Description
At the heart of the Rolex Datejust 278288RBR beats the caliber 2236, a superlative chronometer movement that represents Rolex’s latest generation of automatic mechanisms, powering this 31mm yellow gold case with precision that collectors have come to expect from the manufacture. The silver diamond dial creates a sophisticated contrast against the warm 18k yellow gold construction, while the diamond-set bezel elevates this reference beyond the standard Datejust offerings. This particular 278288RBR configuration showcases Rolex’s mastery of proportions in the smaller case size, delivering the iconic Datejust aesthetic with contemporary refinements including the Chronergy escapement and Paraflex shock absorbers that define modern Rolex engineering.
