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. Of course, as always, you'll need the right strap size for the right watch size. Older bands that fit the 40mm Apple Watch Series 6 will fit Series 7, and the 44mm straps will fit the new 45mm size.
Remember that since all bands will be compatible with the new Apple Watch, there is no reason to wait for the launch of Apple Watch Series 7 to buy new bands if you're looking for a new look. However, just like all previous bands fit the Apple Watch Series 7, these 41mm and 45mm straps are compatible with previous watches. Since the older Series 3 bands fit all Series 6 and SE, Apple Watch fans have plenty of straps. After all, personalization was one of the elements that Apple touted when it launched the Watch.
All watch bands are compatible with all Watch series and editions. The size and shape of the connector are the same on all Apple Watches. The 38mm straps fit 40mm watches. Luckily, Apple has stated that all of the above bands will work with the Apple Watch Series 7, so you don't need to replace all of your best Apple Watch bands if you plan to buy the newest Apple Watch.
Recall that only four versions of the Apple Watch have the current dimensions, Series 4, Series 5, Series 6 and SE. As was the case when the Apple Watch Series 4 was introduced with larger sizes, Apple's new bands are labeled to match the Series 7.Weinbach's information that the new Apple Watch “will use different straps that won't be compatible with old watches” is open to interpretation, at best. Apple Watch Series 7 has approximately 20% more screen area than last year's Series 6, and the bezels are 40% thinner. Apple completely redesigned the Apple Watch Series 7 screen to create more than 50% more screen area than Series 3 and 20% more screen area than Series 6.Wearing your Apple Watch with the right fit, not too tight, not too loose and with room for your skin to breathe keeps you comfortable and allows the sensors to do their job.
More than a year ago, Apple announced plans to search for child sexual abuse material (CSAM) with the release of iOS 15.2.While I think the new straps will be labeled 41mm and 45mm, that doesn't mean they won't work with older watches. The Apple Watch Series 4 comes in new sizes (40mm and 44mm instead of 38mm and 42mm), the good news for Apple users is that the old watch bands fit the new sizes. The Solo Loop and Braided Solo Loop bands are specifically designed for Apple Watch Series 4, Apple Watch Series 5, Apple Watch SE, Apple Watch Series 6 and Apple Watch Series 7.While the Apple Watch has been around for many years, Apple has maintained the same ear design every year.

Before the Apple event, rumors suggested that Series 7 would have a flat-edge redesign, so it would no longer be compatible with older bands.
