The 5811/1G is the Nautilus with date that Patek Philippe introduced in 2022, after the steel 5711/1A had left the collection in 2021.
The design follows that of its predecessor: the porthole-shaped case, the octagonal bezel, the horizontally embossed blue dial and the integrated bracelet. The major difference is the material: the 5811/1G is entirely in white gold, case and bracelet alike.
The case measures 41 mm, slightly more than the 40 mm of the 5711/1A. Inside is the self-winding calibre 26-330 S C with a gold central rotor, visible through the sapphire caseback.
White gold is softer than steel and shows wear in its own way, so on a pre-owned 5811/1G we assess the edges of case and bracelet and the transitions between brushed and polished surfaces with particular care. We compare the numbers with the certificate and check the movement and the clasp.
What a complete set includes is explained in our guide to box and papers.
