JEWEL TOOL Large Professional Watch Back Remover Opener Closer Tool | 10mm to 70mm Metal Adjustable Size Wheel | 80mm x 30mm x 10mm Design | Screw Wrench Repair Kit Tool For Watchmaker

This case opener worked great on a large Invicta watch I own. I have a large watch collection, and the other openers I had were too small. This one will work on large case watches, and small case watches, as well. For the money this was a great addition to my collection of watch tools that I use to change straps and batteries. I recommend this tool!

Simple cheap tool. I can buy more if it ever breaks.

Very good product, easy to use

It was a little clumsy to use the first time however, after quickly learning to position the two points it was easy to open watch cases.

Its a nice big opener. Fits in my hand perfectly and I get a better grip. The pins stay snug in the holder. I have bought the smaller ones and always had a hard time trying to keep the pins in the notches on the watch back. This seems a lot better. Very happy with my purchase!

Works very well on my 52 mm watches.

I used this Jumbo Large Watch Case Closer on my Fossel watch. It was useful.
