Apple Watch bands release with a button press and slide out sideways

Changing an Apple Watch band takes about 30 seconds once you know where the release button is. Hold your watch face-up in one hand. On the back of the watch, you'll see two small rectangular slots on either side of the band — one on each side. Inside each slot is a tiny button. Press and hold the button on one side, then slide that band out toward you. It will come free. Repeat on the other side with the second band.

Once both bands are off, slide the new band in from the side, pushing it straight in until you hear or feel a click. The band should sit flush against the watch body. Do the same on the other side. Your watch is ready to wear.

This design works the same way on every Apple Watch model — Series 9, Ultra, SE, and older versions all use the same release mechanism. The bands themselves come in different widths depending on which watch size you own, so make sure any new band you buy matches your watch model.

Key Takeaways

  • Press the small button inside the slot on the back of the watch, then slide the band out sideways to remove it.
  • Slide a new band in from the side until it clicks into place, then repeat on the other side.
  • Band width varies by watch size — 41mm and 45mm watches use different bands than 40mm and 44mm models.
  • You can buy replacement bands directly from Apple or from third-party makers, though third-party bands sometimes fit less snugly.

Which bands fit your watch size

Apple Watch bands come in two main width categories. If you own a 41mm or 45mm watch (the newer sizes), you need bands labeled for those sizes. If you own a 40mm or 44mm watch (the older standard sizes), you need bands for those sizes instead. A 41mm band will not fit a 40mm watch, even though the watches themselves look similar.

The Apple Watch SE uses the same band width as the 40mm and 44mm standard watches. The Ultra uses the same width as the 45mm. Check your watch settings to confirm your size: open Settings on the watch, tap General, then About. The model size appears there.

Third-party bands often work, but fit varies. Some sit slightly loose or require a bit more force to slide in. If you prefer a may provide fit, Apple's own bands click in smoothly every time, though they cost more — typically $49 to $99 depending on material.

What to know about third-party bands

Third-party bands are usually cheaper than Apple's official options and come in more colors and styles. Brands like Nomad, Spigen, and Barton make bands that fit most Apple Watch models. The main trade-off is consistency: some third-party bands fit perfectly, while others are slightly loose or require more pressure to seat properly.

Before buying a third-party band, check the reviews for your specific watch model and size. A band that works well on a 45mm watch might fit differently on a 41mm. Avoid bands listed as "universal" unless the reviews specifically confirm they work with your model — that label often means they fit loosely.

Third-party bands made from silicone, sport loop, or leather tend to work more reliably than novelty materials. If you buy a band that doesn't fit well, most sellers accept returns within 30 days.

How to clean your watch while the band is off

Removing the band gives you a good chance to clean the back of your watch, where sweat and dirt build up. Use a soft, slightly damp cloth — not soaking wet — and gently wipe the back of the watch body and the metal connectors where the band attaches. Let it air dry for a minute before putting a new band on.

If you wear your watch during exercise or in water, cleaning it every week or two keeps the connectors from corroding and helps the band fit smoothly. Don't use soap or cleaning solution on the watch itself, and avoid getting water inside the speaker or microphone openings on the side.

Troubleshooting a band that won't slide in

If a new band feels stuck or won't slide all the way in, first make sure you have the right size for your watch model. A 40mm band will not fit a 45mm watch no matter how hard you push. Check your watch size in Settings again before assuming the band is defective.

If the size is correct but the band still won't seat, the connector pins inside the slot might be dirty. Use a dry cotton swab to gently clean inside the slot on the back of the watch, then try sliding the band in again. Push straight in — don't angle it. The band should slide smoothly without excessive force.

If one side goes in easily but the other side is stuck, remove the first band and try again. Sometimes the connectors need to align just right. If a band still won't fit after cleaning and checking the size, contact the seller about a replacement.

When to replace your bands

Sport bands and silicone bands typically last one to two years with regular wear before the material starts to crack, fade, or lose elasticity. Leather bands may crack sooner if you wear them during exercise or in water. Fabric loop bands can fray at the edges after a year or more of daily use.

You don't have to replace a band the moment it shows wear — many people keep using them until they break. But if you notice the band is cracking, peeling, or no longer holds your watch snugly, it's time to swap it out. Keeping a spare band on hand means you always have a clean option while one is being washed or drying.

Frequently Asked Questions

Can I use a band from an older Apple Watch on a newer one?

Only if both watches are the same size. A band from a 40mm Series 7 works on a 40mm SE, but a band from any 40mm watch will not fit a 41mm watch. Check the size of both watches before assuming a band will transfer.

Do I need to turn off my watch before changing the band?

No. You can change the band while the watch is on and running. The watch won't be affected by removing or installing a band.

What if I lose one of the release buttons?

The buttons are built into the watch body and cannot be replaced by the user. If a button breaks or stops working, you'll need to contact Apple Support about a repair. In the meantime, you can still wear the watch with one band if you're careful not to pull on the side without a working button.

Are Apple's official bands worth the extra cost?

If you change bands often or want a may provide fit, yes. Official bands click in smoothly and feel more polished. If you wear the same band most days and don't mind checking reviews before buying, third-party bands save money and offer more style choices.

Can I wash my watch band?

Yes. Remove the band from the watch and rinse it under lukewarm running water with a bit of mild soap if needed. Dry it completely before putting it back on. Avoid hot water and don't soak leather bands. Most silicone and sport loop bands can handle regular washing without damage.
