The 178274 reference positions this replica diamond 178274 as a 31mm Lady-Datejust with a white mother of pearl dial that shifts between soft pink, green, and silver depending on the angle of light. Mother of pearl dials are inherently unique because no two shells produce identical patterns, and Rolex has historically selected the most uniform sections for their Lady-Datejust production. At 31mm the case bridges the gap between the original 26mm ladies’ size and the 36mm unisex standard, giving it a presence that works across formal and everyday settings.

Technical Overview

• Case diameter: 31mm
• Case material: Oystersteel
• Bezel: fluted white gold
• Dial: white mother of pearl
• Crystal: sapphire with Cyclops magnification
• Bracelet: Jubilee five-link stainless steel
• Movement: automatic with date

The white gold fluted bezel paired with the Oystersteel case creates a subtle contrast that avoids the overt flash of a full two-tone build. This combination keeps the watch understated while still signaling a step above an entirely brushed-steel configuration.

Inside the Movement

The 178274 runs an automatic caliber with instantaneous date change at midnight. The date window at 3 o’clock sits beneath the Cyclops lens, which magnifies the numeral by 2.5 times for readability. Day-to-day accuracy remains consistent across typical wrist motion. For those drawn to the Lady-Datejust platform but wanting diamond-set bezels and precious metal bracelets, the Pearlmaster 31mm silver reference offers a more ornate alternative within the same diamond watches lineup. The Pearlmaster shares the 31mm diameter but swaps the Jubilee for its signature rounded-link bracelet.

What Sets It Apart

Mother of pearl dials make every 178274 visually distinct. Where a standard sunburst dial reflects light in predictable radial lines, the nacre surface on this reference creates an organic iridescence that changes character throughout the day. The 31mm case size has become the preferred ladies’ format for Rolex in recent years, offering legibility without overwhelming slender wrists. As a full-steel piece with a white gold bezel accent, this replica diamond 178274 delivers dressy sophistication with daily-wear durability.
