The Patek Philippe Nautilus ref. 5712R-001 is a rose gold example of the Nautilus complicated line, combining a moon-phase display, power reserve indicator, and a subsidiary seconds dial within the model's signature porthole-shaped case. This 2009 example presents a horizontally embossed dial with luminous baton hour markers, consistent with the Nautilus design language, paired with a brown leather strap and rose gold deployant elements. The dial layout places the moon-phase and date indication at 6 o'clock alongside a power reserve display above 9 o'clock and a small seconds subdial at 3 o'clock. Condition is rated excellent, and the watch is presented as a full set, including its original papers dated 2009 and an additional stylus accessory. Excellent with full set including Patek Philippe papers dated 2009 and stylus.
