I have tried to contact Luminox Customer service 7 times. I received automatic responses that they received my emails and they would be geyying back to me. Well, it's been 2 months and no response.Their customer service is Horrible. If this is indicative of their company, this was my last purchase.I am very disappointed in what could have been a nice watch. Don't buy them, they don't stand behind their product. You will notice, everybody has the same complaint.
