Rolex Datejust 31mm two-tone 18K yellow gold and Oystersteel, reference 278243, featuring a silver sunburst dial with factory-set diamond hour markers, smooth domed yellow gold bezel, date at 3 o'clock, and the two-tone Oyster bracelet, with box and papers.

Fits 6.5 inches with 2 extra links included.  

The Rolex Datejust 31 in reference 278243 presents one of the most classically balanced expressions in the Datejust collection — the 31mm case size is the ideal proportion for a ladies dress watch that reads elegantly without overwhelming the wrist, and the smooth domed yellow gold bezel provides a clean, uninterrupted frame around the silver sunburst diamond dial. The factory-set diamond hour markers are individually set by Rolex in Geneva, with round brilliant diamonds replacing the standard baton indices at each hour position to deliver a continuous circuit of brilliance around the dial. The two-tone Oyster bracelet's alternating yellow gold center links and brushed stainless steel outer links is a combination that has defined Rolex's two-tone aesthetic since the 1970s and remains one of the most versatile and wearable luxury watch bracelet formats ever produced.
