Rolex Lady-Datejust 26 Yellow Gold — Meteorite & Diamond Dial | Ref. 179178

Reference 179178 is a Lady-Datejust in 18k yellow gold that pairs one of watchmaking's most singular dial materials — meteorite — with factory-set diamond hour markers and a fluted yellow gold bezel. Meteorite dials, cut from the Gibeon meteorite found in Namibia, display the distinctive Widmanstätten pattern formed over billions of years of slow crystallisation in space; no two dials are identical. Combined with the geometric precision of diamond indices and the warmth of yellow gold, the result is arresting.

The 26mm Oyster case houses Rolex's Calibre 2235, the in-house movement developed for the Lady-Datejust, delivering date display and a power reserve appropriate for everyday wear. The President bracelet in 18k yellow gold — semi-circular three-piece links with a concealed clasp — was introduced alongside the Day-Date in 1956 and remains exclusive to Rolex's fully precious-metal references. Its comfort and security are benchmarks for precious-metal bracelet design in the industry.

Meteorite-dial Rolex references represent an intersection of geological rarity and horological craft that resonates with both watch collectors and jewellery buyers. The 179178 in this configuration — yellow gold case, fluted bezel, President bracelet, diamond indices — is a complete and self-consistent expression of the Lady-Datejust's luxury proposition. For collectors with an interest in unusual dial materials, this reference is genuinely irreplaceable: the material simply cannot be replicated.
