The Patek Philippe 5531R-001 was introduced at BaselWorld 2018, as a follow up of the two 5531’s introduced in celebration of ‘The Art of Watches Grand Exhibition’ in New York 2017. It features a rose gold case with a cloisonné enamel center, the latter this time depicting a Lavaux (Switzerland) landscape.Ref. 5531R-012 is identical to the 5531R-001 though this has Beijing rather than Hong Kong on the city track. It remains unsure when the change was implemented.
