Despite having an extremely larger chest, theApple Watch Ultra Sara compatible also with i belts from some of the other Apple Watches. It can be clearly read on the same Apple website: the compatible bands are those made for the 44 and 45mm Apple Watch, ie the larger models.
Conversely, the bands of the old Apple Watch 38, 40 and 41 mm will not be compatible. Strangely enough, the opposite is also true: the straps Trail Loop, Alpine loop And ocean loop made for the Ultra are also compatible with other 42, 44 and 45mm Apple Watches – including the new Apple Watch Series 8.
It’s not a total novelty: Apple had kept reasonable compatibility between the straps even with the previous generations. However, there are a few things to keep in mind: the bands made for the 41mm models are compatible with the 39 to 40mm Apple Watches, while the bands that came out with the 45mm Apple Watches can be used with the Apple Watches. Watches of 42, 44 and 49 mm.
In addition, the Solo Loop and Braided Solo Loop bands are only compatible with Apple Watch SE and Apple Watch Series 4 or later. In short, we have to be very careful. The risk is that you will buy a band that is not really compatible with your Apple Watch. Fortunately, you can find all the requirements on the official Apple website.
