Patek Philippe‘s exhibiting at Watches and Wonders this yr was one among its most formidable in current reminiscence. A lot in order that they took dwelling the excellence of being the Maison with the biggest variety of references launched on the honest—with over 20.
They showcased a quartet of Nautilus anniversary editions and introduced updates to the Calatrava and the Golden Ellipse. They zeroed in on excessive horology, introducing the Celestial with a dawn and sundown show, in addition to a few new perpetual calendars—which brings us to the primary spotlight of the novelties: the brand-new Cubitus Perpetual Calendar.


The 5840P kicks off the Cubitus’ foray into grand issues with a perpetual calendar, and it’s offered throughout three subdials conveying the date, day of the week, month, moon phases, and leap years. Designed to run for many years with out requiring guide changes to account for various month lengths and leap years, the wedding between a perpetual calendar and the Cubitus makes good sense—particularly so since everybody appears to be taking care of their Patek Philippe with the subsequent era in thoughts.


The moonphase show right here is especially fascinating. It breaks with the conference of the standard moonphase show, which employs a small dial aperture and a rotating disc with two moons to obscure parts of the moon. So as to create a more true depiction of the moon, Patek Philippe has opted to make use of only one massive, photorealistic moon that completes a single full rotation for each lunar cycle, reasonably than two.
The principle draw of this watch, nonetheless, is one thing that requires little or no shut inspection to note. It’s the shutter shades, the Cubitus now has a skeletonised dial. Very like its unconventional moonphase show, that is completed so with out conforming to expectations. The long-lasting horizontal ribbed sample discovered on the dials of the Nautilus and Cubitus is replicated right here by way of the shades, that are achieved by way of exact laser chopping.

This permits glimpses into the ultra-thin self-winding calibre 28-28 Q SQU motion, which has tailored solely to the squared form of the Cubitus. It builds upon the earlier calibre 240 Q, which was round and left a substantial quantity of unused house throughout the case. You’ll admire this greatest once you flip the watch over and consider it by way of the ribbed caseback. The totally monochrome rhodium-plated motion is punctuated by heat-blued screws and a microrotor bearing hand-engraving of the Calatrava motif, additionally completed in blue.
From the entrance to the again, the 5840P’s mechanical coronary heart is encased inside a ribbed cage, which actually lends its designation as a skeletonised watch a completely new that means.

Aside from these updates, every part else stays largely the identical—the identical curved but angular edges on the sq. case, and the identical 45mm diameter, although this iteration measures barely thicker at 10mm in comparison with the earlier 9.6mm. There are not any variations of this reference, only a platinum case set with a baguette-cut diamond within the bezel at 6 o’clock.
