From inside the biz, dont take it to a jewlery store. they will put their charge on top of what rolex charges them itll be 250 + just for diagnostic. call rolex and send it to the nearest service center, which i beleive is in new york. that way you know its repaired right. if it has been modified however, they will not touch it.

some stores have their own repair people some send it to others. Eco drives are not hard to repair and whoever was talking about that citezen can repair it at their center they just want more money from you.
