Nearly black in low light, the blue-black gradient dial of this Patek Philippe Nautilus 5711/1A-010 replica turns deep blue in daylight, framed by brushed stainless steel. At 40mm, this Nautilus 5711/1A-010 super clone presents the Nautilus in its classic form. The blue-black dial with horizontal embossing shades from a lighter blue centre to a near-black rim, the gradient Patek gave the 5711/1A-010, and it gives this steel Nautilus the look that made the reference famous. Stainless steel construction keeps the weight moderate while the integrated bracelet maintains the signature Nautilus wrist profile that has remained essentially unchanged since 1976. Our breakdown of the blue-black gradient of the 5711/1A-010 dial explains how dark the rim should get compared with the centre.

The blue-black dial is the core of the 5711 family. Where the green variant plays with light, this gradient pulls it toward the darker rim, creating higher contrast against the applied baton hour markers.

What Sits Behind the 5711/1A-010 Caseback

The clone Cal. 324 SC visible through the sapphire caseback provides standard time-and-date functionality, and the case follows the slim lines of the genuine, which stays under 9mm thick. Patek Philippe engineered the Nautilus case to integrate seamlessly with the bracelet, so the transition from case to link is invisible from the side. The brushed-and-polished finishing pattern on the bracelet remains consistent with other steel 5711 variants, and the blue-black dial keeps the overall impression balanced between sport and dress. For a Nautilus with added complications, the white 5726/1A-010 with annual calendar and moon phase adds mechanical depth at a slightly larger 40.5mm diameter. Both share the Nautilus DNA, but the 5726 trades simplicity for functionality.

The Gradient That Defined the 5711

Blue-black dials tend to photograph darker than they appear in person. Under direct light the horizontal embossing reveals itself as a subtle texture across the face, preventing the dial from looking flat. The date window at 3 o’clock features a recessed frame that matches the dial color, and the applied baton indices with luminous fill provide sharp legibility against the dark background. This 5711/1A-010 super clone offers the reference in the gradient that first made it famous, on a steel case and bracelet.
