Buy Apple Watch Ultra 3 Bands Online
The Apple Watch Ultra 3, released in September 2025, keeps the same 49mm titanium case as the Ultra and Ultra 2, adding satellite communications, 5G capability and a larger display in the same housing. Bands sized "44/45/46/49" are designed to fit this case, so the OzStraps range is compatible. The best-selling Silicone Apple Watch Band leads with 919 reviews, alongside the Black Milanese Loop and a full range of styles across every material. Everything ships fast from Australian stock with a 12-month local warranty and a satisfaction guarantee.
Which Bands Fit the Apple Watch Ultra 3?
The Ultra 3 uses the same 49mm case size as the Ultra and Ultra 2, taking bands sized "44/45/46/49". Bands sized "40/41/42" are too small and will not fit. Because the Ultra's titanium case has a more pronounced, raised lug design than the standard Apple Watch, it's worth double-checking fit and finish with individual product photos or reviews before ordering, particularly for structured styles like stainless steel bracelets. The Apple Watch Compatibility guide has more on sizing across every series.

Frequently Asked Questions
What size bands does the Apple Watch Ultra 3 need?
The Ultra 3 uses the same 49mm case as the Ultra and Ultra 2, taking bands sized "44/45/46/49". Bands sized "40/41/42" are too small and won't fit.
Will Ultra or Ultra 2 bands fit the Ultra 3?
Yes. All three generations share the same 49mm case size, so bands sized "44/45/46/49" fit across the whole Ultra range. Given the Ultra's more pronounced, raised lug design compared to the standard Apple Watch, it's worth checking individual product photos or reviews for fit and finish before ordering, especially for structured styles like stainless steel bracelets.
What's new on the Apple Watch Ultra 3?
The Ultra 3 adds satellite communications for messaging and Emergency SOS without phone or Wi-Fi coverage, 5G capability, and a larger display within the same 49mm case. It's also certified for scuba diving to 40 metres. The case size and band connector are unchanged from the Ultra 2, so band compatibility isn't affected.
How do I change the band on my Apple Watch Ultra 3?
Press the small release button on the back of the watch case, slide the old band out, then slide the new band in until it clicks securely into place. No tools are required, and the band-changing guide shows each step.
