Rolex Submariner 16613. The wristband is 18k Gold and SS ( 93153 ). There is another number on the back of the wristband where it attaches to the watch but not sure what it represents, ( 401 with capital B below the 401 ). I don't know how to determine condition so I will say good to fair. It has not been polished and looks great to me. There is a very small chip at the bottom of the crystal that I cannot see without magnifying glass but can feel when I run my finger around the outer edge of the crystal. It works perfectly and has never had an issue in the 22 years I own it. The serial # starts with E so I believe it to be a 1990.
