This reference expands beyond timekeeping with a multi-complication display housed in a stainless steel case. The asymmetrical dial presents a moon phase indicator, power reserve display, small seconds, and date subdial, each carefully positioned to maintain visual harmony. The automatic movement beneath drives these functions with precision, supported by a finely finished rotor visible through the sapphire case back. The bracelet maintains the Nautilus signature integration, ensuring both durability and comfort.

Rather than symmetry, this model embraces character. It appeals to collectors who value mechanical storytelling on the dial, offering a more technical interpretation of the Nautilus without sacrificing its iconic silhouette.

Alternative References

The broader 5712 family includes:

* 5712/1A-001 — stainless steel, blue dial and stainless-steel bracelet.
* 5712G-001 — white gold.
* 5712R-001 — rose gold.
* 5712GR-001 — combination of rose gold and white gold.
* 5712T-001 — special titanium execution.

The 5712/1A-001 is therefore specifically the stainless-steel bracelet version.

Reference Distinction

The 5712/1A-001 is substantially more complicated than the 5711. Its defining characteristic is the asymmetrical dial architecture, combining four indications around the dial while retaining the thin, integrated-sports-watch profile. Patek Philippe’s Nautilus history identifies the 5712 as one of its complication models, while auction documentation confirms the stainless-steel 40 mm configuration and Calibre 240 PS IRM C LU.
