DIY Watch Battery Change With Items You Already Have

In this video, I'm going to show you how to change watch batteries using only 3 simple tools you can find at home. It is very straightforward. You don't need any special training to do it. The watches I am using to show you are a children's watch by Swatch and a Tissot watch. Both are Swiss-made. The 3 tools I'm using are a small non-magnetic screwdriver, a pair of tweezers, and a knife sharpening stone. First, I'm going to change the battery for this watch. It has been over 2 years since the last change. The battery is covered by a white plastic cap. Above that, it says the type of battery this watch uses. It's a 377SR626SW for this model. I got the same battery model on Amazon. If by chance you need the same one, the link is in the description below. I have washed my hands before this. To minimize any oil on my skin, and I'm trying not to touch the battery with my fingers at all. Because the groove next to the cap is very small, you won't be able to open the cap with just your fingers. Here I'm using a pair of tweezers. As far as they have a pointy tip, it will work. You can even use eyebrow tweezers if you want. What I need to do is to get one of the tips into the hole next to the white cap and lift it up. Now you can see the other side of this lid. The section in white is plastic. Everything in black is rubber. The middle circle is used to push the battery in place. The circle around is the seal to prevent any moisture getting into the watch body. To get the battery out, I place the tip of my tweezers into the tiny hole next to the battery on the right-hand side. When lightly pushing in the opposite direction, I also push the battery out of its seat. This is the worn-out battery. To get the new one in place, I first put the battery in the seat with the flat side up and the other side down in position. I put the tips of my tweezers on the side of the battery and nudge it gently into place. Now the battery is in place. I can just put the lid back on and press it. You can hear the click, that shows the lid is sealed. That's it for this watch. I will recycle the old battery. It's 10:22 at the moment. Before returning it to the owner, I need to set the time right. I'm sure she will be happy to have her watch working again. For this watch, I only use one tool. That's a pair of tweezers with pointy tips. This is the second watch I'm going to change the battery. It is a Tissot women's watch. The model is PR100. It was September 2022, last time I put the battery in. So it has lasted more than 3 years. The watch stopped working recently. To give myself more working space behind the watch, I unbuckle the belt. This watch has a snapback. To expose the battery, I need to remove the back. My nails are quite hard, but they are not strong enough to open it. Before opening it, I need to see how the back is orientated, so when I close it later, it needs to be in the same position. In this case, the word Tissot is at the top of the watch in the 12 o'clock position. This is a random non-magnetic flathead screwdriver I found in my place. I think it came with some DIY project. I use it once and put it aside. The tip measures 4mm wide. If this is 3mm wide, it will still work. Length is 9.5cm, just under 4 inches. Obviously, the edge of my screwdriver is thicker than the gap between the case and the watch back. To make it work, I need to make the edge thinner. Here I use a wheel to grind the edge thinner. You can use a basic knife sharpening stone. The idea is to make the edge thin enough to get into the gap between the watch case and the lid. Previously, I used a watch case opener to open the back. If you want to see how I did it in that way, the link is in the description below. With a thinner edge on my screwdriver, it will work this time. All that I am doing is to get the edge of my screwdriver into the gap to push it open. Here I am, it snapped open. And that's the battery I'm after. I use the same pair of tweezers I used for the swatch earlier. The pointy tips allow me to easily pick the battery out of the seat. This is my new battery, the same as the one that came out of the watch. Even I have pre-washed my hands, you can see in this entire process, I'm not touching anything inside of the watch case with my fingers. I place the battery back in its seat, and use the tweezers to press it into position. Before putting the case back, I press the battery just to double-check it is properly seated. Before closing the back, I want to clean the edges with a dry Q-tip. This step is optional. It's not too dirty in my case. To close the back, you can either use a watch press tool or just close it with your hands. As this video is about using the most basic tools to change batteries, I'm not going to use a press. To place the back, I need to make sure the word TISSOT is at the 12 o'clock position as before. Otherwise, it won't work for this watch. Next, I press hard on the back with my fingers. But if you are interested in using a watch press, I have a link in the description below. It's a very straightforward process. Once the back is on, set the time and date. Job done. This battery will last for another 2 to 3 years. I don't have those expensive watch repairing tools. From the beginning to the end, I have only used 3 very basic tools. Hopefully this helps. See you in the next video.
