Understanding how wristwatch sizing works is one of the few things that is quite difficult to understand for those unfamiliar with the subject. If you have ever wondered how watch sizes are measured, today we will explain it in an easy to understand way; so you can get yourself a full size watch.

Let's start by talking a little about how watches are measured to determine their size. Once we understand how they are sized, we'll explain a little bit about how the shape of the case itself can affect how big or how small a watch is perceived on the wrist.

How to measure and size watch cases

Watch cases are measured in millimeters (mm), usually with a measuring tool called a caliper. The most common shape for watch cases is the round case. Round cases are sized by measuring the diameter across the case. Below is a chart that can show the difference between many different sizes. Next, we'll cover how different watch case shapes and sizes compare to each other.

Case Shapes

The cases of these three watches are the same size. However, due to their geometry or design elements such as bezel thickness or dial size, some may actually appear (or "look") either larger or smaller on the wrist.

Compared to a round case, a square case watch has more "space" on the dial due to its geometry. The watch on the right may have the same case size as the round case watch on the far left, with a thicker bezel and/or smaller dial; However, due to the smaller dial size, it looks like a smaller watch, giving the impression that the watch on the left is larger.

In fact,everydesign element in a watch—the type of hour markers, lugs, size and thickness of the hour and minute hands, crown, and pushers—can affect the way case size is perceived.

Case Thickness

The thickness of a case is measured using a caliper from the top center of the watch glass to the middle of the case back. Some watches have ultra-thin cases, while others have bulky case thickness. The more complications a watch has, the thicker the case to accommodate the many components needed to enable additional mechanical functions to work.

Belts and Bracelets

Other things that can affect the way the size of the watch is perceived are the type of strap or metal band, the width of the strap, and whether it has stitching in the same tone or a contrasting tone. Metal bracelets generally appear thicker than leather or fabric (NATO) straps. Straps are usually made to be around 50% of the width of the case; so they look proportionate.

The length of the strap or bracelet is also an important part of sizing a watch.

Smaller watches, up to 36mm, generally look proportionate on a wrist 6" or smaller. Medium watches, 38mm to 42mm, look proportionate on a wrist 6" to 7". Larger watches, 44mm to 46mm, look proportional on a wrist 7" to 8".

Most watch sites, such as PrestigeTime.com, classify the size of their watches by gender. Most commonly as men's watches, women's watches or mid-size watches. Gender-specific sizing aside, this guide is here to help you understand the actual size and perception of the watch, how big or small it looks on the wrist, and what factors contribute to its appearance.
