About This Piece: Works perfectly, a must have. Great case detail. Please Note: This appears to be a Patek Philippe movement, however, since there are no stamps (common for these watches) we cannot guarantee this is a Patek Philippe movement. There's a tiny stamp on the movement "M F" at top "10 40" at bottom "$" at center of the hallmark Works great, fully functional.
