The sports strap is an adjustable strap made of fluoroelastomer and comes in two sizes to fit smaller and larger Apple Watch models. As this strap has holes for an adjustable fit, all you have to do is make sure that the size range below matches your wrist size. Every Apple Watch comes with a simple sports strap, which can be adapted to any wrist size. However, the world of Apple Watch straps is as diverse as the people who wear them, and if you're looking for a Solo Loop strap or another strap that isn't adjustable, you'll need to know how to use the Apple Watch strap size chart and other metrics to find the right strap.
You can use a band designed for Apple Watch (first generation) or Apple Watch Series 1, 2 and 3 with the Apple Watch Series 4, the Apple Watch Series 5, the Apple Watch SE, the Apple Watch Series 6 and the Apple Watch Series 7, as long as the sizes are compatible. Keep in mind that larger Apple Watches have longer strap options, and smaller watches will offer shorter strap options. I find it absolutely incredible that Apple risks alienating these fans by saying that it will upgrade to Series 7 and its collection of watch straps will be reduced to a single usable strap, the one you get with the new Watch. These lengths can be added to the size of the Apple Watch to approximately equal the circumference of the wrist, plus or minus a few millimeters.
Since the older Series 3 straps fit all Series 6 and SE, Apple Watch fans have a lot of straps. If you're getting ready to buy an Apple Watch, you should consider your wrist size and the available strap options to get the best fit. For the most part, all Apple Watch straps come in a good size range, and you should only pay close attention if your wrist is smaller than average or larger than average. Most straps designed for Apple Watch Series 4, Apple Watch Series 5, Apple Watch SE, Apple Watch Series 6, and Apple Watch Series 7 work with any previous version of Apple Watch.
The 40 mm Sport Loop watch strap can fit wrists from 130 to 200 mm, while the 44 mm watch strap can fit wrists from 140 to 220 mm. For best results, the back of the Apple Watch needs skin contact for functions such as wrist detection, haptic notifications and the heart rate sensor. Made from a stainless steel alloy, the link bracelet is Apple's most expensive strap, with a link design that looks like a high-end watch strap. Wearing your Apple Watch with the right fit, not too tight or too loose and with room for your skin to breathe, you'll feel comfortable and allow the sensors to do their job.
But many of them no longer offer options for 38, 40, 42 and 44 mm size options for all straps. If the band is designed for Apple Watch Series 1, 2 and 3, Apple Watch Series 4 and later, and Apple Watch SE, you can use it. To reiterate, the straps made for the smaller size of the two new sizes work with the older, smaller Apple Watch models and vice versa.
