I bought both from VIVER, But the Santos Small seems a bit too small for a man. They say the charm of Cartier is wearing a small size, But I previously got a Santos Medium and it would stop working after a day, So I sold it and went with the Small. (Likes 3)I like it because it's comfortable to wear. (Likes 6) (Likes 6)I bought it from VIVER and received it today. It's a watch I bought in China. It's covered by the official website warranty and there are no issues. (Likes 5) (Likes 5) (Likes 3) (Likes 2) (Likes 2) (Likes 2) (Likes 2) (Likes 2) (Likes 2)
