Rolex Day-Date 36 Platinum — Bright-Blue Diamond-Set Dial | Ref. 128396TBR

Few configurations of the Day-Date command as much attention as reference 128396TBR, which pairs a solid platinum case with a vivid bright-blue diamond-set dial and a diamond-encrusted bezel. Platinum is the rarest metal offered in the Day-Date lineup and carries its own subtle distinction: Rolex marks the model's President bracelet clasp with a special fluted motif reserved exclusively for the precious metal, and only the platinum variant receives the blue lacquered dial as a standard option — though this example goes further with a diamond-set version.

At the heart of the watch sits Calibre 3255, the manufacture movement that underpins the current Day-Date 36. Its architecture includes a Chronergy escapement, a Parachrom hairspring in a proprietary paramagnetic alloy, and a 70-hour power reserve — benchmarks that far exceed the historical standard for this size class. The platinum President bracelet is finished to Rolex's exacting standards, with alternating polished centre links and brushed outer links that catch light at every angle.

Platinum Day-Date references consistently occupy the upper tier of the secondary market given their limited production relative to gold variants. The 128396TBR with its bright-blue dial sits in a category that appeals equally to royalty, heads of state, and serious horological collectors. Presented complete with box and papers from 2024, this is an essentially unworn example of one of the most desirable configurations in the entire Rolex catalogue.
