Rolex Datejust 36 Yellow Rolesor — White Roman Dial | Ref. 116243

Reference 116243 represents the Datejust 36 at its most classically Rolex — a composition built on the Rolesor concept first introduced in the 1930s, here realised in yellow gold and Oystersteel. The 36 mm diameter inhabits the precise proportional ideal that underpinned the Datejust's original 1945 design brief, and this example honours that legacy without revision. The 18K yellow gold bezel is set with 52 brilliant-cut diamonds in a pavé arrangement, the warm gold prongs drawing out the stones' fire in a manner that an all-steel setting cannot replicate.

The white dial carries Roman numerals rendered in sharp relief, a traditionalist choice that aligns the watch with the patrician formality the Datejust was conceived to serve. Roman numerals on a white dial speak to the boardroom and the black-tie occasion equally, and this combination has been among the longest-running configurations in the Datejust catalogue. The date window at three o'clock, amplified by the Cyclops lens integrated into the scratch-resistant sapphire crystal, provides the functional dimension that separates a Datejust from a purely aesthetic exercise.

Beneath the screw-down caseback sits the Calibre 3135, the self-winding movement that serves as the backbone of the Datejust 36 generation to which this reference belongs. Equipped with a Parachrom hairspring in blue paramagnetic alloy, the calibre offers 10 times greater resistance to shocks than a conventional spring and is unaffected by magnetic fields. Approximately 48 hours of power reserve and a rapid-setting date mechanism complete the specification. The Oyster bracelet in Yellow Rolesor — flat three-piece links alternating steel and gold — is fastened by an Oysterclasp for secure, tool-free adjustment.
