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

After seeing so many knock-off versions of these watch case opening balls being sold online, I specifically wanted the authentic Bergeon 8008 Rubber Ball, and I am extremely happy with my purchase. You can immediately tell the difference in quality once you have it in hand. The rubber material is excellent. It is soft, very grippy, and perfectly designed for opening and closing screw-down watch case backs without scratching or damaging the watch. The grip it provides is outstanding and makes removing case backs much easier and safer compared to using metal tools that can easily slip or leave marks behind. It is also the perfect size with a circumference of 65mm. It is easy to hold and use. What really stands out is the overall build quality and feel. This is clearly a genuine Bergeon product made from high-quality materials, not one of the cheaper imitations that tend to lose grip or wear out quickly. It has just the right amount of firmness while still remaining flexible enough to conform to the case back surface for maximum traction. If it gets dusty, simply rinse it off with water and it will regain its tactile grip. As someone who has gotten more involved in watch collecting and basic watch maintenance, this tool is already becoming an essential part of my kit. It works exactly as intended and gives me much more confidence when opening watches. Overall, I am very happy with this purchase and can highly recommend the authentic Bergeon 8008 to anyone looking for a reliable, high-quality watch case opening ball. Definitely worth spending a little extra for the genuine product.

I bought several different case openers in the past most pretty crappy. A while ago I did buy a two pronged one where the prongs slide on a metal rail for adjustment. It is extremely well-made but still made me nervous about opening case backs. Even with Kapton tape as a protective shield in the right places, it would mar the notches a little on some. After watching YouTube for a while and getting re-interested in watches, I saw that almost every watchmaker had a ball and usually this one in particular. I thought $15 was quite a bit for a little ball but once I got it, I laughed at my years of caseback opening stupidity. I haven’t found a case back yet that it can’t open. I haven’t touched any metal devices to my case backs since I got it. Even if you’re not into watches and just own a few for changing batteries and other things, you’ll chuckle at how easy this thing makes case back removal. I can’t believe such a simple thing works so well.

A perfect rubber ball to open the back cases of most watches that I have. It does not work for everything, but it worked for the watch I needed to be opened. thanks.

Awesome had a cheap one and it sucked this real one works great.

I paid a lot of money for this ball to say Bergeon on it, so I think it's worth the price. Highly durable, well made ball that makes watch back removal easy.

Bought it with the intention of opening a polygonal caseback. Sadly the ball failed to provide enough grip to open the watch. The ball is well made and incorporates a valve for refilling its air content. Grip is provided by the nature of the material , not by a coating or finish. Therefore I anticipate that its performance should not degrade with use. If your caseback is not very tight, or you just need a quick tool to finish the openning process, give this a try. If you are looking for a tool to open tight casebacks with strange shapes or fluted perimeters, you might be better served with other tools.

I have a small Invicta watch collection where this ball worked on about 1/4 of the watches, but the others were just too tight. After I used a watch holder in a vice and the 3-prong tool to break them loose when they were brand new, I then retightened them with this ball. Now, I can open ALL of them up with the ball whenever I need to replace the battery without the 3-prong tool for fear of scratching them, works perfectly.

great watch ball

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.

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.
