  • Case Back Wrench Opener

    It was easy to understand and use. It did exactly what I wanted it to do. I have used it 5 times since it arrived and worked well on each watch. This has already paid for itself in not having to drive to a jeweler and having the batteries changed.

    • How did the image on site compare with the actual product? The image was exactly what I received.
    • Please tell us about the quality of the product. It is a well made product.
  • Watch case opener

    Saves me money, instead of taking my watches to have the batteries changed at watch repair shop, which is very expensive, i now do it myself. Good tool to have.

    • How did the image on site compare with the actual product? As see in the internet. Even better!
    • How accurate was the sizing? Perfect
    • Please tell us about the quality of the product. Handles well, easy to use and does the job right the first time.

  • Fifty-fifty

    I had two watches, same brand, same problem - needing new batteries. After an hour of working on one, I got the back off and the battery replaced. however the other watch I could never get the back off of. This is definitely not what a jeweler uses as they can flip off the back of a watch with ease.

  • case opener

    This product does not come with any instructions so before you scratch up the back of your watch it would be nice to know how to attach and use the product. First time I have been unhappy with Overstock.

    • How did the image on site compare with the actual product? ok
    • How accurate was the sizing? ok
    • Please tell us about the quality of the product. I cannot tell about the quality since I cannot use the product

  • Perfect for changing your own batteries

    I have used this on several of my high end watches, (Bolivia Ect.) no scratching due to the wide selection of tooling allowing you to always get a tight fit on the watch back.

  • Lousy wrench stay away

    Uusally i dont write reviews. But this wrench i bought really boiled my blood. Its of really cheap materail. The handle came off before i use it. And the size of the watch i can effectively use is 35mm not what is stated. So stay away unless you really want to know for sure what i said is true!

Product Q&A

Ask a Question

Description states it is for most screw watch backs. All of the watches I've seen and opened were pried off (snapped off). Does this tool work on snap off watch backs. Thank you. lizzards8 on Mar 13, 2012

Answer This Question

Unfortunately, this tiem would not work with watches that have snapped together cases as does not have the required thin edge needed to remove the back casing. overstockcustomercare1 on Mar 14, 2012
