Description
This replica Day-Date 228239AF pairs a 40mm white gold case with a blue dial finished in a sunburst gradient that shifts from deep navy to lighter tones depending on the angle of light. The “AF” suffix in the reference indicates the Arabic numeral hour markers, which replace the more common Roman or baton indices found on other Day-Date variants. Arabic markers on a blue ground create a look that sits somewhere between formal and expressive, less traditional than Roman numerals yet more legible at a glance. The Day-Date remains the only model in this brand’s catalog to display both the day of the week and the date, spelled out in full through a window at twelve o’clock.

The white gold case gives this reference a cooler visual temperature than yellow gold versions. Under direct lighting the polished bezel catches reflections while the blue dial absorbs them, producing a contrast that photographs particularly well.
Caliber Breakdown
Day-Date movements handle two calendar complications simultaneously. The day wheel advances instantaneously at midnight, cycling through all seven days in the chosen language. The date changes in parallel through a separate disc. These dual displays require more mechanical coordination than a simple date-only movement, which is why the Day-Date earned the nickname “President” after heads of state were frequently seen wearing it. The Day-Date lineup traces this mechanical tradition back to 1956, making it one of the longest-running complication series in the industry. For a warmer alternative to this blue-on-white-gold combination, the champagne dial 228238 offers a different character entirely.
How It Compares
Within the 228239 family, dial color defines personality. The blue version here reads more contemporary than a silver or slate alternative, while the Arabic numerals add a layer of distinction that baton indices do not provide. On the wrist the 40mm case wears proportionally thanks to the relatively slim profile that Day-Date references maintain across generations. This replica Day-Date 228239AF delivers the full day-date complication in a color combination that balances modern appeal with the formality the President bracelet demands.
