This replica Datejust 278384RBR pink is a 31mm mid-size reference from the current ladies Datejust range. The 278384RBR designation indicates diamond-set bezel on an Oystersteel case, with the pink dial providing a warm, feminine tone against the brilliant-cut stones. At 31mm, this sits between the 28mm Lady-Datejust and the 36mm unisex Datejust, offering a size that works for wrists that find the 28mm too small but the 36mm too sporty. The diamond bezel adds a permanent sparkle border that elevates the watch beyond standard steel configurations.

Case & Movement Specs

• Case diameter: 31mm
• Case material: Oystersteel
• Bezel: diamond-set, brilliant-cut stones
• Dial: pink
• Crystal: sapphire with Cyclops magnification

The 278-series references replaced the older 178-series with updated case construction and movement architecture. The diamond bezel uses individual brilliant-cut stones set into channels around the full circumference, and the count and carat weight remain consistent across all 278384RBR variants regardless of dial color.

Caliber Breakdown

Inside this 31mm case sits the caliber 2236, which introduced a silicon Syloxi hairspring to the Rolex ladies lineup. Silicon is paramagnetic and resistant to temperature variations, which improves rate stability compared to earlier metal hairspring calibers. The 55-hour power reserve is shorter than the 70-hour figure on the men’s 3235 but adequate for weekend storage. A ladies rolex datejust with diamond bezel combines jewelry-level finishing with genuine tool-watch specifications: screw-down crown, 100 meters of water resistance, and an Oystercase monobloc middle case. Compare the pink dial against the 126334 mint dial in 41mm, or browse the Datejust collection for other sizes and dial options.

How It Compares

The 31mm sweet spot gives the 278384RBR an audience that neither the 28mm nor 36mm references fully address. The diamond bezel adds formality without requiring a precious-metal case, keeping the overall weight manageable for daily wear. Pink dials in this size tend to lean feminine without crossing into overtly decorative territory because the steel case and Jubilee bracelet maintain a balanced proportion. The combination of diamonds, pink, and mid-size dimensions makes this reference a popular choice among buyers seeking a Datejust that scales appropriately for smaller wrists. This replica Datejust 278384RBR pink puts that precise sizing and diamond bezel together in a configuration that the men’s lineup simply does not offer.
