Parts of a Watch and Functions

Bezel

The bezel is the outer ring that surrounds the watch. It is simple, decorative, or functional, and generally, its material is metal.

Case

It is the housing for the inner working parts of the watch. Depending upon the type and design, this case can be made of metal, plastic, or ceramic.

In the collection of some premium watches, this case can be silver, gold, or sometimes platinum. It serves as a protection unit for all inner parts and protects from wear and tear.

Crown

The crown is a little button on the right-hand side of the dial. Its function is to change the time according to need. It has some knurling on the face, which gives us some grip for altering the time.

While setting the right time, we have to pull the crown and rotate it according to our requirements by pushing it within the body.

Crystal

The crystal is the transparent cover placed on the top of the dial. The function of the crystal is to protect the dial and hands from dust and dirt. The crystal is made of plastic, glass, or synthetic sapphire.

These are not real crystals. Synthetic sapphire is mostly used in crystals because it is durable and scratch-resistant.

Dial

The dial is the part of the watch that displays the time. In a digital watch, the dial has a numerical display. However, in the analog watch, the dial consists of an hour hand and a minute hand, which dials the timing.

It gives a good aesthetic look to the watch. It has different colors, textures, and materials. The dial consists of an hour marker in Arabic or Roman numeric placed on the circumference.

Hand

Hands are the thin metal strip that moves with the dial to indicate the time. Generally, there are hours, minutes, and secondhand. The hour hand and the minute hand are thicker than the second hand.

But the hour hand is shorter in length rather than the second and minute hand. These hands have some design that improves the entire aesthetic of the watch.

In digital watches, there are no hands. All the timing is displayed in digital format.

Hour Marker

This hour marker is the label within the dial, which ranges from 1 to 12 indexes and indicates the actual time. Arabic numerals and Roman numerals are the most common types of hour markers.

Arabic Numerical
It is the 1-12 numbers that appear on the dial. Depending upon the type and design of watches, it can be 1 to 12, 12 and 6, 3,6,9,12, or simply 12.
Roman Numerical
Roman numerals are the I, II, III up to XII that appear on the dial. This type of Roman numerical marking is phasing out and is found in vintage watches.

Lugs

Lugs are the small metal attachment on both sides of the bezel at 6 and 12 o’clock. It has two holes inside, which can be used to attach the strap.

The function of lugs is to connect the strap to the watch using metal spring bars. Depending upon the type and brand of watches, lugs can be decorative or simple.

A vernier caliper is used to measure the distance between two consecutive lugs. Generally, this length lies between 18 to 24 mm.

Pusher

The pusher is a button near the crown, and it looks like the crown. The function of the pusher is to change the date or stop and start the chronograph. Depending upon the type and brand of watches, a pusher can be one more.

Subdial

The Subdial is a smaller dial placed within the main dial. Its function is to display dates, seconds, or chronographs. It can be one or more depending upon the type of watch.

Strap/Band

The function of the strap is to secure the watch over the wrist. Various strip designs are available on the market, and they are made of different materials, such as rubber, leather, nylon, or stainless steel.

This strap is attached to the lugs on both sides using a metal spring bar.
