So, I've started to collect the parts for my 1655 "Freccione", so far I have: Gen Service Dial, Gen Service Hands, Gen MK IV bezel, Gen 1575 GMT movement. Gen old style NOS Tropic 116 Still on the shopping list: Phong's 1655 Mid case + case back Gen 6mm winding crown + tube Gen Bracelet, either 78360, 62510H, 93510 (I'm still deciding although I'm leaning toward the "D link" jubilee) I need to know which 6mm winding crown should I buy. I know that the1655 uses a men's Datejust 6mm crown as opposed to the 1675 5.3mm crown. Has anyone got the correct Rolex part number for the crown + tube? thank you Max
