Dear Sir,
My watch delays the time considerably, it delays 5 minutes every one hour when it is fully winded. It delays more afterwards. Within 18 Hours, it delays more than 1.5 hours. I sent two emails with full videos that shows this situation. 
I was asked to return the watch so that the factory in Germany refurbish it, However, I will send the watch that I hardly used, if you notice the problem, then I would like to get a refund into my bank account instead of fixing it. I don't usually wear refurbished watches. 
Best Regards,
