Patek Philippe Nautilus 5726 Grey Dial Black Rubber Strap
Original price was: $1,699.00.$999.00Current price is: $999.00.
This Nautilus 5726 pairs a gradient grey embossed dial with an integrated black rubber strap and deployant clasp in a 40.5mm 904L stainless steel case. It runs on the PPF modified Clone 324 with functional day, date, month, 24-hour, and moonphase displays, plus a sapphire crystal with colorless AR coating.
5726 annual calendar layout with grey embossed dial
This Nautilus 5726 is built around the annual calendar display that defines the reference. The gradient grey dial uses horizontal embossing and a metallic sunburst effect, with recessed sub-dials that organize the calendar information cleanly across the face. Day, date, month, 24-hour indication, and moonphase are all active, giving this watch the full visual and mechanical character of the 5726 configuration.
The dial presentation stays true to the reference’s more technical side. The grey tone shifts across the surface as light moves over the embossed pattern, while the display layout keeps the calendar and moonphase functions central to the watch rather than treating them as secondary details. For buyers looking specifically for the annual calendar Nautilus format, that combination is the point of this build.
40.5mm 904L steel case and fixed steel bezel
The case is produced in solid 904L stainless steel and follows a 40.5mm profile with 47mm lug-to-lug and 11.3mm thickness. The construction uses the integrated bezel and mid-case layout associated with this model, giving the watch the correct proportions for the annual calendar reference. At approximately 115 grams, it brings the steel case and rubber strap combination into a more versatile format than a full metal bracelet execution.
The fixed bezel is also 904L steel, finished with a brushed top surface and polished chamfered edges. Alternating brushed and polished surfaces continue across the exterior, which gives the watch the contrast expected from this reference without crowding the overall design. The case also includes the recessed corrector pushers used to adjust the calendar functions.
PPF modified Clone 324 with full calendar functions
Power comes from the PPF modified Clone 324, built with a custom module to drive the complications used here. The movement supports hours, minutes, central seconds, day, date, month, moonphase, and a 24-hour display. This is the core of the watch: a Clone 324 architecture configured specifically for the annual calendar layout rather than a simple time-and-date setup.
The modular complication structure also explains the watch’s approximately 36-hour power reserve. Functionally, the movement is designed around the complete calendar display and the corrector pusher layout on the case flank, so the mechanical story and the external construction line up with each other. For a buyer focused on this specific Nautilus reference, that matters more than generic movement branding.
Black rubber strap, deployant clasp, sapphire crystal
This version is fitted with an integrated black rubber strap that meets the case with tight lug tolerances and closes with a deployant clasp. The strap changes the character of the 5726 from a bracelet-led presentation to something more casual and more flexible in day-to-day rotation, while keeping the annual calendar display at the center of the watch.
Over the dial, the watch uses a scratch-proof sapphire crystal with colorless AR coating. That keeps the focus on the dial texture, calendar apertures, and moonphase display without adding unwanted tint. Taken together, the grey dial, steel case, rubber strap, and full complication set make this a very specific 5726 configuration with a clear identity of its own.
