On the full steel bracelet, the white-dial Patek Philippe Nautilus 5726/1A-010 Annual Calendar replica is the catalogue form of the light-dial 5726, its navy moon disc sitting at six. This white-dial Nautilus 5726/1A-010 replica packs annual calendar and moon phase complications into the Nautilus case without sacrificing the sport-watch identity. The 5726/1A reference adds day, date, and month displays alongside a moon phase indicator, all arranged symmetrically across the dial. At 40.5mm it sits half a millimeter wider than the standard 5711, accommodating the additional complication subdials while keeping the case visually consistent with the rest of the collection. The date sits in its own window at 6, and our page on the date font used on Nautilus calendar windows explains what a clean print looks like.

One Correction a Year, on the Genuine

Annual calendar is the sweet spot between a simple date and a perpetual calendar. On the genuine watch it automatically adjusts for months with 30 and 31 days, requiring one manual correction each year at the end of February. The clone reproduces the displays; ask for a function video to see how its calendar advances before you buy.

A White Dial That Shows Every 5726 Window

The annual calendar module sits on top of the base automatic movement, adding the day and month displays through two apertures under 12 o’clock and the date through a third window at 6, in the lower half of the dial. The moon phase indicator occupies a subdial near 6 o’clock, showing the lunar cycle; on the genuine calibre it drifts by one day every 122 years. Patek Philippe designed this layout to maintain dial legibility despite the additional information. The horizontal embossing still runs across the full dial face, unifying the complications into the Nautilus visual language. For a similar complication set with a darker aesthetic, the 5726/1A-014 dark dial variant provides the same movement in a different visual package. Both live within the Nautilus range as the complication-focused options.

Between the 5711 and the 5740

The 5726 occupies territory between the time-only 5711 and the grand-complication 5740. It offers meaningful mechanical sophistication without the price premium or servicing complexity of a perpetual calendar. The stainless steel construction keeps it accessible within the collection hierarchy. On the genuine calibre, moon phase accuracy of 122 years between corrections demonstrates the movement engineering behind what looks like a simple sport watch. This white 5726/1A-010 replica delivers annual calendar displays and moon phase on a platform designed for daily wear.
