Rolex Datejust 26 Platinum — Ice Blue Diamond Dial with 42-Diamond Bezel | Ref. 179136

Platinum is one of the rarest case materials in Rolex's catalogue, and reference 179136 — the Datejust 26 in solid platinum — represents a pinnacle expression of the smallest Datejust case size. At 26 mm, this is a watch conceived for fine dress use, its proportions calibrated for formal occasions rather than everyday wear. The 42-diamond bezel encircles the case in brilliant-cut stones set in a continuous channel, while the ice blue dial — a colour Rolex reserves exclusively for platinum-cased references — carries diamond hour markers that register as bright points of light against the cool, luminous ground. Ice blue dials cannot be requested in any other metal, making platinum ownership the only path to this specific aesthetic.

Driving the 179xxx Datejust series is a movement from the Calibre 2235 family, Rolex's self-winding calibre engineered for the ladies' Datejust range. It features a bidirectional rotor, quickset date, and Parachrom Bleu hairspring for magnetic resistance and thermal stability. Superlative Chronometer certification ensures accuracy within ±2 seconds per day. The platinum Oyster case delivers 100 metres of water resistance through its screw-down Twinlock crown and solid caseback. Platinum's natural density gives the case a distinctive wrist feel — heavier and cooler to the touch than gold or steel.

Platinum Rolex references occupy the thinnest layer of the secondary market, with supply consistently constrained by their initial rarity in production. The 179136's diamond bezel and ice blue dial combination is the most sought-after configuration in this size — a piece that functions simultaneously as a fine watch, a jewellery item, and a tangible store of value. Buyers entering this segment are rarely disappointed by resale liquidity.
