Casio W-800h Mod (2026)

Place the W-800H module into the new metal case. Ensure the alignment is correct so the buttons line up with the contacts on the module. This is the most frustrating step; you may need to use tweezers to adjust the module's position so the buttons click satisfyingly.

Go to Amazon, buy the base watch. Order a set of small screwdrivers. Join the r/casiomods subreddit. And remember: If you break it, you are only out the price of a pizza. Press the AC button and try again.
