all around great watch, the 5270G-001 has two features that are very appealing to me: unlike 5970 and its predecessors it has a stop seconds feature; and it has a two tone dial. Not since the first series 3970 (approximately 100 pieces) has there been a two tone dial on a Patek PCC. In both models the registers at 3 and 9 are slightly different in color from the background color of the dial. In summary the 5270G-001 truly was a game changer in many important and very appealing ways. Hope you are enjoying your wonderful watch to the fullest. It is very special!
