Review: Nice Watch - High Quality Original
Review: Have been eyeing this for a year for my husband. Watch enthusiast! It was perfect. Just like the picture. There are some complaints about the band. He felt it was stiff but tried to soften it up but he will probably get another metal band. Beautiful watch.
