BERGEON 8008 Rubber Ball to Open and Close case Backs Ø65 mm, black,white, Open

Works as intended

The BERGEON 8008 removed this type of screw on caseback with ease. The first time I turned the ball the caseback started to unscrew. (Fantastic and well pleased) no marks on the caseback.

Good product, comes ready inflated in a box and works just as it should.

My Omega Seamaster developed an easily fixed issue, IF you can get the back off. With this, I was able to get the back off and fix the problem. Does what it says it will do, can't really ask much more.

Tiempo atrás cuando lleve al relojero este Casio que muestro con la bola de goma BERGEON 8008 lo rayó de su tapa roscada de Titanio material de especificación aeroespacial que todo relojero sabe que es delicado cuando se usa para acabado, cuando lo abrió el relojero lo rayó, ahora con la bola de goma cero rayones y pude pulir la tapa trasera con todo cuidado para rebajar el rayón que le dejó, es de gran calidad, se adhiere fuerte, recomiendo su compra.

A quality tool.

This is a basic grippy rubber ball designed to remove screw-type watch backs. I don't see how it would be any different from a more expensive model by the original company that makes these (Bergeron). As others have pointed out, this comes only partially inflated and you will need to fully inflate it using a bike pump or equivalent with a needle adapter. This will open many watch backs once properly inflated, but don't expect miracles. A Rolex clone opened no problem, but a genuine Omega Seamaster wouldn't budge and required a watch back wrench. Also make sure your watch isn't a pry-back first, as this has no effect on those!

Good quality, good packaging

Amazing! Who knew a simple tool that is so cost-efficient for it’s purpose existed? Also, love the 8-ball design! Works great, fits perfectly!
