The new 49mm Apple Watch Ultra will work with most existing Apple Watch bands, according to Apple's website. The device is compatible with bands designed for the larger 42, 44, and 45mm case sizes available for the Series 8 and older Apple Watch models.


It is not, however, compatible with some of the smaller bands that are designed for the 38, 40, and 41mm Apple Watch models. From the Apple Watch site:
You can match most bands with any Apple Watch Series 3 or newer case of the same size. The 41mm bands work with 38mm and 40mm cases; the 45mm bands work with 42mm, 44mm and 49mm cases.

The Solo Loop and Braided Solo Loop bands are only compatible with Apple Watch SE and Apple Watch Series 4 or newer. The 40mm and 41mm cases work with band sizes 1-9; the 44mm and 45mm cases works with band sizes 1-12.
Some bands, such as sport bands purchased for the 41mm Apple Watch, won't work with the 49mm Apple Watch Ultra, but bands designed for the larger Apple Watch models are compatible. Basically if you have a band you've used for the 42, 44, or 45mm Apple Watch models, it should work with the Apple Watch Ultra. Apple also suggests that all Braided and Solo Loop sizes will work with the new larger Apple Watch.

Conversely, the Trail Loop, Alpine Loop, and Ocean Band crafted for the Apple Watch Ultra can also be used with 44mm and 45mm Apple Watches, but not the smaller 40mm and 41mm models.

Its like Apple was listening to the concerns about these products and did their very best to make not have as many compromises.

Lmao some crazy Apple fan on this forum was basically defending Apple that they should make users abandon all their previous Apple Watch band collections, blah blah blah, giving excuses on the behalf of Apple.

Glad to see I wouldn’t have to abandon all my bands from over the years.

I mentioned this in the other thread but I’m very curious to see how they look (older bands on the Ultra and new Ultra bands on the 44/45mm watches).

I think Apple did good in general here with the Watch announcements. The roaming and low power mode will work on S4 and up if I got it right. And now the bands. I think the orange loop looks cool and will maybe get it for my S5.

So once again, the rumor of band incompatibility that makes people go mad is debunked at product release.

Wouldn't be surprised to see a slightly smaller size ULTRA next year if this one is successful, which likely would have band compatibility with the smaller sizes.

I was hoping the new bands would be compatible with my S6, and I'm pleased to find out they are. I'm not pleased to find out they are $100 each. The Alpine Loop looks especially cool, but I'm not spending that much money on a band. Kudos to those who do, though. They look sweet.

Wow, they are some ugly bands. Interesting that the watch is pitched at people who do some crazy stuff and are much more brave than I so you'd think they'd avoid bands that have loops to avoid any snagging.

I like this new direction of the Apple sport band Ultra; it moves away from their lukewarm designs. A design that embraces the idea of adventurers and pioneers in the modern days. Is like the diving watch from important brands, this is the first time I would actually call this more than just a healt care monitor. Unfortunately, digital devices don't hold their value that much.

Anyone willing to bet we see a 46mm Ultra (compatible with 38/40/41 bands) next year?
