Cartier watches, their weight and the original weight are the same. The seal is on the lock with the serial number on the watch. May God bless everyone. If you don't like it, believe me, it's a gift that will make you proud. The first time you try it, if you don't like it and want to return it, I will bear the cost of the trip and you will get your money back. If you don't like the ad, a prayer from your heart is enough. May God bless everyone. Watch Size: 42mm Features: Water Resistant Material: Stainless Steel Movement Type: Manual
