Apple Watch Bands Are Size-Grouped
CELI RAE offers bands for multiple Apple Watch case sizes, but not every product is available for every watch. Always select the connector size shown on the individual product page.
Apple Case-Size Compatibility
- Bands made for 38mm, 40mm, and 41mm cases are mutually compatible.
- Bands made for 42mm, 44mm, and 45mm cases are mutually compatible.
- 46mm bands are compatible with 44mm, 45mm, and 46mm cases.
- 49mm bands are compatible with 44mm, 45mm, and 46mm cases.
- Bands made for 44mm, 45mm, or 46mm cases can also connect to a 49mm Apple Watch case.
These groupings describe connector compatibility. The band length, shape, proportions, and intended use can still affect fit and appearance.
Apple Watch Ultra
Apple Watch Ultra uses a 49mm case. Some 44mm, 45mm, and 46mm bands can connect to it, but CELI RAE recommends purchasing only products specifically marked Ultra Compatible. Certain slim, delicate, or jewelry-inspired designs may not be offered or recommended for Ultra models.
How to Check Your Watch
Look at the engraving on the back of your Apple Watch case, or open the Watch app on your paired iPhone and review the device information. Match that case size to the option listed on the CELI RAE product page.
Important
Do not force a connector into the watch. A correctly sized band should slide into the channel and lock securely. If it does not click into place or remains loose, remove it and verify that you selected the correct size and orientation before wearing the watch.
