Sizing at a Glance

Before purchasing a watch, it’s crucial to determine the size of its two main parts. First, the case housing the face and components. Second, the band securing the watch to your wrist. For accurate measurements, you’ll need a vernier caliper and record the dimensions in millimeters.

Choosing the Right Case Size

To find the perfect case size for you, consider both the case diameter/width, and the case thickness. The watch case should ideally be proportionate to the size of your wrist. If you often wear dress shirts, a watch with a thinner case is preferable. Personal preference also plays a significant role in your choice of case diameter and thickness.

Determining Band Width and Length

The watch band’s width and length are equally important factors. Generally, the band width is about 50% of the case diameter, but personal preference should be your primary consideration. To measure the strap length of your wristwatch, use a measuring tape to determine your wrist’s circumference in inches. Then, refer to the watch size chart provided below to find the appropriate strap length.

Strap Length Representation

The strap length of a wristwatch is usually presented as X/Y mm (e.g., 120/70. The first number (X) indicated the length of the long end in millimeters, while the second number (Y) represents the buckle end in millimeters.
