Remove the old band first
To change your Apple Watch band, start by taking off the watch. Hold it face-up in one hand and locate the band release buttons — there are two small rectangular buttons on the back of the watch, one on each side where the band connects to the case.
Press and hold one of these buttons while gently sliding the band away from the watch body. The band should slide out smoothly. Repeat on the other side. If the band feels stuck, you are pressing the right button — just apply steady, even pressure rather than forcing it.
Once both sides are released, the old band will come free. Set it aside if you plan to use it again later.
Key Takeaways
- Both band release buttons must be pressed simultaneously or one at a time to slide the band out — they are located on the back of the watch where the band attaches.
- Apple Watch bands are not universal; you need a band designed for your specific watch size (41mm, 45mm, 40mm, or 38mm).
- Third-party bands work with Apple Watch as long as they match your watch size, though Apple's own bands tend to fit more precisely.
- The process takes less than a minute once you understand where the release buttons are located.
Slide the new band into place
Take your new band and align it with the slot on one side of the watch. The band should slide in smoothly without forcing. Push it straight in until you hear or feel a click — this means the band has locked into the release mechanism.
Repeat the process on the other side of the watch. Make sure both sides click into place. If one side does not click, remove it and try again; a band that is not fully seated can slip off during wear.
Check the fit before wearing
Once both sides are attached, put the watch on your wrist and fasten the band the way you normally would. The band should feel secure and not rotate around your wrist. If it moves or feels loose, remove the watch and check that both sides are fully clicked in.
If the band still feels loose after confirming both sides are locked, the band may not be the correct size for your watch model. Check the packaging or product listing to confirm the band matches your watch's case size.
Know which bands fit your watch
Apple Watch bands are sized by the watch case, not by wrist size. A 41mm band will not fit a 45mm watch, even though the difference seems small. Check your watch model and case size before purchasing a replacement band.
You can find your watch size in the Apple Watch app on your iPhone: open the app, tap the My Watch tab, go to General, and select About. The model information will show your case size. Alternatively, look at the back of your watch — the size is printed there in small text.
Third-party bands work with Apple Watch as long as they are designed for your specific case size. You do not have to buy Apple's official bands, though they tend to fit more snugly than some third-party options.
Understand the different band types
Apple Watch bands come in several styles, each with a different fastening method. Sport bands use a pin-and-tuck closure. Leather bands and some fabric bands use traditional buckles or magnetic closures. Solo Loop bands are one continuous circle with no clasp — you slide them on like a bracelet.
The release mechanism on the back of the watch is the same regardless of band type. What changes is how you fasten the band once it is attached to the watch. If you are switching from a sport band to a Solo Loop, for example, the attachment process is identical, but the way you secure it to your wrist will be different.
Troubleshoot a band that will not slide in
If a band will not slide into the slot, first confirm you are pressing the correct button. The release buttons are small and easy to miss. Press firmly and hold while sliding the band straight in — do not angle it or push at an odd angle.
If the button is pressed and the band still will not move, the slot may be dirty. Use a dry cloth or a soft brush to clean the slot on the watch body, then try again. Lint or debris can prevent a band from sliding all the way in.
If you have confirmed the band is the correct size for your watch and the slot is clean, the band itself may be defective. Contact the band manufacturer or retailer for a replacement.
Keep your old bands organized
If you own multiple bands, store them in a cool, dry place away from direct sunlight. Leather bands should be kept away from moisture. Sport bands can be rinsed with water if they get dirty, then air-dried completely before storing.
Many people keep a small box or drawer dedicated to watch bands so they can swap them out based on the occasion or outfit. Since changing a band takes less than a minute, having several on hand makes it easy to customize your watch throughout the day.
Frequently Asked Questions
Can I use any band on my Apple Watch?
No. The band must match your watch case size — 41mm, 45mm, 40mm, or 38mm. Third-party bands work as long as they are designed for your specific size. Bands from a different size will not attach properly.
What if I lose one of the band release buttons?
The release buttons are part of the watch case and cannot be replaced by the user. If a button breaks or is missing, contact Apple Support or visit an Apple Store. The watch may still function, but you will not be able to change bands safely.
Do I need to turn off my Apple Watch to change the band?
No. You can change the band while the watch is on or off. The band change does not affect the watch's function or data. Simply remove the old band and attach the new one.
Why does my new band feel loose compared to the old one?
Different bands have different tolerances and materials. A third-party sport band may fit slightly looser than an Apple sport band, even if both are the correct size. If the band rotates around your wrist or feels unsafe, try a different brand or contact the manufacturer.
Can I wash my Apple Watch band?
Most sport bands can be rinsed with water and mild soap, then air-dried. Leather bands should only be wiped with a dry cloth. Check the care instructions that came with your specific band, as different materials have different requirements.
