Rolex Day-Date 36 128236 Platinum Ice Blue Roman Numerals Dial (2023)

Rolex Day-Date 36 128236 Platinum Ice Blue Roman Numerals Dial (2023) pairs a diamond-set bezel with a 36mm platinum case, an ice blue roman numerals dial, and an automatic movement.

Introduced Watches & Wonders 2022, reference 128236 represents watershed moment in Day-Date platinum history—debuting platinum fluted bezel for first time after decades exclusively pairing platinum cases with smooth domed bezels on references 118206/128206. Rolex explained that until 2022, manufacturing platinum fluted bezel proved technically impossible due to platinum's challenging machining and polishing characteristics compared to gold—the metal's density and work-hardening properties requiring entirely new manufacturing processes before fluted bezel could enter platinum production. From 2022 forward, platinum Day-Date available exclusively with either platinum fluted bezel or diamond-set bezel, eliminating smooth domed bezel option that previously distinguished platinum from gold variants.

This sunray-finished ice blue shade creates cool, sophisticated aesthetic contrasting against platinum's naturally white metallic luster while Roman numerals on 36mm version feature smoother overall shape and finish versus sharper, more angular Roman numerals found on 40mm Day-Date variant. The 36mm proportions represent classic Day-Date sizing dating to 1956 original introduction, balanced diameter offering elegant wrist presence appropriate for formal dress watch positioning while 950 platinum construction provides substantial heft and density exceeding gold variants. The 36mm Oyster case measures approximately 12mm thick, executed entirely in 950 platinum with monobloc middle case ensuring structural integrity and water resistance.

Screw-down caseback and Twinlock double waterproofness system crown ensure 100-meter water resistance appropriate for presidential dress watch despite formal positioning, the Oyster architecture maintaining sports watch DNA within elegant context. Scratch-resistant sapphire crystal with Cyclops lens magnifying date aperture at 3 o'clock maintains legibility while glareproofing treatment reduces reflections. The semi-circular three-piece link President bracelet executed entirely in 950 platinum flows seamlessly from lugs, the bracelet's supple articulation and substantial weight creating luxurious wearing experience.

Concealed folding Crownclasp maintains clean aesthetic eliminating visible clasp mechanisms while Easylink 5mm comfort extension allows fine-tuning fit throughout day as wrist expands. Applied Roman numeral hour markers executed from platinum feature smoother contours on 36mm variant versus 40mm's sharper, more angular execution, filled with white luminescent material ensuring low-light legibility despite formal aesthetic. Day aperture at 12 o'clock displays full weekday name in choice of 26 languages while date at 3 o'clock benefits from Cyclops magnification, both complications featuring instantaneous midnight changeover with secure rapid-setting mechanism allowing independent adjustment without affecting timekeeping precision.

The movement achieves Superlative Chronometer certification guaranteeing -2/+2 seconds daily accuracy after casing (exceeding COSC's ±4 seconds standard), incorporating paramagnetic blue Parachrom hairspring offering superior shock and temperature resistance plus Paraflex shock absorbers protecting balance assembly. Bidirectional self-winding via Perpetual rotor ensures efficient energy transfer while Chronergy escapement patented by Rolex increases reliability and power reserve versus traditional Swiss lever escapements. The movement provides a 70-hour power reserve. The watch is driven by Caliber 3255 introduced 2015 re. Dated 2023, this example is offered in like new & unworn condition with its original box and original papers.
