IWC Warranty issues

[AlanThomas]

Looking for some help, a friend of mine has an 11 month old IWC chrono which has stopped working (button seems to have jammed) it has been kept in pristine condition and having sent it off to IWC via the purchasing jeweller they have sent a report through claiming that the defect is NOT covered under warranty and is down to damage causing the failure? The bill for repair is £1400 and clearly hard to swallow so ive been whether this can be argued but ultimately unless they accept this is a failure with their watch and not outside influence I guess he's stuck with the bill? Anyone had any similar experience?

Thanks in advance!

Iam pretty sure its the Chrono pusher that wasn't working properly (button click done and didn't return to original position) ive been told the bill includes £400 odd for a service (why its 11 months old!) and a new crystal glass as it apparently had a scratch on it which my friend said he had never noticed!
