This 34.5mm Rolex Oyster Perpetual ref. 6284 semi-bubbleback dates to 1950 with a 63572XX serial number. The last two digits are (commonly) worn away from the old bracelet. The white dial with original triangular markers was restored to perfection and the hands were re-lumed. The Rolex NA automatic movement was just cleaned and is accurate. The Rolex Oyster case glistens! The diamond markers, Dauphine hands, and blued steel sweep seconds add to the fine vintage look!
