Patek Philippe Nautilus Annual Calendar Ref 5726/1A

Patek Philippe is a high-end watch manufacturer synonymous with excellence Two things it is famous for, among a myriad of other things, is the Nautilus sports watch and the annual calendar wristwatch.

In 2016, Patek Philippe put two and two together and introduced the Nautilus Annual Calendar in Baselworld This year, the watch receives a new dial, which sounds trivial, but is actually a significant move We bring you the details and our thoughts on the new Nautilus Annual Calendar Ref.

The Case, Dial, and Hands

The case of the latest Nautilus Annual Calendar remains unchanged relative to its predecessor The stainless steel case is still a comfortable 40.5 mm x 11.3 mm in dimensions and features the porthole-shaped bezel that has made the Nautilus so iconic A screw-down crown allows for a respectable 120 m water resistance rating, sufficient for a swim or shallow diving.

The finissage of the case, bezel and bracelet – alternating between polished and satin finishes – is well-known in the industry for its immaculateness; it is second to none.

Originally designed by Gerald Genta, the Nautilus with its rounded octagonal bezel has since become one of the most recognisable sports watches in fine watchmaking.

Appearance wise, the gradient blue dial which goes from electric blue in the center to almost black in the periphery looks fantastic on the Nautilus Annual Calendar No other changes to the dial have been made, including the lume-coated hands and markers, and the layout of the annual calendar displays
