Rapper Kim Nam-joon Rap Monster spotted wearing a Patek Philippe

Kim Nam-joon — known globally as RM, the leader and primary lyricist of BTS — was recently spotted wearing a Patek Philippe Nautilus 5712R-001, the 18k rose gold iteration of Patek's most complication-rich Nautilus reference. The sighting adds another serious horological entry to RM's growing reputation as one of K-pop's most thoughtful watch collectors, a figure who gravitates toward substance over spectacle.

Patek Philippe introduced the Nautilus 5712 in 2006, exactly thirty years after Gerald Genta's original ref. 3700 debuted at the Basel Fair. Where the core Nautilus line celebrates clean, integrated design, the 5712 loads the 40mm case with a genuine complication stack: hours, minutes, small seconds at 9 o'clock, instantaneous date, moonphase display at 6 o'clock, and a linear power reserve indicator running across the dial's lower register. The movement inside is the Calibre 240 PS IRM C LU — a micro-rotor automatic of exceptional finishing, measuring just 3.88mm in height. In the 5712R variant, the 18k rose gold case pairs with a warm black-brown dial that shifts tone under different lighting conditions, complemented by a hand-stitched brown alligator strap and a rose gold fold-over clasp.

Among collectors, the Patek Philippe Nautilus 5712R occupies rare ground: it satisfies both the integrated-bracelet sport-watch enthusiast and the complication purist simultaneously. The moonphase on the 5712 is accurate to one day's deviation every 122 years — a technical benchmark that reinforces Patek's manufacture credibility. The reference has been discontinued in several configurations, tightening supply and accelerating grey-market demand well beyond any reasonable retail anchor.

RM has been open about his interest in fine objects and design across disciplines, and his watch choices consistently reflect deliberate curation rather than trend-chasing. A 5712R in rose gold reads as a mature, confident selection — warm in tone, technically serious, and entirely recognizable to anyone fluent in haute horlogerie without requiring obvious signaling to a general audience.

At an official retail price of $51,250, the Patek Philippe Nautilus 5712R already represents a significant investment. On the current grey market, however, examples trade in the region of $200,000 — a near-quadruple premium that underscores the reference's status as both a wearable watch and a store of value. For a piece this technically accomplished and this scarce, that gulf between list and market price is unlikely to close anytime soon.
