What is Lug Width?

Lug width is a measurement between the two lugs of one side. While you are purchasing straps, it is best to check the measurement of watch lugs. After that, you can choose the perfect size straps for your timepiece.

These measurements are in millimeters. It is necessary to take accurate readings because the default of few millimeters in reading can make your straps lose or even not fitting. In other words, because of inaccurate measurements, you cannot find a perfect size strap for your timekeeper.

How to Measure Lug Width?

But, how to measure lug width? Look we want a perfect measurement without any default of even one millimeter. You cannot use a regular scale for lugs measurement. You should use a vernier caliper to measure the width. Let’s check out the steps to measure the lug width.

Step 3: Measure your old straps

If you do not have a vernier caliper then you can measure your old straps with regular scales. And if you have leather straps, then it is too easy to measure because most leather straps come with a printed number for lug width. 

What is Lug to Lug Measurement?

Many people get confused between lug width and lug to lug measurement. Are you one of them? We are here to clear your confusion. The watch lug to lug height is the distance between one side lugs on the case to the opposite side lug on the case.

It is quite complicated to understand these two things. But lug to lug measurement is necessary when you are buying a new watch. With lug to lug height, you should also measure your wrist and case diameter for perfect fitting.

You can measure lug to lug distance and diameter by using a regular scale. To measure wrist size, you can use a measuring tape. It is quite hard to take perfect lug to lug measurement.

But, you can take a measurement that is close enough to perfect size. To get a perfect sized watch, make sure the ratio between lug to lug height and wrist size 0.8 to 0.9 millimeter.

Imagine that your wrist size is 60mm, then the lug to lug height should be 48mm (60 × 0.8) to 54mm (60 × 0.9). After that, you can measure the case diameter. It will help you to find the perfect sized timepiece for you.
