Replica Patek Philippe Nautilus 5726/1A — 40.5 mm Annual Calendar, Dark Blue Dial on Steel
Video above. The dark-blue variant of the 5726/1A pushes the standard Nautilus blue deeper — closer to midnight navy than the classic blue-black gradient. The distinction matters on the annual calendar face because the darker base changes how the four complication indications render. The day/month windows at 12 show white text on a deeper blue field. The moon-phase disc at 6 blends more with the dial colour. The overall effect is subtler and more evening-oriented than the standard blue-dial 5726.
Dark blue annual calendar — deeper than the standard Nautilus blue, closer to midnight navy. Same four complications, different tonal register.
Caja y esfera
40.5 mm diameter, 11.3 mm thick. Steel octagonal bezel, satin and polished. Push-in crown. Sapphire caseback, AR-coated.
Dark blue sunburst with horizontal embossed grooves. The gradient barely shifts — it stays in the midnight-navy range from centre to edge, unlike the standard blue which lightens at centre. Day and month windows at 12. Moon phase at 6 with gold crescent on navy sky. 24-hour sector between 7 and 11. Date pointer on the perimeter. Applied steel baton markers with luminous fill. The dark blue absorbs more light than the standard blue, making the embossed grooves less visible in dim conditions.
Pulseras
Integrated 904L steel. Satin centres, polished outer edges. Fold-over deployment, double pushers. The dark blue dial against polished steel bezel creates a high-contrast frame that emphasises the octagonal shape more than lighter dials do. Same bracelet architecture as all steel 5726/1A variants.
