Nautilus — Steel

Launched in 1976, the Nautilus was Patek Philippe's first true sports watch. The porthole case, attributed to Gérald Genta, has anchored the model across all subsequent generations, and the 5711 represents its most refined configuration: time and date within the original 40mm format.
