Singer Bruno Mars spotted wearing Rolex

Bruno Mars made the cover of Rolling Stone count — not just for the music, but for the wrist. Photographed for the feature, Mars wore a Rolex Day-Date 36mm in 18kt yellow gold with a diamond-set blue gradation dial, reference 18238, a vintage piece that sits comfortably at the intersection of horological history and unapologetic luxury.

The Rolex Day-Date ref. 18238 was produced from 1988 through the early 2000s and represented the transition from the earlier ref. 18038 to the modern 118238. It houses the Rolex calibre 3155, a self-winding movement with 31 jewels, a Glucydur beryllium balance wheel, and a power reserve of approximately 48 hours — robust, accurate, and quintessentially Rolex. The 36mm case is crafted entirely in 18kt yellow gold, paired here with the iconic President bracelet, itself introduced in 1956 to mark the watch's debut. The blue gradation dial with diamond hour markers is a factory configuration, not an aftermarket modification, which is critical for value and authenticity.

Among collectors, the ref. 18238 occupies a sweet spot that the current ref. 228238 cannot fully replicate. It predates the brand's shift to larger case diameters and carries the tighter proportions that vintage purists prize. A diamond-set dial in blue gradation is among the most sought-after configurations, adding meaningful collector premium over the standard gilt or white lacquer options. Provenance and dial originality are everything with this reference.

Mars has long aligned his personal aesthetic with the golden era of American showmanship — think Vegas residencies, Motown-influenced production, and a wardrobe that skews toward tailored excess. A vintage Day-Date in full yellow gold is entirely on-brand: it is the watch of presidents, executives, and entertainers who understand that restraint is a choice, not a default.

On the secondary market, a ref. 18238 in yellow gold with a diamond dial in this condition and configuration typically trades in the $15,000–$22,000 range depending on provenance and box-and-papers status. The piece represents strong value relative to its contemporary successors, which retail considerably higher. For a watch that carries this much history, that remains a compelling proposition.
