Rolex Datejust 31 Yellow Rolesor — Champagne Jubilee Diamond Dial, Diamond Bezel | Ref. 178343

Among the mid-size Datejust references, 178343 represents a full jewellery specification that Rolex positioned at the intersection of precision timekeeping and gem-set artistry. The 31 mm Oyster case is rendered in Yellow Rolesor, with a factory-set diamond bezel accommodating 24 individual stones, and a champagne dial displaying hour markers individually set with diamonds in Jubilee configuration — a layout that uses larger stones at twelve, three, six, and nine.

The movement is Calibre 2236, Rolex's dedicated mid-size ladies' calibre featuring the Syloxi silicon hairspring for superior resistance to magnetic fields and temperature fluctuation. Running at 28,800 vph with a 55-hour power reserve, it is COSC-certified as a Superlative Chronometer. The Oyster bracelet in Yellow Rolesor continues the two-tone motif across three rows of alternating steel and gold links.

Reference 178343 speaks to buyers investing in a watch that functions simultaneously as fine jewellery. The champagne Jubilee diamond dial is among the more desirable configurations within this reference range, as the warm tone of the dial harmonises naturally with the yellow gold elements. Well-preserved examples with original papers attract serious attention from collectors who prize the factory gem-set integrity over aftermarket modifications.
