Rolex Datejust Yellow Rolesor — Silver Index Dial | Ref. 116243

Reference 116243 in Yellow Rolesor with a 52-diamond cut bezel offers one of the Datejust 36's most balanced expressions of gemstone luxury within a bicolour framework. The 18-carat yellow gold bezel — set with brilliant-cut diamonds across its entire circumference — rests atop a 904L stainless steel case whose satin-brushed flanks and polished bevels maintain the precise geometry that has distinguished the Oyster case since 1926. Against this diamond-set yellow gold crown, the silver dial with applied index hour markers reads with clear, uncluttered elegance, the warmth of the yellow gold markers and hands introducing tonal coherence between bezel and dial.

Calibre 3135, the workhorse self-winding movement of the Datejust 36's modern production era, anchors the 116243 with chronometric dependability. Its bidirectional rotor oscillates to wind the mainspring through the natural motion of the wrist, while the Parachrom hairspring — produced in-house from a paramagnetic niobium-zirconium-oxygen alloy — provides a hairspring isochronism largely immune to magnetic disturbances typical of everyday environments. The movement is COSC-certified, with Rolex's own quality controls pushing individual rate deviations well below the ±4 seconds per day limit required for official chronometer designation.

The five-piece Jubilee bracelet in Yellow Rolesor — polished yellow gold centre links flanked by steel outer links — was purpose-designed for the Datejust in 1945 and remains the most jewellery-like bracelet in the Oyster stable. Its articulated construction fits the wrist with a suppleness absent from the stiffer Oyster bracelet, making the 116243 a natural companion for extended daily wear. Water-resistant to 100 metres and carrying the Superlative Chronometer designation, this reference unites precision engineering, yellow gold warmth, and diamond brilliance in a proportion — 36 mm, Jubilee bracelet, silver dial — that has remained quietly definitive within the Datejust family for generations.
