Tuesday Tools – Case Opener Update

by J.Peter

Tags: , ,

A while ago I wrote about all of my case openers and I mentioned a little sticky ball available online fairly inexpensively which is supposed to be able to open most screw back watch cases. Here is the follow-up:

Case BallI finally got the magic case opening ball today and it was well, a big disappointment. I tried it on 5 watches today and I was only successful in opening one of them. Thankfully, I have professional grade tools for opening all of these watches. The ball succeeded on a Tag Heuer Link, but failed on: Rolex 31mm Datejust, Rolex Lady Datejust, Movado Chronograph and ladies Seiko 5. It would appear that if the backs are on as tight as they should be, the ball fails. My overall opinion is that my son is going to enjoy his new little ball :)

    I am a first-year student at NSCC.

    A guy in my class has had good luck with a similar ball. I’ve been able to open cases that the case opening tool couldn’t open just by breathing on my hands and twisting.

    Maybe it is all in the wrists. :D

    PS. I just discovered your blog and I love it!

    This ball has never failed to open a caseback – worked on about 15 or 16 watches. All except a couple have been opened from their factory-fresh tightness. So I doubt it’s true that if it’s closed as tight as it should be the ball won’t open it.

    This ball puts the others to shame and will save you a bundle!
