Although these things happen, though more often in premium products from my observations (same in cars), I know how you feel given this is AP. Even if a new clasp, you would have expect them to have rigorously tested it first rather than have the customer suffer the unfortunate fate. Sometimes human beings tend to overlook the simpler things. If I were AP, I would replace a new bracelet for you, doesn't cost them too much.
Same thing happen to my dad's Honda Civic... the ABS brakes seems to have problems.
After multiple trips to the service centre and changing numerous parts, finally the problem got solved.
And the manager said to my dad "You're lucky, we changed alot of parts and finally knew that the problem is with a small part. But you still get to keep the new parts that are not affected"
My dad told him "No, you're the lucky ones, because if another car come in with the same problem, you will know where and how to rectify it"
So, it's the same thing here.
I see my unfortunate incident as letting AP know there is a problem with that particular part, that it is prone to failure.
Maybe I am naive on my part but I am sure they will throw in some freebies for me.
It happened once.
Like I said, I am interested to see how this whole incident is handled.
It will be a barometer for me wether to stay or ditch the brand.
No brand is above criticism.
