The Day-Date 36 128238 is the current-production 36mm Day-Date in yellow gold, running the in-house caliber 3255 and wearing the President bracelet that has been synonymous with the reference since 1956. It is the watch Rolex builds for collectors who want the traditional round-case Day-Date without the bulk of the 40mm variant, and the 3255 movement gives it a technical backbone that earlier Day-Dates lacked.
The 128238 launched in 2019, replacing the 118238 which had run since 2000 with the older caliber 3155. The jump to caliber 3255 was the defining change: longer power reserve (70 hours), improved Chronergy escapement, and better magnetic resistance. The reference is offered across an unusually wide dial palette, including meteorite, onyx, and lacquer options alongside more conventional champagne and silver dials, and various numeral styles.
Production is ongoing, so the reference continues to accumulate dial variants without mid-run changes that create distinct collector sub-categories.
Check the President bracelet closely: the semi-circular three-piece links are uncomfortable to replace and aftermarket examples are easy to spot by fit and finish at the clasp. Verify the dial originality carefully on meteorite and stone dials, which have been targets for swaps from lower-value dials. Confirm the case has not been polished; the lugs on the round case should retain their original brushed tops with polished flanks, and over-polishing is the most common deduction on pre-owned examples.
Prefer examples with the original warranty card and box, as this reference trades actively enough that full sets are not a rarity and unpapered examples sell at a discount accordingly. Service history on a watch this recent (2019 to present) is rarely relevant, but verify the movement has not been opened for anything other than an authorized service.
