Review on 🕰️ StFlyBro 2-Piece High Torque Non Ticking Clock Movement Mechanism with 4-Pack Clock Hands - DIY Quartz Clock Motor Kit, Battery Operated Repair Parts Replacement, 7/10in (17.5mm) by Ghostnote Hankins

It's only been a few days since I installed them in my watch. I'll have to wait to rate accuracy and durability. These mechanisms are incredibly quiet. I don't hear a tick. The only problem I had was that I wanted to use the original hands but they didn't fit me so I used the ones that came with the movement, they are shorter. As for the instructions for using carbon batteries, I think if you use low-power batteries designed for clocks and remote controls, you'll be fine. You can find them everywhere
