One great piece of invention that looks simple, elegant, but with a lot of complexity, is a watch. Aesthetically designed as a wearable accessory, it takes the right dimension or size of a watch to wear comfortably on a wrist. That is why we often rightfully get too much concerned about the watch dimensions that goes on our wrists. All watches have specific sizes, and no one size is desirable by everyone. If you hear someone is concerned about the watch band size, then technically and aesthetically, it’s all about the watch lug.


What is a watch lug, anyway?

A watch is technically a complex piece of machinery designed to tell time and appeal to our everyday fashion and dressing style. Featuring a watch case and a strap(band), the watch lug is the incredibly sized part of the watch that connects the two.

A watch lug is a projected part of a watch, attached to the watch case and with the help of a metal spring bar(pin), it flexibly holds the watch band. Some people call watch lugs as horns.

The watch lugs are actually an integral part of the watch case, but most often regarded with minimal attention and it is not always or even mentioned in watch specifications. Note that Pocket watches have no watch lugs.

One thing to consider when shopping or choosing a wristwatch is the band size, and a lug width is very crucial to finding the right strap size for your watch that would fit your wrists.

The shape, the style and the design on a watch lug determine the gorgeous appearance, the comfort, and the look and feel of a timepiece. A watch lug width is the most important watch dimension to check, especially when you are looking for the best watches for small wrists.

What is lug width on a watch?

A watch has 4 lugs, a pair is on the case side at 6 O’clock position and another pair is on the case, at the 12′ O’clock position. Lugs all protrude outward along the 6-12 o’clock vertical line, but the lug distance is the length between lugs along a horizontal line (along the 3 to 9 o’clock).

A lug width is the interior space from one lug to another nearest lug. The space between these nearest lugs, allow the watch strap to be fitted to the watch case with the help of spring bars.

This little space,determine the size of the watch bracelet. Watches with larger straps have larger lug width, while timepieces with slim bands have smaller lug distance.

It always suffice to measure and determine the strap size when choosing a watch, and that is when you will notice the importance of lug width. Some watches don’t even have lugs, because they have integrated bracelets that are not removable or interchangeable.

lug width = lug distance = the largest end of a watch band


What is lug-to-lug on a watch?

This is another watch dimension between lugs, but this time, it is measured along the vertical line along a line through 12 to 6 O’clock. Lug to lug distance is sometimes referred to as the length of the case. But it is the length from the tip of one lug at 6 O’clock position to the tip of another lug beyond 12 O’clock position from the tip of one lug to the matching one on the other side of the case, along the vertical line (12 to 6).

As important as the lug width, this lug length is a critical watch measurement that tells how wide your watch case spans across the top or outside part of your wrist. Generally, most watch manufacturers design watches with an average lug width of 20 mm, from 16 mm to 24 mm.

Very particularly for ladies and men with skinny wrists, you can find wrist watches or some vintage timepieces with smaller watch lug to lug measurement. When choosing the best fitting watch bands, you would need to know the exact strap size. It is the lug distance that tells if you watch has very slim or too large watch strap.

How to determine lug width for the right watch band size

A watch lug has a lot of influence on the watch’s aesthetics and knowing how to measure the lug distance is very important to picking the best watch that wears so well on your wrists. Here are simple ways how to determine the actual lug size and the correct strap size of your wristwatch.

Using an old watch trap

If you have had a snug fit watch before, remove the strap and measure the dimensions of the ends. This is one easy way to getting the correct strap size and lug width for your watch. If the old strap is a silicone band, use a ruler or tape to determine the width of the ends.

The size of the largest section of the old band gives you the watch lug width. Some watches have leather straps with printed lug width /strap size values on it.

For example, if the vintage Seiko timepiece comes with a leather strap width of 20mm, then this is equivalent to lug size of 20mm. If you observe carefully, these values may be printed on the straps.

Measure the watch lug directly

If you are buying from a local watch dealer, you may just have to move there, pick up the ideal watch and measure the lug width with a ruler or Digital calipers. This is the right method if no information is printed on the strap to help you determine its size.

You just hold a tape or a ruler and measure the watch dimension yourself and select the right band size for it. Take for example, if TAG Heuer formula 1 has a 21,5mm lug width  on my ruler, then a 22mm band will fit just perfectly in there.

Get it from the manufacturers site online

Go to the website of the manufactures, and check the watch specifications.The manufacturer of the timepiece may offer dimensions and other details including the lug width of your watch. Another online place where to go is the Watch database – WatchBase.
