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.

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.

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

The beads of rice (sometimes called a grains of rice bracelet) is one of those quintessential watch accessories that belongs in every collection. Once made by Jacoby-Bender in the mid-twentieth century, the beads of rice style bracelet was provided with some of the most storied watches of all time (stainless steel Patek Philippe chronographs come to mind), and for good reason. The bracelet exudes a subtle elegance that completely transforms the look and feel of your watch over a more typical leather strap. While it's great with virtually any vintage watch, the beads of rice works equally well with contemporary dress (or cross-over dressy/sporty) watches.

Details and Finish

The Forstner Beads of Rice bracelet recreates the look of the vintage JB beads of rice, with some key updates. The bracelet is beautifully finished in alternating polished and brushed stainless steel -- a finish that flows from the clasp, to the beads, and the end piece itself.

Construction and Adjustment

Solid 316L stainless steel (links are 3mm thick) with removable links (via single screw system). The length may also be adjusted in micro-increments via the clasp. The bracelet fits wrists ranging in size from approximately 5-8 inches in circumference.

Sizes

The Forstner Beads of Rice Bracelet is offered in five different end piece widths--16mm, 17mm, 18mm, 19mm, and 20mm. The central "beads" portion is 18mm for all sizes. Please note that the end piece is fixed, and not removable.

Included

Spring bars, screwdriver for size adjustment.
