JOREST Watch Battery Replacement Tool Kit, Watch Wrench Back Remover for Rotate Open Watch Cover, Watch Case Opener Set with Watch Back Remover Holder, Only for Grooved Watches

Works great! Can buy batteries for $2-3 so saves lots of money.

Works exactly as described. Makes battery replacement way easier than using the wrong tools..

Not professional quality, but the few times you will use this in your home, it will work just fine. Good kit!

Good kit, I swapped out three batteries thus far without issue and could open and replace the back of my watches with ease. I recommend a good light and magnifying glass for the actual battery replacement step.

This tool set can open the back of a watch with a screw-in case back, unless the case is screwed on too tightly. I had several watches that needed to have their batteries replaced. If the back of your watch has a set of six small slots in a hexagon pattern, this tool set can usually do the job. I say usually, because two of my watches were screwed down so tight that these tools couldn't supply enough torque to open them up.I took both watches to a local jewelery store. The owner could open up one of them with his set of tools, but he said that one of the watches was impossible for him to open. The factory had probably stripped the threads during assembly.So, this tool set can open up most watches with screw-on backs, but not all of them. Don't apply too much torque with these tools. If they slip, you could really cut up your hand.Most of these watches have thin rubber O-rings. These O-rings may or may not survive the process of opening up the backs. If you have a dive watch, and plan to take it scuba diving, you will want to take it to a jewelry store that has a pressure test chamber. Dive watches need to be serviced by professionals.

Needed yo change the batteries from my watch collection. It was very frustrating yo align the tool and tighten it to unscrew the battery cover. I scratched the back of my watches multiple times trying to unscrew the cover. It got the job done but not with ease!

Very cheap very easy to use. Please do not go out and spend a bunch of money on a watch repair kit. This does the job. Great product.

Does a great job. Would like to see more of the grip plastic covers but the price and functionality is on point!
