Only precious metals. That has been the Day-Date rule since 1956 — no steel, no two-tone, no exceptions. The 228239AF takes that exclusivity further by using platinum, the densest and rarest metal Rolex offers. At 40mm on the President bracelet with a blue dial and fluted bezel, this is the configuration most associated with heads of state and institutional leaders, which is exactly why the collection earned its “President” nickname decades ago.

The 228239AF Up Close: Case, Dial and Bracelet
Start with what makes this a Day-Date and nothing else: the day-of-the-week display at 12 o’clock, spelled out in full across an arched window. No other current Rolex model shows the day this way. The date sits at 3 o’clock under the Cyclops lens. Together, these two complications give the wearer a complete calendar glance without subdials, pushers, or additional crowns — the information simply appears in two clean apertures on the dial face.
The President bracelet is the other defining element. Its semi-circular three-piece links create a smoother, more fluid drape across the wrist than the angular Oyster or multi-link Jubilee. The concealed Crownclasp folds flat under the bracelet with no visible external hardware. The 40mm platinum case shares its dimensions with the gold versions but carries more weight on the wrist — platinum’s density of 21.45 g/cm3 versus gold’s 19.3 g/cm3 is perceptible. The blue dial pairs with the cool grey tone of platinum, and the fluted bezel adds light play without any color contrast.

Movement Options: Swiss vs Japanese
The Day-Date’s movement powers two calendar complications: a day wheel visible through the window at 12 o’clock and a date disc at 3. Both change instantaneously around midnight rather than gradually creeping between positions over several hours.
- Swiss Automatic — References the genuine Caliber 3255. 28,800 vph, approximately 70-hour power reserve. The instantaneous day-date change mechanism trips cleanly at midnight. Hacking seconds for precise time-setting. On the genuine 3255, the day display supports 26 languages — the mechanism here handles the English day display with the same snap-action changeover.
- Japanese Automatic — Miyota-based, 21,600 vph, approximately 40-hour power reserve. Day and date functions both operate via crown positions. Widely serviceable with standard watchmaker equipment. The day and date change occurs in the midnight window as expected.
Both movements wind automatically and set through the same crown positions. The Swiss option matches the 3255’s power reserve specification and provides the more decisive midnight changeover.
