Dear All,
After putting this beauty on wrist for nearly a week, would like to share with you my feeling towards it.
1. The blue dial is indeed amazing, showing different shades of blue according to the ambient lighting. The dial layout is also balanced and symmetrical, with bilateral sub-dials right at the 3hr and 9hr levels. The number of the date subdial at 6hr position also has no distortion of the numbers.

2. Being the thinnest Patek perpetual calendar (8.42mm, even thinner than 5712), it sits on the wrist with a low profile, almost sticking to skin.


4. There is a new deflector system moving the correctors on both sides of the case towards the lug holes (except the one at 9hr position), without interrupting the nautilus case design. This is a unique feature, not seen in other nautilus with correctors (e.g. 5712, 5726). It is a subtle, yet remarkable design, as the correctors are not placed in the most direct/ shortest distance from the caliber inside, which isn't easy to achieve.



The Patek Philippe Reference 5726 represents a significant milestone in the manufacture s annual calendar collection, combining the practical sophistication of an annual calendar with a sleek nautical aesthetic. Introduced as part of Patek Philippe s modern sports-elegant lineup, this reference demonstrates the brand s mastery in creating complicated timepieces that maintain everyday wearability. The 5726 builds upon Patek Philippe s rich heritage of calendar complications, offering collectors a contemporary interpretation of haute horlogerie that bridges the gap between dressy complications and contemporary sports watches.
At the heart of the Reference 5726 beats the exceptional Caliber 324 S QA LU 24H/303, an automatic movement that showcases Patek Philippe s technical prowess in calendar mechanisms. This sophisticated caliber features an annual calendar complication that automatically adjusts for months with 30 and 31 days, requiring manual correction only once per year at the end of February. The movement incorporates a 24-hour indication alongside the traditional calendar functions, displaying day, date, month, and moon phases through elegantly arranged subsidiary dials. The self-winding mechanism ensures consistent power delivery while maintaining the thin profile necessary for the watch s refined proportions.
The 40.5mm stainless steel case presents a contemporary interpretation of classic Patek Philippe design language, featuring clean lines and perfectly executed finishing that exemplifies the manufacture s attention to detail. The striking blue sunburst dial creates remarkable depth and luminosity, with its rich color serving as the foundation for the symmetrically arranged calendar displays. Protected by a sapphire crystal and featuring a fixed smooth bezel, the 5726 balances functionality with aesthetic refinement. For collectors, this reference represents an accessible entry point into Patek Philippe s complicated watch segment while offering the prestige and technical excellence associated with one of horology s most revered manufacturers. The combination of stainless steel construction, practical complications, and distinctive design elements positions the 5726 as a highly desirable piece for both seasoned collectors and those building their first serious watch collection.
Glad you are enjoying this new addition. Your 5131P must be envious ! 🤣
Love the blue dial Henry , and to see you enjoy this so much Cheers Robin
Yes, I enjoy the 5740G a lot. It weighs just right and has a svelte appearance. Initially I am thinking of keeping it in brand new condition in the case for a longer period of time, but eventually could not resist the temptation of putting it on wrist. Best, Henry
A beauty. The best Nautilus. My opinion. 👏 😊 Geross.
Time flies. Miss those days when I had more time for the hobby Cheers Robin
Perpetual calendar has a special meaning to me, it was my most wanted complication when I started collection of serious watches. Best, Henry
