Rolex oysterquartz datejust value?
 

A friend of mine is thinking about selling this oysterquartz datejust Rolex. it has some scratches, crystal is fine, great working condition. what would be the value for this? how much does it cost to service it at RSC?
sorry the pics are not the best, i took them with a camera phone.
