I'm just rebuilding the 565 movement for my 166.0073 Seamaster 120 and I'd like to replace the date wheel as it has a few marks on it. The date wheel I need is the flat one, black numbers on silver background, and not the usual curved one. Cousins have the 5601500A which is the black numbers on silver background but I'm assuming its the curved one? Any help much appreciated Cheers Stuart
