as the rotor, which moves back and forth with each motion of the wrist. The convenience of not having to manually wind the watch has made automatic movements popular among many watch enthusiasts.

Despite the differences, both manual and automatic movements are admired for their intricate assembly of gears, springs, and wheels. The beauty of these movements is often showcased through a transparent case back, allowing the wearer to appreciate the mechanical ballet that keeps the watch ticking.


Complications refer to any function on a watch beyond the simple display of hours, minutes, and seconds. These can range from the practical, like date displays and chronographs, to the highly complex and prestigious, such as perpetual calendars and minute repeaters.

Complications are a testament to the watchmaker’s skill and creativity. They add layers of complexity to the movement and are often the defining features of a luxury mechanical watch. The more complications a watch has, the more valuable and coveted it becomes.

The Case

The case houses the watch movement and provides protection from dust, moisture, and shocks. It is also a major factor in the watch’s aesthetics, contributing to its overall design and style. Cases can be made from a variety of materials, with stainless steel, gold, and platinum being the most common in luxury mechanical watches.

The shape of the case can also vary, with round cases being the most traditional and common, while square, rectangular, and tonneau (barrel-shaped) cases offer a more distinctive look. The case size, measured in millimeters across the diameter, is another important aspect to consider as it affects both the wearability and the presence of the watch on the wrist.

Case Back

The case back is the rear part of the watch case, which can either be solid or transparent. A solid case back is typically engraved with information about the watch, such as the brand, model, and serial number. Some luxury watch brands also use the case back as a canvas for intricate engravings or decorations.

Transparent case backs, made from sapphire crystal, allow the wearer to view the movement in action. This is a popular feature in luxury mechanical watches, as it showcases the intricate craftsmanship and beauty of the movement.

Water Resistance

Water resistance is a measure of how well a watch is sealed against the ingress of water. It is typically indicated in meters, but it does not imply that the watch can be taken to that depth. Instead, it represents the pressure the watch can withstand, which is tested in a laboratory setting.

While most luxury mechanical watches offer some degree of water resistance, it’s important to note that this resistance can decrease over time due to wear and tear. Regular maintenance and pressure testing are necessary to ensure the watch remains water-resistant.

The Dial

The dial, or face of the watch, is where time is displayed. It is one of the most visible parts of the watch and plays a significant role in its aesthetic appeal. The design, color, and layout of the dial can greatly influence the overall look and readability of the watch.

Elements on the dial such as the hour markers, hands, and logo are often meticulously crafted and applied by hand. Some luxury watches also feature intricate dial designs or decorations, such as guilloché patterns or enamel painting, which add to their uniqueness and value.


The hands are the moving parts that indicate the hours, minutes, and sometimes seconds on the dial. They come in various shapes and styles, and their design can significantly impact the readability and aesthetic of the watch. In luxury mechanical watches, the hands are often made from metal and may be polished, brushed, or even coated with luminescent material for visibility in low light.

The seconds hand, if present, can either be central (moving around the entire dial) or subdial (located in a smaller dial on the main dial). The latter is often found in watches with a small seconds complication, which adds a layer of complexity and elegance to the dial layout.


Indices are the markers on the dial that indicate the hours. They can be represented in various forms, including Arabic or Roman numerals, simple lines or dots, or even precious stones in some luxury watches. The design and placement of indices can greatly influence the overall style and readability of the watch.

In addition to the hour indices, some watches also feature minute markers around the outer edge of the dial. These can be particularly useful in chronograph watches, where precise timing is key.

The Strap or Bracelet

The strap or bracelet is what secures the watch to the wrist. While its primary function is practical, it also plays a significant role in the overall aesthetic and comfort of the watch. Straps can be made from a variety of materials, including leather, rubber, or fabric, while bracelets are typically made from metal links.

The choice between a strap or bracelet often comes down to personal preference and the intended use of the watch. A leather strap, for example, can give a watch a classic and elegant look, making it suitable for formal occasions. A metal bracelet, on the other hand, can be more durable and water-resistant, making it a good choice for sporty or dive watches.

Leather Straps

Leather straps are a popular choice for luxury mechanical watches due to their comfort and classic appeal. They can be made from various types of leather, including calf, alligator, and ostrich, each offering a distinct look and feel. The quality of the leather and the craftsmanship of the strap can greatly influence the comfort and longevity of the strap.

Over time, a leather strap will conform to the wearer’s wrist, creating a personalized fit. However, it’s important to note that leather straps are not suitable for water activities and require care to maintain their appearance and condition.

Metal Bracelets

Metal bracelets are made from links of metal that are connected together, allowing for flexibility and comfort. The most common metals used in luxury watch bracelets are stainless steel, gold, and titanium. Each material has its own characteristics and advantages, such as the durability of steel, the prestige of gold, or the lightweight nature of titanium.

A well-made metal bracelet can last a lifetime if properly cared for. It can also be adjusted for a perfect fit by adding or removing links. Unlike leather straps, metal bracelets are suitable for water activities and are generally more resistant to wear and tear.


Understanding the various components of a luxury mechanical watch can enhance one’s appreciation for these horological masterpieces. From the intricate mechanics of the movement to the craftsmanship of the case and dial, each part contributes to the overall function, aesthetics, and value of the watch.

Whether you’re a seasoned watch collector or a novice enthusiast, we hope this glossary has provided you with a deeper insight into the fascinating world of luxury mechanical watches. Remember, a watch is not just a timekeeping tool, but a piece of art, a symbol of personal style, and a testament to human ingenuity and craftsmanship.
