Rolex Day-Date Yellow Gold — Fluted Bezel Blue Diamond Dial | Ref. 118238

Among the most celebrated expressions in the Rolex canon, the Day-Date 36 in 18ct yellow gold occupies a singular position as the original prestige watch — the reference worn by presidents, heads of state, and luminaries since its 1956 debut. Reference 118238 presents the signature fluted bezel alongside a stunning blue diamond dial, a combination that projects both regal authority and chromatic sophistication. The vivid sapphire-toned dial with diamond hour markers delivers an unmistakable presence on the wrist.

At the heart of this timepiece beats the Calibre 3155, Rolex's self-winding perpetual movement offering a precision-regulated 48-hour power reserve. The movement incorporates a Parachrom hairspring for superior resistance to magnetic fields and thermal variation, a paramagnetic lever escapement, and Rolex's proprietary Microstella regulation system. The 36mm Oyster case in 18ct yellow gold is water-resistant to 100 metres, while the President bracelet — exclusive to the Day-Date — provides the quintessential three-piece link comfort that no other bracelet replicates.

For collectors, the 118238 series represents the final generation of Day-Date 36 references powered by the Calibre 3155 before Rolex transitioned to the 128xxx series with Cal 3255. That historical position — combining modern build quality with the last iteration of a celebrated movement architecture — gives this reference particular appeal to those who track the marque's evolutionary milestones. Blue diamond dials command consistent premiums, making this an especially compelling acquisition at both collector and investment levels.
