Just went through with this. Had a few comments/suggestions for anyone trying this:
Step 1
- I moistened a small hand towel (you could probably use a paperwork) and microwaved it. I put it in a ziplock bag and it worked fine.
Step 2
- I only had two small flat head screw drivers (from an electronics repair kit.) I used one to pry near the microphone then worked the other around. The adhesive is a strip so it may come off on the ring in some areas and the watch body on others. At the end I scraped it from the body and reapplied it to the ring and it seemed to work well when I reassembled.
Step 3
- My watch had a gold ring and I couldn’t find a way to remove it at first. I ended up just using my smallest flat head and got underneath it to pry it off. Went pretty fast after that.
We’ve updated this guide with better photos and instructions. Thank you for your comments and suggestions!
Step 3 (continued)
- As for removing the button, use a small flat head and place it at an angle in one of the spanner sockets. Then gentle tap the end with another object to loosen the screw. Once loosened, it unscrewed pretty easily by using one screw driver.
Step 4
- Similar to step 2, I inserted one then walked one around the outside gentle prying out the innards. Slipping the flat head between the gasket and the inside of the body takes some finesse but once you get about half way around it’s not too bad.
- The innards have a lip that runs around 2/3 the way around that goes under a lip on the body. I found this the most challenging part on removing and reinserting the innards. Just use a screw driver to pry away the body and then use a second to push in the innards. It takes some work. I tore a few parts of the gasket so I don’t think i’ll be swimming with this anymore, but the ring (first step) gives a decent seal against sweat and moisture.
Step 5
- Pretty straightforward; pry the rubber away as the guide shows. You may need to pull firmly to remove the ribbon. I just used my finger as I was afraid my tweezers would tear or puncture the ribbon.
Step 6
- As the guide states the adhesive is pretty strong but it doesn’t appear there is much to hurt between the screen and battery so just pry it away slowly (and evenly.) Once the battery is removed, use a small flat heat to pry the plastic out so you can get to where the battery cable snaps in.
Reassemly
- So like any repair, reassembly can be just as difficult as assembly. I ran into two major struggles: getting the innards ribbon cable reinserted and getting the innards back in the body.
- For the ribbon cable, I was being too gentle when trying to insert. I though the ribbon inserted and then the rubber (pried away in step 5) was holding it in place. No the case; the ribbon should (with a firm press) push back into the female end snugly. My ribbon folded over 90d which gave me a place to press on.
