Works! Butâ¦
I just left a review for the more expensive Bergeon ball. My main criticism of that ball is that it is more expensive than what it used to be.This ball seems to be a bit thinner of rubber than the Bergeon ball, which makes it more flexible. The benefit is that you can shape it more easily as you squeeze it into the back of the watch case into whatever shape you need. The problem is that the thinness makes it give a little more if youâre trying to twist off a tight case when you need it to stay stiff instead of flexing. If youâve ever opened a watch with a rubber ball, youâll know what Iâm talking about. It also may not last as long because of the thinness, but I think it will work just fine for most people.It also came with a pump needle, which the Bergeon ball did not! The Bergeon ball was also more flat, and this one was much more full.Iâll try to update my experiences as time goes on if anything changes.

I was skeptical this could remove my watch back. But it did after much effort.

Just what I needed
I have acquired a good amount of tools to use when I need to replace our watch batteries. It has saved us a lot of money. The back of one watch screws off and on. I have a gadget to get it off but I couldnât get things to line up to screw it back on. Started looking at various watch tools and saw this little rubber ball. I thought ð âwhat the heck, Iâll give it a try â and if it doesnât work itâs only a few dollars. Arrived quickly and within a couple of minutes âta da!â Mission accomplished. Glad I bought it.

Vipan Sharma –
The product I received was fully deflated, and there is no way to inflate the ball. There are no instructions also about the same. Useless product, never buy
