Use this guide to replace a cracked or broken display on your Fitbit Ionic.

If the frame is deformed, we strongly suggest replacing it to make sure the new display will mount correctly and won’t suffer damage from uneven pressure.

You’ll need replacement adhesive to reattach components when reassembling the device.

To reassemble your device, follow these instructions in reverse order. Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).


Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.


Take your e-waste to an R2 or e-Stewards certified recycler.

It says in the description that you need replacement adhesive when reassembling, but what adhesive do you mean? Adhesive strips, adhesive glue? In all my searching nobody seems to have a good answer. The best thing I could find was b-7000 glue on amazon, but some people say it is water proof some say it Isn’t waterproof, so I’m not sure what to do. Any advice/feedback would be much appreciated!

Hi JJB, it’s very difficult to seal your watch waterproof after a repair but I can recommend this glue. I hope your repair works! Feel free to share your experience with us when you have finished it.
