Hello I am having a problem again with my watch when its lay flat it works fine but as soon as it's inclined 180 degrees on the left it stops working. I had a similar problem in June this year which it was fixed but it seems to happen again I don't know the serial number but I'll give you the reference from the site where I bought my watch from (Groupon): Groupon code: 0010020YEO
Security Code:2FA17DCB46 Thank you
