I just sent my SeaDweller for a trip to the spa at the Rolex New York Service center. Clean & Overhaul the guts and brush up the outside. I have not been wearing it since I got the Sub LV so I sent it out to get spruced up and when it comes back I will decide whether to keep it or not. It's 8 years old and probably needs it anyway. It will be good to see it back in tip top shape as well.
