Unfortunately, Apple Watch bands aren't universal. 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. Once you've chosen the right size for your Apple Watch, you can delve into the bands and the different settings of each one.
We will explain the materials of each watch band and how they will feel on the wrist. The quickest way to find out what size Apple Watch you have is to take the watch off your wrist and look at the engraving on the back. The good news is that almost every design is offered for every Apple Watch size from 38mm to 44mm. Apple's printed guide offers a comparison of the Apple Watch size on the wrists for a powerful visual reference.
Apple Watch Series 7 has approximately 20% more screen area than last year's Series 6, and the bezels are 40% thinner. When you buy an Apple Watch band, you may need to specify which watch it is for, large or small, but you can usually get any of the bands for any of the 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. But many of them no longer include options for the 38, 40, 42 and 44 mm size options for all straps.
If you're preparing to buy an Apple Watch, you should consider the wrist size and strap options available to get the best fit. For those who don't have a cloth tape measure, you can take a piece of string and wrap it around your wrist, using a standard flat measuring tape or a ruler to measure the part of the rope that fits around your wrist like a watch would. The Apple Watch Series 7 was one of many announcements made during Apple's “California Streaming” event, sharing the stage alongside iPhone 13 and 13 Pro, a new iPad Mini with USB-C charging, and more. For all Apple Watch bands, you want a snug fit that holds the Apple Watch against your skin for the sensors to work.
To reiterate, bands made for the smaller of the two new sizes work with previous smaller Apple Watch models, and vice versa. Wraparound bands like sports straps are the most tolerant in both situations, and if you have a large wrist, the sports strap and the sports loop strap can fit where other bands don't. Although it wasn't the redesign that many thought it would be, the Apple Watch Series 7 looks slightly different from last year's model. As long as you take off and put on your Apple Watch bands properly, there shouldn't be any wear and tear associated with changing them.
