Rolex assigned the 228-prefix to its latest Day-Date generation, signaling a new movement platform and refined case construction. The 228239 in mother of pearl takes that modernity and wraps it in the most organic dial material available — each piece of nacre reflecting light in patterns impossible to replicate identically. This replica captures the reference’s updated proportions while delivering the iridescent visual signature that has made MOP dials perennial favorites.

The 228239 Up Close: Case, Dial and Bracelet
The 228239 case shares the 36mm diameter of its Day-Date predecessors, but benefits from refined lug geometry introduced with the 228-series. The fluted bezel in yellow gold catches light from its sharply defined ridges, directing attention toward the mother of pearl dial below. Diamond hour markers sit against the nacre background, each catching and scattering light independently.
The three-link President bracelet maintains Rolex’s distinctive presidential identity, with a concealed Crown clasp for an unbroken line around the wrist. View all available Day-Date references in the Day-Date collection.
Movement Options: Swiss vs Japanese

- Swiss Automatic — 3255-series caliber operating at 28,800 vph, with approximately 70-hour power reserve. Instantaneous day-date change at midnight, hacking seconds for synchronization.
- Japanese Automatic (Miyota) — Running at 21,600 vph with ~42-hour reserve. Proven reliability across temperature variations and daily wear conditions.
Each option incorporates bidirectional winding and quickset for both day and date adjustment.
