Design & Build
This model features the classic rounded-octagonal shape of the case inspired by the porthole design concept created by Gérald Genta, with the 40.5mm size providing a nice balance between visibility and compactness.
The combination of brushing and polishing finishes creates an interesting contrast between the metal surfaces, with the angular shapes of the watch case accentuated in such arrangement.

Rather than using the traditional metal bracelet, this watch is fitted with the black rubber strap, giving it the sporty look and contrast with the metallic case and silver-white dial.
Dial Details
The silver-white dial is one of the most prominent features of this particular model, with the classic horizontal embossed pattern characteristic of the Nautilus aesthetic applied to it. It provides some texture to the face and at the same time allows the numerous calendar indications not to get lost in its complexity.
There are day and month display windows located at 12 o’clock and date indication at 6 o’clock. All the indications are placed in such a way to form the composition around the 24-hour indication and blue-toned moon-phase display.
Blackened-gold-tone hour markers and hands provide contrast with the light dial, while their luminous finish ensures high legibility in low light conditions.
Movement & Performance
The Clone Caliber 324 S QA LU 24H/303 is used as a power source for this watch – an automatic mechanical movement that can be used to display all the calendar indications and moon-phase.
As a combination of the day, month, date, 24-hour indication and moon-phase functions along with the movement, it allows this model to have a characteristic calendar-oriented dial arrangement. As an automatic mechanical watch, it is intended for enthusiasts who prefer the mechanical timepiece to the battery-operated one.
Being equipped with sapphire crystal and having 30 meters of water resistance, the watch is best suited for everyday wear and ordinary activities rather than swimming.
Calendar & Moon-Phase Display
One of the most characteristic features of the Patek Philippe Nautilus 5726/1A-010 replica is its combination of the calendar indications with the moon-phase display.
The presence of day and month windows at 12 o’clock indicates the calendar nature of this watch. Meanwhile, the date display at 6 o’clock serves as a good counterbalance to this feature. The dial around the 24-hour indication contains a blue-toned moon-phase disc, providing some additional decoration for the silver-white dial.
The watch does not use a simple three-hand configuration but rather makes full use of the dial space.

Lifestyle & Wearing Experience
The combination of a stainless steel case and black rubber strap makes this model very versatile. It can fit well both with casual shirts, polo shirts, knitwear and denim and other contemporary everyday clothing, as well as with the business-casual attire.
The 40.5mm case provides a noticeable wrist presence without being too oversized for a sports watch. The rubber strap, in turn, makes the overall combination visually lighter than a full stainless steel bracelet arrangement.
For everyday wear, the silver-white dial provides a lot of versatility. Its light base allows for easy pairing with neutral clothing, while the blue moon-phase adds a touch of color to the otherwise monochromatic design.
