Rolex Steel and Yellow Gold Datejust 31 Watch - Domed Diamond Bezel - Silver Diamond Dial - Oyster Bracelet - 278343 sdo

At the heart of the Rolex Datejust 278343 beats the caliber 2236, a self-winding movement that represents Rolex's latest generation of women's complications, delivering the brand's coveted Superlative Chronometer certification with accuracy to -2/+2 seconds per day. This 31mm yellow gold case configuration strikes the perfect balance between the traditional 26mm and sportier 36mm variants, housing a silver diamond dial that catches light through ten brilliant-cut diamond hour markers. The domed diamond bezel elevates this reference beyond standard fluted or smooth bezels, creating a sophisticated interplay of light that complements the Oystersteel and yellow gold Rolesor construction. Reference 278343 represents Rolex's commitment to precision engineering in a distinctly feminine package, combining the robustness of the Oyster case with the elegance expected from the Datejust lineage.
