You can swap an Apple Watch band in under a minute once you know where to press

Apple Watch bands are held on by two small release buttons on the back of the watch. Press one button, slide the band out, and the old one comes free. Slide a new band in from the same direction and it clicks into place. The whole process takes about 30 seconds, and you do not need any tools or special knowledge — just a little pressure in the right spot.

The method is the same whether you own an Apple Watch Series 9, Ultra, SE, or an older model. The only exception is the original Apple Watch from 2015, which uses a different mechanism, but that model is no longer in regular use. If you have bought a replacement band from Apple, a third-party maker, or found one in a drawer, you are ready to go.

Key Takeaways

  • Apple Watch bands release by pressing a small button on the back of the watch case, not by twisting or pulling hard.
  • You must press the button on the side of the band you want to remove — there is one button per side, and you only need to press one to slide that band out.
  • Third-party bands work the same way as Apple bands as long as they are made for your watch size (38mm, 40mm, 41mm, 42mm, 44mm, 45mm, or 49mm).
  • The band slides straight out horizontally, not at an angle — if it is stuck, you are pressing the wrong spot or not pressing hard enough.

Locate the release button on the back of your watch

Turn your Apple Watch over so you can see the back. You will see a rectangular metal case with a curved bottom. On each side of this case, where the band connects, there is a small recessed button. These buttons are about the size of a pencil eraser and sit flush with the surface, so they are easy to miss if you do not know what you are looking for.

The button you need is on the side of the band you want to remove. If you want to take off the left band, press the button on the left side. If you want to remove the right band, press the button on the right side. You only need to press one button to release that band — you do not need to press both.

Press the button and slide the band straight out

Hold your watch steady with one hand. With your other hand, use your fingernail or the edge of a plastic card to press the small button on the side of the band you are removing. You will feel a slight click as the button depresses. Do not worry about pressing too hard — these buttons are designed to take pressure.

While holding the button down, slide the band straight out toward you. The band should come free smoothly. If it feels stuck, release the button and try again — you may not have pressed it fully, or you may be pressing the wrong button. The band slides horizontally out of the slot, not at an angle.

Insert the new band and confirm it clicks

Take your new band and align it with the empty slot on the side of the watch. Slide it in straight, the same direction the old band came out. Push it in until you hear or feel a click — this means the band is fully seated and locked in place. Give it a gentle tug to confirm it does not slide back out.

Repeat the process on the other side if you are replacing both bands. Most people keep one band on while changing the other, so you only have to do this once per side. Once both bands are in, flip the watch over and check that both bands sit flush against the case with no gaps.

What to do if a band will not come out

If you press the button and the band does not budge, you are likely pressing in the wrong spot or not pressing hard enough. The button is small and recessed, so it can be easy to miss. Try using your fingernail instead of your finger pad — you need to press directly into the center of the button, not the area around it.

If the band still will not move after several tries, stop and let it rest for a few minutes. Occasionally a band can swell slightly from moisture or temperature changes, and a short break can help. If it remains stuck after that, the band itself may be damaged. In that case, contact Apple Support or visit an Apple Store — they have tools to remove stuck bands without damaging your watch.

Choosing bands that fit your watch size

Apple Watch bands are not universal across all models. Your watch size determines which bands will fit. The current sizes are 38mm, 40mm, 41mm, 42mm, 44mm, 45mm, and 49mm. A band made for a 40mm watch will not fit a 42mm watch, even though the difference seems small.

You can find your watch size by opening the Apple Watch app on your iPhone, tapping the My Watch tab, and selecting About. The size is listed there. When you buy a replacement band — whether from Apple or a third-party maker — always check that it matches your watch size. Most bands are labeled clearly with the compatible sizes on the packaging or product page.

Third-party bands work the same way as Apple bands

You do not have to buy bands directly from Apple. Thousands of third-party makers produce Apple Watch bands in different styles, materials, and price points. As long as the band is designed for your watch size, it will use the same release button mechanism and slide in and out the same way.

The main thing to check is that the band is actually made for Apple Watch, not for a different brand of smartwatch. Read the product description or packaging to confirm compatibility. Some very cheap bands are poorly made and may not click in securely or may damage the watch case over time, so buying from a reputable maker is worth the small extra cost.

Frequently Asked Questions

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

No. You can change the band while your watch is on and running normally. The band is a physical component that connects to the case, not to the software, so removing and replacing it does not affect the watch's operation.

What if I lose one of the bands?

You can buy a replacement band from Apple or from third-party makers. You do not need to replace both bands at once — you can wear a single band on one side and leave the other side empty if you want. However, most people find it more comfortable to have bands on both sides.

Can I use an old Apple Watch band on a newer model?

Only if the size matches. A band from a Series 5 40mm watch will work on a Series 9 40mm watch because they are the same size. But a band from a Series 5 42mm will not fit a Series 9 41mm, even though the numbers are close. Always check the size before assuming a band will fit.

Is there a trick to making the band slide in more easily?

Make sure the band is aligned straight with the slot before you push it in. If it is at even a slight angle, it will not slide smoothly. Also, make sure your fingers are dry — moisture can make the band harder to grip and slide. Beyond that, there is no trick — just push it straight in until it clicks.

What happens if I press both buttons at once?

Both bands will release at the same time and can slide out. This is not harmful, but it is not necessary — you only need to press one button to remove one band. Pressing both is useful only if you want to remove both bands at once, which most people do not do.
