Tools to open rolex-style caseback

Hi guys,

I've bought one of these NH35-based AliExpress special awhile back hoping to open it up to play with the movement. But for the life of me, I cannot open this thing up. I have the watch case on a watch case holder and have tried:

  1.  Adjustable case opener (with various pins) - failed miserably as there's no hole for the pin to grip on.
  2. Friction ball twisting the ball counterclockwise - failed.
  3. Friction ball with duct tape between ball and caseback - failed and now stickier. 🥵

Can anyone recommend a tool from Amazon that you've used which works on this type of case back?

The watch:

I have a caseback opening tool for Rolex style from Ali Ex and that works fantastic. Was about 20 bucks and took a bit more than a week to get to me. Especially with tightly screwed backs it’s the only thing that works.

I use extra-strong double-sided sticky tape for carpeting, and my palm. So far no caseback has resisted.

I found this Rolex specific watch case opener.  It also works on Tudor but is not compatible with JLC or any other luxury brand.
