SEIKO Digital A039 Module Battery Carrier

thingiverse

Hi, This is a custom-made replacement battery carrier designed specifically for the SEIKO A039 Digital Watch. The original part often breaks into multiple pieces when exposed to battery acid, making it difficult to hold the battery in place. This new design requires some assembly, plastic welding, and hand fitting, so it's best installed by a professional watchmaker or technician. The part needs to be fixed with circuit track issues. In this case, I had to solder on a thin brass sheet between the two contact pad areas due to damaged tracks. This process should be done using minimal heat to prevent damage. You'll also need to file a groove into the bottom of the part to fit the battery tang. The original battery tang will need to be cut away from the old part and plastic welded into the new one, which can be easily done with scrap 3DP plastic and a soldering iron. Additionally, you'll need to add a bulge to the side of the part closest to the middle of the PCB to hold it off the board and prevent drooping when the battery is installed. I used plastic welding for this process as it's easier than other methods. The sides of the part will need to be filed or cut down slightly due to its size, so I've added extra material during printing. If the holes aren't fully formed, they won't affect the part but may need to be enlarged slightly. Test fit is crucial, and you'll need to adjust the part to suit your case or movement. In my repair, I had to remove some material from the part to clear the crystal oscillator and get it flush with the side of the PCB. You may also need to remove a little material to clear the speaker. This design is not perfect, but it worked well for me on a current repair. The size of the part presents some challenges, but I think this might be the first part of its kind in the world now.
