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

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.

Alles OK, hat eine feste Uhr aufgebracht.

Kastade pengar!

After gouging an old (thankfully not precious) quartz watch to change the battery, I thought there had to be a better way for a non-expert to open a watch! It's the 8008 to the rescue. When I first received the ball (in a crushed box, thanks to Amazon's habit of shipping boxes in envelopes!) it was pretty weakly inflated. In this state, it simply could not be coaxed to open a watch. After inflating it to a reasonably firm state (with the standard needle valve), it works like a charm. So that is the only gotcha about this great product. Buy it, make sure it is pretty firm, and enjoy not scratching your screw-back watches with metal tools.

Good quality, good packaging
