Watch Lug Database

Watch lug sizes refer to the width of the space between the lugs (the protruding parts of the watch case that hold the strap or bracelet in place). A simple illustration below shows the distance between the watch lug also known as "lug width".

This measurement is crucial for selecting a compatible watch strap or bracelet.

 

Here are some key points about watch lug sizes:

Measurement:
- Lug size is measured in millimeters (mm).
- Common sizes include 18mm, 20mm, 22mm, and 24mm, though there are many other sizes available.

Importance
- The lug width ensures that the watch strap or bracelet fits snugly and securely between the lugs.
- A mismatched lug width can result in an ill-fitting strap, compromising both aesthetics and comfort.

Variety
- Straps come in various materials, such as leather, silicone, metal, and nylon, and should match the lug width for proper fit.
- Some watches feature quick-release spring bars, making it easier to change straps without special tools.

Compatibility
- When purchasing a new strap, always check the lug size of your watch.
- Many strap retailers provide detailed size charts and compatibility information to help buyers select the right strap.
