Keep in mind, Lange movement parts are made of German Silver which is a material where a higher polish is able to be achieved, compared to the rhodium plated brass movement parts that Geneve style manufacturers use. Thus, a comparison between the two isn't entirely fair, as German Silver will generally "look better" to most eyes. It's not necessarily indicative that the team at Patek Philippe has less skill or spends less time on the equivalent polish process of that specific part.
