Finding your Strap Width

How to Find Your Strap Size

Not sure what size strap you need? There are three ways to find out - pick whichever is easiest for you.


1
Quickest method

Check the Back of Your Strap

The fastest way is to flip over your existing strap and look for a number printed or stamped on the back. A number like 22 means your watch takes a 22mm strap - that's all you need to know.

Strap size printed on the back of a watch strap

Most smartwatches will show 18, 20, or 22 on the back of the strap or on the underside of the watch itself. The number refers to the strap width - how wide the strap is where it attaches to the watch - not the overall length of the strap.

Can't find a number? If there's nothing printed on your strap, use Method 2 below to measure it directly - it only takes a minute.

Most accurate method

Measure the Lug Width

The lug width is the distance between the two metal prongs (lugs) on one end of your watch case - this is exactly where the strap attaches, and it's the same as the strap width you need to order.

Diagram showing the four lugs on a watch and where to measure

Your watch has four lugs - two at the top and two at the bottom. Measure between the two lugs on either end (the red line in the diagram above). Both ends will give the same measurement.

  • Lay your watch face-up on a flat surface.
  • Place a ruler or tape measure across the top set of lugs.
  • Measure the gap between the inner edges of the two lugs.
  • That number (in mm) is your strap size.
Ruler measuring lug width on a watch Two ways to measure watch lug width - ruler and tape measure both showing 22mm

Both measuring methods in the image above give 22mm - so this watch takes a 22mm strap.

Avoid phone camera rulers Camera-based measurement apps are often inaccurate enough to give you the wrong size. A 1mm error is all it takes for a strap not to fit - use a physical ruler or tape measure instead.
Why our straps measure slightly under size Our 22mm straps actually measure around 21.95mm - this is intentional so the strap slides cleanly into your 22mm lugs. This is standard across the industry.

If you're still unsure, you can also measure the top of your existing strap where it meets the watch (marked A in the diagram below). Don't measure further down - straps taper as they get longer, so you'll get a smaller number than you need.

No ruler needed

Look It Up on Google

For popular watch brands and models, you can often find the lug width with a quick Google search. This works well if you know your exact model name or number - manufacturers sometimes change strap sizes between models, so the more specific you can be, the better.

Search for:

[Brand] [Year] [Model Name/Number] lug width

For example:

Rolex 2016 Submariner 114060 lug width
Daniel Wellington 2019 Cornwall lug width
Example of a Google search result showing lug width for a watch model

If the lug width search returns nothing, try replacing "lug width" with strap width - both terms are used interchangeably.

Got an odd-numbered result? If Google returns a 21mm lug width, a 20mm strap will still fit - there'll be a small 0.5mm gap on each side. You'll also need to reuse your original spring bar for the strap to attach correctly.

The Story

Forstner, in the 1940s, created a series of Bamboo- or Bonklip-style watch bracelets. These stainless steel watch bands, with their ladder design, had many of the same features that popularized the Komfit with NASA astronauts. They were adjustable, having the ability to be sized in increments of about 3mm, fit a wide variety of wrist sizes, and, of course, were extremely comfortable. The bracelets also could be worn with watches having fixed (non-removable) lug bars. As a result, the Bamboo- or Bonklip-style bracelets were often provided with military-supplied watches (for example, the "Bonklip" (English made) bracelet was supplied with the IWC Mark XI) which often had such fixed bars. Forstner created a version, however, that improved on prior designs, with a spring-loaded clasp that made the wearing experience more intuitive yet still secure. This feature is included on the current reissue.

Details and Finish

The Forstner Klip brings back one of the most popular bands in Forstner's historic catalog. The present bonklip-style bracelet has an 18mm wide central portion, with alternating brushed and polished finishes on the rectangular "ladder" design, and a polished spring-loaded clasp. Made entirely of stainless steel, the band is light, breathable, and extremely comfortable, having the ability to be easily sized in approximately 3mm increments for the perfect fit.

Length and Width

Adjustable between 115mm and 230mm (fits wrists ranging from approximately 6 inches to 8 inches). The central "ladder" portion is 18mm wide for all variants.

End Piece/Fixed Lug Bars

End pieces are fixed design, and offered in sizes 18mm, 19mm, 20mm, 21mm, and 22mm. The end piece fits fixed lug bars up to 1.5mm thick (there is a 1.5mm slit behind the lug piece that clips over such fixed bars).

Width

The central "ladder" portion is 18mm wide for all variants.
