Gucci 1100l watch battery replace
The back cover does not screw off. You'll need to pry it open where the narrow slots are next to the watch bands. See video J2KkDFXEEJ4 on youtube for how to do it.
You don't need that special tool, I used a pick hook tool from Harbor Freight #66836 to open it up and it worked fine.
To replace the battery, there are two very tiny flat head slotted screws that you need to loosen (don't need to remove them) to remove the battery hold down (carefully note how it goes in, the two sides of the hold down are different), then you can pop the battery out and replace it. It uses an AG1 or SR621SW or 364 battery, not the 379 battery someone mentioned above.
If the battery leaked you can use a q-tip dipped in white vinegar to clean the battery crud off, then use other side of q-tip dipped in iso alcohol to clean that up, then dry it with another q-tip.
To put the battery hold down back, first put the side that is U-shaped in first, then slip the other side under its screw. Tighten that one down, then tighten the other side down. Put cover back on and off you go!
I used the Harbor Freight #38896 magnifier (without the built in lights, used a better light) and it worked great. Those screws are really tiny and they are hard to see. You'll need a very, very small precision screwdriver for them.
