Query: Weak straps and hidden conditions on warranty

Watch out when buying these watches. The watch straps are weak, and Swatch only honors any suggested warranties if the seller has some kind of authorized dealer stamp, which my seller - an Amazon partner - did not.My strap broke within a month of purchase. Neither Amazon nor the seller could help me fix the strap or get any kind of refund.I know it was not a once off because I mailed my watch in to the seller to be replaced and they accidentally sent me back two watches with the same problem (one to my old and one to my new address). Obviously they must have watches with broken straps just lying around.
