Built around the 5711/1A-018 reference, this replica nautilus 57111A black 40mm 018 puts a black dial behind the signature octagonal bezel on a 40mm stainless steel case. The horizontal embossing across the dial surface creates a ribbed texture that shifts between matte and reflective as light moves across it. Gerald Genta designed the Nautilus as a luxury sports watch that could transition from a yacht deck to a boardroom, and the black dial variant leans further into the formal end of that spectrum than the iconic blue.

Key Specifications

• Case diameter: 40mm
• Case material: stainless steel
• Dial: black with horizontal embossed pattern
• Bezel: octagonal polished surround
• Bracelet: integrated stainless steel with fold-over clasp
• Movement: automatic
• Functions: hours, minutes, seconds, date

The bracelet links taper gradually from lug to clasp, following the same curved geometry that defines the case profile. Alternating brushed and polished finishing on each link adds visual rhythm to the steel surface.

Design & Finishing

Black on steel produces a higher contrast ratio than the blue or white dial options, which makes the applied hour markers and hands stand out more sharply. The date window at three o’clock is framed to match the surrounding embossed texture, keeping the dial face visually unified. Patek Philippe positioned the 5711/1A as the core Nautilus reference, and black sits alongside blue and white as one of its defining dial options. Compare this against the rubber strap variant for a sportier take on the same case and dial combination. The full Nautilus lineup spans from time-only references to chronograph and perpetual calendar complications.

Who It’s For

The 5711/1A in black serves collectors who want the Nautilus silhouette without the visibility of the blue dial. It pairs equally well with a dark suit or weekend linen. The 40mm case sits flat against the wrist thanks to integrated lugs that eliminate the gap between case and bracelet. This replica nautilus 57111A black 40mm 018 captures the understated authority of a steel Nautilus in its most discreet color configuration.
