Namley,  I have bought a watch from your website not while ago, model Casablanca Theorema GM-101-3, unfortunatley it is not performing as i have expected it. I wind it a full circle as i should , but as time progresivly passes, it stays behind the acctual time. For exmp. If i wind it and set it at a 6 p.m., after 5 hours, natturaly it is 12.p.m., but on my Casablanca Theorema it is lets say, 10 p.m., and that happened a few times, no matter how much i wind it. I would like to note that is has never been in touch with water, not even a single drop, hit, droped, washed with any chemical agents, exposed to heat or anything that would damage the estetic or the acctual mechanism of the watch.
