Hi all I'm about to service my wife's Rolex AirKing model 114234 with the 3130 movement. From what i can tell this movement is the same as the 3135 but without the date complication, so I will follow Mark's great walkthrough for the 3135. Can you please advise on what components I should buy to replace (if any)? mainspring? gaskets? stem o-ring? reversing wheels? ... Also, is there a technical chart available with information on assembly and oiling procedures? Many thanks
