Rolex Datejust 29 White Gold — Black Diamond Dial, 116-Diamond Bezel | Ref. 80339

Reference 80339 belongs to the earlier Datejust 29 generation — a 29 mm case size that predates the current Datejust 28 nomenclature. In 18-carat white gold, with a 116-diamond bezel and a black diamond dial, this reference sits at the maximum jewelled specification achievable in the configuration. The black dial, set entirely with diamonds in a pavé or bead-set arrangement, creates an extraordinary optical effect — the surface absorbs ambient light at depth while the diamonds return it as localised brilliance, shifting the perception of the dial between solid black and active sparkle depending on the light source.

Calibre 2235 powers the watch, the earlier-generation Rolex manufacture movement for this case size. Its self-winding mechanism, Parachrom hairspring, and Paraflex shock system provide robust timekeeping in a compact movement architecture appropriate for the 29 mm case. The Oyster case provides 100 metres of water resistance. With 116 diamonds in the bezel, the total gem count on this reference is exceptional by any standard, requiring extraordinary precision in stone selection and setting to maintain the uniform appearance critical in high jewellery watch work.

In the secondary market, white gold Datejust references with black diamond dials and maximum diamond bezels occupy a specific niche: buyers looking for an evening watch of genuine substance, where the gem count and precious metal together justify a price point above standard diamond-bezel variants. Reference 80339 in fine condition is a relatively scarce find, as pieces at this specification level are produced in limited quantities and tend to remain with original owners for extended periods before re-entering the market.
