JorestJOREST 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

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.

This kit was a complete set of tools for opening a watch and changing the battery. It allowed me to easily replace the battery on a Seiko watch. Each piece was well made and was exactly what was needed. A remarkable value for the price.

Did everything that we needed it to

Wow, I’m bummed I didn’t get this years ago! This little kit has saved me hundreds of dollars getting batteries replaced by jewelers. The wrench is a little tricky to use, but it works once you get the hang of it. The tweezers And screwdriver are a huge help. Highly recommend getting this kit to change your own batteries at home for a tiny fraction of the cost of a jeweler.

Not much to say. The wrench works well for removing the back of the watch. It's available separately. But for a couple bucks more, the holding devices makes things even easier.

Overall, did the trick as my hubs needed a new battery in his watch. However, the holder to hold the watch while you loosen, did not work. You could put it in and tighten but then minute I tried to undo the back of the watch, it would pop out. Ended up just holding the watch with my hand. Used the other tools to help open and add new battery so 3 stars for still be able to use.

Contained everything I needed to open the back covers of all my watches and replace the batteries. I saved a small fortune doing it myself instead of taking them to the shop. Well worth the money

This tool worked fine on most of my watches, but I stall had to take one watch to a watch repairman when it didn't.
