Review: Saved money and made new - Took my watch to a local repair "specialist" shop. They wanted $50 just to diagnose the problem. I purchased this kit, enlisted a friend with more patients then myself, and it's 100% perfect now. Lots of small parts, so if you're elderly and have trouble with your hands, you will need help. Instructions are clear. (Watch currently charging but working great as before.
Review: Battery life is horrendous - The battery worked but the battery life is trash. If you are expecting this to replace your stock watch battery you will be severely disappointed. Without even playing on the watch or doing anything with it besides just wearing it, it wont even last 24 hours. I put it on in the morning, fully charged, and before I go to bed at night it is completely dead. This is on day 1 so hasnt even had a chance to degrade. Not worth buying.

### ⭐⭐⭐⭐⭐ Works great for galaxy watch
*by W***E on December 5, 2025*

Worked perfectly for my Galaxy watch 46mm 2019. Only problem was the screw driver point was too sharp and I thought the screws were stripping but it was the point on the screw driver not allowing it to fit in the screws correctly. Other than that. Everything works perfectly and the battery is good.
