Hi guys,
Please be patient. He will answer your email. If not please send email again to him. I know he always late to reply emails but he surely will reply yours. For me, it took max 2 days to get replied and he replied all my emails. So dont worry, give him time to reply all the emails inside his inbox.
As your problem with faulty watch, i am sure he will take care yours. He is a good guy after all.
