Core principle: Based on the "band width"

In the world of Garmin, the core indicator of watch strap size is its width where it connects to the lugs, usually measured in millimeters (mm), with the most common sizes being 20mm, 22mm, and 26mm .

  • QuickFit® quick-release system : Most Garmin outdoor and sports watches feature the convenient QuickFit quick-release system. No tools are needed; simply snap the buckle to quickly remove and install the band. When shopping, just look for bands marked with the same QuickFit width (e.g., QuickFit 22).

  • Case Size vs. Strap Width : Please note that a watch's "case size" (e.g., 42mm, 47mm) refers to the diameter of the dial and is not equivalent to the strap width. However, a specific case size often corresponds to a fixed strap width. For example, in the Fenix ​​series:

    • The S models (like the Fenix ​​7S) typically have smaller cases (42mm) and corresponding 20mm straps.

    • Standard models (such as the Fenix ​​7) have a medium-sized case (47mm), corresponding to a 22mm strap.

    • The X models (such as the Fenix ​​7X) have the largest case (51mm) and correspond to a 26mm strap.

How do I determine the width of my Garmin watch strap?

There are a few easy ways to find the size you need:

  1. Check the back of your old watch strap : Many genuine Garmin silicone watch straps have the width number printed directly on the inside, such as "22" or "26".

  2. Check the official website : Go to the Garmin website and find your watch model. The supported band widths will be clearly listed on the "Specifications" page. This is the most accurate method.

  3. Manual measurement : Use a ruler or calipers to measure the inside distance between the lugs on your watch to determine the strap width.
