The iconic Nautilus is very popular these days that is why Patek Philippe is riding this popularity with newer references. Moreover, the Patek Philippe Nautilus Annual Calendar 5726/1A comes with a breath of a needed update, a cool and very trendy gradient blue dial.
I like this color as it plays with light in a beautiful way. Patek knows about this since they have been using this style in most of their new watches now. The color starts from brighter blue from the center of the dial to darker blue on the periphery of the dial. This trains the eye to look at the dead center, and from here you can easily see and appreciate the complexity of the timepiece. Fresh look or not, this is indeed a cool color when paired with the steel case which I will talk about later on. The dial is also very legible with a balance layout wherein we see the day and month at 12 o’clock and the date at 6 o’clock with moon phases. Since you will always be directed to look at the center, everything falls in to place quite easily. The annual calendar here also requires only one adjustment to be made per year.
As for the case, it is definitely a nautilus, classic complete with an integrated bracelet with foldover clasp. At 40.5 mm diameter by 11.3 mm height, it is smallish for me so this is perfect for dressy occasions. Compared to other compact complicated watches, this is actually not so thin but forgivable since we have a nautilus case. Moreover, the polished and satin-finish steel case looks really good and fitting for the new dial design. We also see a sapphire crystal in the front and back with screw-down crown that achieves a nice 120m water resistance.
Finally, powering the new Patek Philippe Nautilus Annual Calendar 5726/1A is the popular automatic calibre 324 featuring a calendar module. We can see parts of it through the exhibition caseback along with the Patek Philippe Seal and the 21k gold rotor.
