Yellow gold has been the Day-Date’s natural metal since 1956 — the year Rolex introduced both the model and the President bracelet. The M228238 in white dial is the purest expression of that lineage: 40mm of 18ct yellow gold, fluted bezel, semi-circular President links, and a clean white dial that lets the gold do the talking. Where the platinum 228239AF whispers its presence through weight alone, this yellow gold reference is visually unmistakable.

The M228238 Up Close: Case, Dial and Bracelet
The 40mm yellow gold case has measurable heft — gold is denser than steel by roughly 2.5 times, and the Day-Date uses it for every external component. The fluted bezel is machined from the same 18ct yellow gold as the case, with vertical grooves that create a distinctive play of light. Unlike aftermarket or two-tone configurations, every surface here is a single consistent metal. A Twinlock screw-down crown and sapphire caseback crystal maintain 100m water resistance.
The white dial provides maximum contrast against the warm gold surroundings. Applied yellow gold hour markers with Chromalight luminescent fill ensure legibility, while the day-of-week window at 12 o’clock spells out the full weekday name in an arc. The date aperture at 3 o’clock is magnified by the Cyclops lens. The President bracelet — exclusive to the Day-Date collection and precious-metal Lady-Datejust — uses semi-circular three-piece links that conform to the wrist, secured by the concealed Crownclasp for a seamless bracelet profile.
Movement Options: Swiss vs Japanese
Both automatic tiers drive the Day-Date’s dual-calendar complication: day display at 12 and date at 3.
- Swiss Automatic — 28,800 vph beat rate with approximately 70-hour power reserve. Quickset day and date via the crown in dedicated positions. References the genuine Caliber 3255 specifications, including the paramagnetic blue Parachrom hairspring and Chronergy escapement for improved shock resistance and energy efficiency.
- Japanese Automatic — Miyota-based at 21,600 vph with approximately 42-hour reserve. Day and date quickset functions operational. Any independent watchmaker can perform routine service without requiring specialized parts.
Both options wind automatically through a bidirectional Perpetual rotor and operate via the Twinlock screw-down crown. The Swiss tier reproduces the Caliber 3255 operating characteristics most faithfully, including the 70-hour reserve between full winds.
