Rolex Datejust 26 Platinum — White Roman Dial, 42-Diamond Bezel | Ref. 179136

Platinum is reserved for only the most prestigious configurations in Rolex's catalogue, and Reference 179136 — the Lady-Datejust 26 in platinum with a 42-diamond bezel and white Roman dial — exemplifies this hierarchy. The dense, cool-grey lustre of platinum provides an unmistakeable visual distinction from white gold, and its use throughout the case, bracelet, and bezel setting elevates this reference to the top tier of the Datejust family tree.

Powering the 26 mm case is Calibre 2236, Rolex's movement designed for the smaller Oyster case diameters. The silicon Syloxi hairspring provides improved isochronism over traditional alloys and resists magnetic interference without requiring a separate anti-magnetic shield. The 42-diamond bezel is set in a channel configuration, with stones carefully matched for uniformity. A President bracelet in platinum — traditionally reserved for flagship references — completes the presentation.

Reference 179136 is a collector's piece as much as a jewellery watch. Platinum Rolex production volumes are inherently lower than yellow or Everose gold, making original-condition examples with box and papers significantly harder to source. For buyers who understand the platinum premium and its long-term holding qualities, this Lady-Datejust offers both an exceptional wearing experience and a defensible long-term asset.
