Rolex Datejust Platinum — Silver Diamond Star Dial | Lady-Datejust 28

Platinum is the rarest and most prestigious metal in Rolex's material hierarchy, reserved for a select tier of the catalogue where ultimate refinement is the only priority. This Lady-Datejust 28 in platinum carries that distinction with assured authority — the naturally cool lustre of the metal lending the 28mm Oyster case an almost monolithic purity. The Silver Diamond Star dial is a masterclass in astronomical ornamentation: a field of silver punctuated by a star motif whose points are set with brilliant-cut diamonds, creating a timepiece that evokes both celestial grandeur and horological precision.

Calibre 2236 drives this platinum Lady-Datejust, representing a significant engineering advance over its predecessor. The 2236 incorporates a Syloxi hairspring — a Rolex-patented oscillator element manufactured entirely in-house from amorphous silicon. This material is lighter than traditional alloys, requires no lubrication at the spring-stud attachment, and offers exceptional thermal stability. Operating at 28,800 vph with a 55-hour power reserve and COSC certification, it is a movement whose technical ambition is entirely consistent with the platinum case that houses it.

For the advanced collector, a platinum Datejust commands a position at the very apex of the reference family. Platinum is used by Rolex almost exclusively in combination with the President bracelet or in special jewellery configurations, making any platinum Oyster-cased variant an object of considerable rarity. The Diamond Star dial further elevates the piece into the realm of haute joaillerie-adjacent watchmaking — a category where Rolex has historically understated its own expertise. This watch is a serious collector's acquisition, one whose combination of precious metal, gemological specification, and movement quality is unlikely to be replicated at comparable value.
