Find the Right Size Watch Band

Note: A millimeter lug gauge is used in the examples in this instructional. 

         If you use a normal ruler to measure, 1 centimeter (cm) = 10 millimeters (mm).

Step 1: Determining the Type of Band You Need

(1) A "standard" watch band has a straight end that will fit directly in between the watch lugs.

(2) A "stepped" watch band, or an "integrated" watch band, integrates with the watch case. It is a bit wider slightly farther down the band. The widest part doesn't connect to the watch case, it just touches it.

Step 2: Determining the Strap Size

For Watches with "Standard" Watch Bands:

This Band "Lug Width" is 20 mm

Tip: The easiest way to find the size of the watch band you need to replace is to check your old one. It will most likely have the size imprinted on the inside. If it doesn't, just follow the following guidelines:

This Band "Lug Width" is 28 mm

The size band you need is measured as "Lug Size" or "Lug Width," which is the the distance between the lugs of the watch. The lugs are located on both ends of the watch case at the 12:00 and the 6:00 positions.

 

There are two methods to determining what size band you need:  

(1) Measure the width of the end of your old/existing band, where it meets the watch case and fits in-between the watch lugs, in order to determine the "lug width." Your new band should have the same "lug width" as your old band.

This watch case needs a band with a 20 mm "Lug Width"

(2) Measure the distance between the lugs of your watch in order to determine the "lug width" of the band it needs.

 

The width of the watch band ends are equal to the space between the watch lugs.

Both methods work because a band's "lug width" will also be the width of the space between the watch lugs.

 

For Watches with "Stepped" Watch Bands:

Some bands are 'stepped' and are a bit wider slightly farther down the band (away from the watch face). The widest part doesn't connect to the watch case, it just touches it.

 

The size band you need is measured as "Lug Size" or "Lug Width," which is the the distance between the lugs of the watch. The lugs are located on both ends of the watch case at the 12:00 and the 6:00 positions. And for "stepped" bands, you will also need the width of the widest part of the band.

There are two methods to determining what size band you need:

(1) Measure the width of the end of your old/existing band, where it meets the watch case and fits in-between the watch lugs in order to determine it's "lug width." You also want to measure the widest area of the band that will just touch the watch case. Your new band should have the same "lug width" and width at the widest area as your old band.

This Band "Lug Width" is 16 mm
This width of this bands widest point, where it will touch the watch case, is 24 mm

(2) Measure the distance between the lugs of your watch in order to determine the "lug width" of the band it needs. Then measure the distance from the end of one watch lug to the end of the other in order to determine the width the band will need at the widest point that will touch the watch case.

This watch case needs a band with a 16 mm "Lug Width"
This watch needs a band where the widest point that just touches the case is 24 mm

Note: The watch band measured in the first method of "For Watches with "Stepped" Watch Bands" will fit the EBEL watch case measured in the second method.

**A millimeter lug gauge is used in six of the picture examples. It is not needed to measure. A ruler can be used to measure instead. Convert measurements into millimeters.**
