Query: Poor build quality

I got this watch as a birthday present and fell in love with it. But my delight did not even last a month. The material used for the strap is very poor quality and since I work with a laptop on a desk, the constant rubbing against the desk caused the silver/gold layer to scratch off revealing an ugly copper core. I had to return the watch back to Tommy Hilfiger and they honoured the return by giving me a full refund.It is unfortunate that they used sub-standard material because the watch design in itself is very classy.
