Broke in less than a year

I bought this watch for my boyfriend less than a year ago and he wore it normally. The band snapped in half randomly while he was wearing it one day and is now unwearable. When I reached out to customer service to get it repaired I was told the 5 year warranty would not cover it and there was nothing they could do. For such an expensive watch you would think that the company would cover a replacement of the band rather than fight over language in the warranty.
