Replica Patek Philippe Nautilus 5726/1A — 40.5 mm Annual Calendar, Black Dial on Steel
Video above shows the black-dial annual calendar. The black variant of the 5726/1A strips the colour from the dial and lets the complication layout dominate visually. Against a black field, the white text in the day/month windows at 12 reads with maximum contrast. Moon-phase disc at 6 stands out sharply — gold crescent on black sky against a black surround. Same caliber 324 S QA LU 24H inside: annual calendar advancing day, date, and month automatically through 30- and 31-day months. Only February needs manual correction.
Black-dial annual calendar on steel — maximum contrast for the complication indications. Day, month, moon phase all pop against the dark field.
Case & Dial
40.5 mm diameter, 11.3 mm thick. Steel octagonal bezel, alternating satin and polished bevels. Push-in crown. Sapphire caseback, AR-coated.
Black sunburst with horizontal embossed grooves. The grooves are visible only at raking angles — from head-on the dial reads flat black, which maximises the legibility of the white calendar text and subdial markings. Day and month at 12. Moon phase at 6. 24-hour sector between 7 and 11. Date pointer on perimeter. Applied steel baton markers with white luminous fill — the lume is the primary source of night-time readability.
Bracelet
Integrated 904L steel, satin centres, polished edges. Fold-over deployment with double pushers. Same bracelet as every steel Nautilus 5726. The black dial makes this variant more versatile for evening contexts than the blue or brown — black dials match anything from formal to casual without fighting other colours in the outfit.
Movement
