The delivery time was extremely long, finally arrived the clock was broken. Contact with the seller was lousy waiter. He wanted me to send back the clock at my expense to Hong Kong. Despite direct contact with the Amazon customer service, the seller could not be moved to a replacement watch to send or to refund the money. Then on the AZ-guarantee I received from Amazon the money back. The clock now languishes still with me around, I'll dispose probably in half a year.
