    This is not to be critical of the author as this is a well done guide. This is only a CAUTION to make sure that individuals do see this prior to prying the motherboard apart. A portion of the step that is not stated or pointed out here are the two Phillips head screws that MUST be removed from the motherboard as the picture in Step 5 will show that those screws have been removed. You must remove them or you will break your motherboard. Thanks for the great guide!

    Thanks for the heads up! Looks like I missed including that step. I made sure to add it in.

  5. Make sure to have the two Phillips head screws completely removed before attempting the following steps. Pressing on the small black plastic area will give you leverage to pull off the motherboard gently. Do NOT flip the motherboard without first detaching the battery's ribbon. The motherboard will still be connected by a ribbon. Only the battery's ribbon will be detached (Marked by the red arrow in the second photo). Using a flat tool to get underneath the ribbon will lift it up allowing you to flip the motherboard over.

    • The original battery will most likely be attached to the motherboard. A spudger will be needed to detach the battery from the motherboard. Note: Use caution, gently inserting and lifting as it allows. Use of any sharp or pointed tools can rupture the battery and will cause it to burst.

  6. Insert the new battery and test for power.

Not a comment but a question: What happens with the waterproofing of the watch with this?

Arthur Mize - Reply

Of course with a take apart of any device the waterproofing will be gone unfortunately.

Mister HD -

Id heavily consider rewriting step 4. I almost pried the board off with the screws still attached because I read from left to right on the pictures. Device is okay but I was assuming an entire unit attached with screws was coming out of a shell. Good guide otherwise, thanks
