Rolex Datejust 31 Yellow Gold — Paved Mother-of-Pearl Butterfly Dial | Ref. 278248

Reference 278248 is among the most artistically ambitious expressions of the Datejust 31 — a 31 mm case in 18 ct yellow gold housing a dial that describes itself in its specification: paved mother-of-pearl with a butterfly motif. Rolex's dial artisans source nacre from natural shell material and arrange it in sections to create the butterfly pattern, a technique that demands both precision and an eye for the organic variation inherent in the material. The result is a dial that functions as a miniature work of applied art, framed by a yellow gold Oyster case that provides warmth and contrast to the cool iridescence of the pearl.

Calibre 2236 drives the 278248. Introduced to replace the 2235, this movement features a Syloxi silicon hairspring — an advancement that improves antimagnetic performance and reduces the effects of temperature variation on timekeeping accuracy. At 28,800 vph with a 55-hour power reserve, it represents the current standard for Rolex's mid-size manufacture calibres. The 31 mm yellow gold case is waterproof to 100 metres and polished to the fine finish standards expected of a precious-metal Datejust. The bracelet pairing for this reference typically complements the case material in yellow gold.

The butterfly motif dial belongs to a family of decorative Datejust configurations that occupy a distinct collector niche — pieces that prioritise dial artistry as much as horological credentials. These references are produced in limited quantities relative to index-dial variants and command premiums in the pre-owned market commensurate with their dial complexity. For the collector interested in Rolex's less-publicised but genuinely skilled dial craft, the 278248 represents an accessible entry point into motif-dial collecting, with the added security of a current-generation calibre and the Datejust's enduring market liquidity.
