Rolex Datejust White Gold — 48-Diamond Bezel Mother-of-Pearl Roman Dial | Ref. 178159

Reference 178159 represents the white gold apex of the Datejust 31 — a configuration that combines an 18 ct white gold Oyster case with a diamond-set bezel of 48 individual brilliant-cut stones and a mother-of-pearl dial bearing Roman numeral hour markers. The result is a watch that inhabits the boundary between timepiece and high jewellery. The mother-of-pearl dial surface, with its characteristic iridescence, provides depth and luminosity that complements the cold brilliance of the surrounding diamond bezel, while the Roman numerals add a layer of classical dignity that anchors the composition in watchmaking tradition.

Calibre 2235 — the predecessor to the current 2236 — provides the movement for this 31 mm Datejust. The 2235 is a self-winding manufacture calibre featuring a Parachrom hairspring produced from Rolex's proprietary paramagnetic alloy, which offers ten times greater shock resistance than conventional steel hairsprings and is unaffected by magnetic fields. The movement achieves COSC chronometer certification and delivers a 48-hour power reserve, appropriate for a watch in this size category. Rolex's proven track record with the 2235 across decades of production speaks to its engineering maturity.

Reference 178159 occupies a distinguished position within the secondary market for its combination of white gold, diamond bezel, and natural dial material. The 48-diamond bezel is among the more substantial gem-setting programmes applied to the Datejust 31, while white gold's cool, platinum-adjacent appearance gives the case a formality that yellow or rose gold cannot replicate. For collectors assembling a curated selection of jewellery watches, this reference delivers a level of finish and material quality that stands comparison with dedicated haute joaillerie pieces from Geneva's most prestigious maisons.
