Apple Watch Series 4, Series 5, and Series 6 come in 40mm and 44mm case sizes, so they're the same. As long as you get the same size for the new Apple Watch, the existing bands should fit seamlessly. Like the Series 7 and Watch SE models, you can purchase an additional sports band, Solo Loop strap, or a different band separately. With the Apple Watch coming in so many different case sizes, it's no wonder people get confused as to which of the different watch bands will fit the watch they have.
More than a year ago, Apple announced plans to search for child sexual abuse material (CSAM) with the release of iOS 15.2.However, even though Apple Watch Series 4, 5 and the new Apple Watch Series 6 come in slightly different case sizes of 40mm or 44mm, your old bands from Series 3 and earlier will still fit. The always-on display of the Series 7 is lost, as well as the blood oxygen monitoring and the electric heart rate sensor for performing an ECG, and there are not as many finishing options as the models in the series 7 to 14 instead of 23, but otherwise, the Watch SE is a feature-packed smartwatch. However, Max Weinbach has now said on Twitter that the new Apple Watch straps “will not be compatible with old watches. As was the case when the Apple Watch Series 4 was introduced with larger sizes, Apple's new straps are labeled to match the Series 7.For the 40mm and 41mm Apple Watch models, you can get individual loop bands in the size range of one to nine, while the 44mm and 45mm models work with band sizes four to 12.Apple Watch Series 3 offers an S3 processor, along with built-in GPS, a waterproof body and a barometric altimeter, all of which were added over the previous Series 1 model.
The Sport Loop band is made of woven nylon with dense loops on the skin side to cushion and allow moisture to escape. With three ranges, GPS and GPS and Cellular models, two different sizes, plus all the straps that can be mixed and matched, as well as the additional Nike, Hermès and Watch Edition models, choosing the right Apple Watch for you is more complicated than it seems at first glance. Apple Watch Series 7 is expected to be announced at Apple's September event (yet to be announced), although rumors suggest that shipments will be delayed. Apple Watch Edition models are only available for Series 7 models and offer the same features and specifications as Series 7 but in a different case.
Two colors are available for the 38mm and 42mm watches, although it also works with the Series 7 and Watch SE models. It's hard to say what exactly Apple will do, so we'll probably have to wait until the new straps hit stores to find out if they're interchangeable or not. The Apple Watch Series 7 didn't receive the expected flat-edge redesign, but it will come with a larger body.
