Jr8129 how to remove battery

There's a tiny slot you need to find that you can place a very small screwdriver to pry open the back plate. Then carefully lift off the plastic holder using the screwdriver to pry up in a couple of places. The battery is held in place with a "C" clamp which you can bend back with your fingers to pop out the old battery. Then reverse the procedure.

You need a tiny flat screwdriver. Remove the 4 screws on the stainless steel back. There is a little spring clip holding the battery in. Use the tiny screwdriver to unlatch one end of the spring clip. Replace the battery (3 volt lithium Maxell CR2025 or equivalent) positive side up. Re-latch the clip and then replace the back, being careful not to cross thread the screws and secure the back well to keep water out.

TGXL103GRN Check inside watch where the battery holding area has a metal tab to secure it. There's always a big gap btwn the tab/batt area and where it makes keyboard contact. To fix:
1 remove screws and watch back.
2 put tiny screws in dish
3 notice battery condition/position.
4 change batt if necessary
5 fold a tiny piece of paper to fill gap
6 use tweezer to put in place (no foil, no glue)
7 to test if gap is gone, close watch
8 must screw shut + reset to test
9 be patient, adjust as needed
10 take care to not strip screws.

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.

To open the back of a Fossil Am-4065 your best bet is to use a watch case opener like this



You can also use a pair of needle nose pliers, but you then run the risk of damaging your case back. I would advise against it. I've had to deal with quite a few watches that were damaged in such a way.

The opener has an assortment of small pins. Usually you will be able to find some that will best correspond to the size of the grooves on your watch. Then the case opener can be adjusted so that the pins are securely fitted to the grooves so that you can then turn the case back off.



You will need to hold your watch securely while turning the opener, or it may slip out of the grooves and damage your case back. This is not a difficult task, you just have to go slow and carefully.

After you do so you should be able to carefully pop the battery out. Do not use a small screwdriver or other metal tool to do so. It can damage your watch. You can usually use your fingernail. After you do so you can simply read the battery number off and find a replacement. Many grocery store/drug stores and Radio Shack carry an assortment of watch batteries. You can also go to a website like Battery Bob and order the battery, but for one battery it may not be worth it.

Your watch will not have the same water resistance after you open it. Usually a watch like this will at least have it's case gasket lightly wiped with silicone grease before it's re-closed (or have the gasket/O-ring replaced and treated with grease). This should not be a problem if you don't swim or bathe with your watch on.

if its a tiny little spring then those springs you will need to put them in a little hole on top of the movement so they press up against the back of the case when y ou put it on . I am not sure what metal tab you are referring to , but I am pretty sure it is the tab that goes on top of the battery and holds it down.

I am not familiar with Cat watches, but here are instructions for basic watch backs:
Locate a very small tab (or recessed area) on the edge of the back cover. This is the access point for removal. You can find this sometimes by running your fingernail around the back rim, as this tab or indentation can be hard to see.

2Pull out the stem, which releases the back on some watches.

3Get a small flathead screwdriver it needs to be a thin inflexible tip. Use a kitchen knife as a last resort. Wrap the hand you are holding the watch with in a towel or protect your hand in some manner so you don't injure yourself if the screwdriver/knife slips.

4Very carefully slide the blade under the tiny metal protrusion on the back cover (or across the length of the recessed area, depending on which type of cover your watch has). Do not attempt to insert the point of the knife. Use the length of the blade.

5Get under the tab or recessed area and gently but firmly turn the blade upward, popping the cover off.

6When you replace the cover, make sure you line up the stem slot on the cover with the stem of the watch.

It's not easy. You're probably better off brining it to the jeweler unless you already have the tools. You'll need a precision screwdriver set. Under the clock there's a tiny screw. Carefully remove that to pop the clock off the front of the plane -- don't strip it. Then get a standard flathead screwdriver to remove the cover behind the clock. Just turn it so that the tabs on the cover appear in the little openings around the edge. It should then fall out. If not, use a tiny screwdriver to remove it.
Under there is the clock. Remove the plastic spacer. You'll see the tiny little battery, which is held in by a tiny metal arm. Move the arm and the spring behind the battery will pop it up a little. Use a tiny screwdriver to carefully remove the battery. The battery is SR626SW.
Have fun putting it back together! Whoever designed this thing is on my s-list.

You will need to look for any screws holding down a plate over the battery. Sometimes these only need to be loosened and sometimes they have to be removed. Sometimes the plate can be lifter slightly and the battery slide out from underneath. I hope this helps you. Best luck
