Swarovski comes with a Limited Lifetime Warranty, whatever that means. I called them several days ago because I had lost my objective lens cover for my spotting scope. They asked me for my address and said they'd send one out right away. My warranty registration had not even gotten to them in the mail yet because I asked. But she didn't even ask or mention wether or not I had an American warranty. I was told by the salesman where I bought my scope that it is a 10 year warranty but they seem to honor it on glass whose warranty is way past 10 years old. Pretty cool company. My next optic buy will be Swarovski just for that reason. fatrooster.
