Bergeon 8008 Rubber Ball to Open and Close case Backs Ø65 mm

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

Works as intended
