TLDR: Make sure the strap you buy is a quick release strap for a smart watch. Find your smart watch below.
For smartwatches, ensure you purchase a Quick Release or two piece strap to ensure it doesn't cover your heart rate sensors.
A two piece strap is literally just that... it has two pieces and attaches to each end of the watch.
A single piece strap will travel underneath the watch which will block heart rate sensors. If you don't care about your heart rate, you can most definitely use these as well.
Be sure not to confuse the strap width with strap length.
Finding your strap size can be quite confusing so we've dumbed it down to make it super easy for you.
Method 1: Smartwatches:
Smartwatches are usually the easiest to find as they will have a number on the back of your strap to tell you what size strap it uses.
The strap width refers to the size that fits your watch and NOT the length of the strap. For common smartwatches, the easiest way to check is by flipping your watch.
Most smartwatches should say 18, 20 or 22 on the back. For example, if the back says 20, this means you will need a 20mm strap! It's that easy!
If your watch does not have this, you may need to use the links below to find the correct size.
Method 2: Using a Ruler *Recommended*
The easiest and most accurate way to find your strap size is to use a ruler and measure between the lugs. This is known as the lug width. This is also the same as the strap width.
The lugs are the pointy ends of your watch which hold the strap onto the watch.
As you can see, we've measured this two ways, the top measuring device shows 22mm, but also, the bottom tape measure measures 22mm.
This means in our store, you would select a 22mm strap! That's it!
We do NOT recommend using camera ruler apps on your phone to measure. These can be inaccurate as a 1mm difference is enough for the strap to not fit to your watch.
PS: Our straps will measure slightly narrower than 22mm so that it fits to your watch! This means our straps will actually measure 21.9mm to fit your 22mm lugs.
If the concept of lug width is too confusing, you can see in the diagram below, the lug width and strap width of A are the same. This means, you can also measure the top of the strap where the A is marked. Do not measure anywhere else along the strap as you can see it tapers (narrows) as you get lower on the strap.
Method 3: The Lazy Method:
What you will need:
- Your watch brand
- Your watch model number, year, name (model numbers are ideal because a manufacturer may change the size between different model numbers)
What you need to know:
This method works best for the more 'popular' brands/models. If you don't have the exact specifics of the watch - do not use this method.
Go to Google and in the search field, type the following:
(BRAND) (YEAR / MODEL NAME/NUMBER) Lug Width
Rolex 2016 Submariner 114060 Lug Width
Daniel Wellington 2019 Cornwall lug width
You will be able to find different websites which will state the lug width of the watch you are looking for. Here's an example of what to look for:
Note: if you have an odd numbered strap size, for example, a 21mm lug width, you can use a 20mm strap on your watch. This will mean there will be a 1mm gap however.
If no results come up, you can also use the same search terms but changing lug width to strap width
Rolex 2016 Submariner 114060 Strap Width
Daniel Wellington 2019 Cornwall Strap Width
