For sale is a beautiful Omega Speedmaster Professional "Sapphire Sandwich" with the much desired see through case back and sapphire crystal showing off the Omega 1863 movement. Features a 42mm stainless steel case, the classic black dial on an Omega stainless steel bracelet. The movement runs strong and not in need of a service any time soon.
