Ball's claim of 5000G performance

[heb]

Hello,

Since the company uses the ubiquitious, but good, ETA movements, do they actually modifiy them or is 5000G's just a normal spec of the movements?

What do you think:think:?

How do you test 5000G's? I don't think you could reach that level whacking it with a baseball bat. Maybe if you hired Barry Bonds...

And the hammer comes down hard on the crown where the impact is worst.

All the explanations aside, it is my understanding that 5 G's is the equivalent of dropping the watch from a height of 3 to 4 feet onto a hard surface.

May I ask, how you came about this conclusion? I would be interested in seeing the explanation. Watches falling from short distances onto hard objects are very damaging to mechanical watches...

Actually, I've read "wood" surface, not generic "hard" surface, is used for wristwatch "drop" tests. I started a new thread based upon serious discussion concerning Ball Watch real world "toughness".

Hi Warren:
My opinion comes from an article I read some time ago (and don't ask where) since I can't remember as to what the 5G's rating was for. The 5 G's comparison was explained as the equivalent to being dropped onto a hard surface from 3 or 4 feet. This seems to me to be a valid explanation since how else could the 5 G's be explained to us laymen? I'm not saying this is how they tested the watch but only to help us understand as to what a force of 5G's would be the equivalent to.
I hope this helps explain my earlier statement. I'm a solid defender of the Ball watch since I always wear a Ball while I'm working on the railroad, and the shocks they receive on an almost daily basis hasn't altered their time keeping at all.
Cheers
Tim
