I thought I had seen them all! Not this one! This is a TUDOR OYSTER ROLPH, being all original with a small sized 28.4x35.6x10.2mm. (1.1x1.4x.4 inch) stainless steel TUDOR OYSTER case (by ROLEX). The dial with interesting raised arrow and triangle markers and blued steel pencil hands with red seconds is completely original and untouched. There is a ROLEX OYSTER screw down winding crown. The TUDOR manual winding movement was cleaned and is accurate. This is a smaller, boy’s size watch-made for a man though. I have NEVER seen another of these!
