Rolex Datejust 36 Steel — Aubergine Purple Diamond Roman Dial | Ref. 126234

Revealed at Baselworld 2019, this Datejust 36 in Oystersteel introduced an aubergine dial of considerable chromatic distinction — a deep, wine-inflected purple that shifts in register from near-black at low light to a plummy violet in direct illumination. Set against the 36 mm stainless steel case with its fixed fluted bezel, the dial achieves a tension between sportif material and baroque colour that is unmistakably contemporary Rolex. Diamond-set Roman numerals at the 6 and 9 o'clock positions provide precisely calibrated gem highlights without overwhelming the dial's inherent drama.

Within the Oyster case, Calibre 3235 — introduced in 2015 and considered among the finest self-winding calibres in production — delivers approximately 70 hours of power reserve, bidirectional winding via the Perpetual rotor, and an instantaneous date change that advances in a few thousandths of a second. The Parachrom hairspring, formed from a proprietary niobium-zirconium alloy, provides tenfold greater resistance to magnetic fields than conventional springs and markedly superior shock performance. Superlative Chronometer certification attests to accuracy of -2/+2 seconds per day after casing.

A scratch-resistant sapphire crystal with double anti-reflective coating and the signature Cyclops lens magnifying the date completes the dial presentation. The Oyster bracelet in 904L Oystersteel, secured by the Oysterclasp with Easylink 5 mm comfort extension, provides both elegance and the structural integrity expected of a 100-metre water-resistant sports watch. This reference is a collector's study in how restraint and boldness can coexist within the immovable grammar of Oyster design.
