Mother of pearl has appeared on Rolex dials for decades, but no two pieces are ever identical — each shell section carries its own pattern of iridescence, meaning every 178274 has a subtly unique dial. At 31mm, this reference occupies the middle ground between the petite 26mm and the larger 36mm, offering a size that works across a wide range of wrist types. Combined with diamond hour markers and a fluted white gold bezel, it delivers quiet luxury with an organic twist.

The 178274 Up Close: Case, Dial and Bracelet
The white mother of pearl dial shifts between cool silvery tones and warmer pink-green iridescence depending on the angle and lighting. Diamond hour markers sit directly on the shell surface, adding points of brilliance that catch light alongside the natural shimmer of the nacre. A date aperture at three o’clock is magnified by the Cyclops lens for quick reference.
At 31mm, the case strikes a balanced proportion — substantial enough to read easily, yet compact enough for elegant wrist presence. The Jubilee bracelet with its five-piece links drapes softly and tapers toward the concealed Crownclasp. Browse the full range of mother of pearl dials in the Lady-Datejust collection.
