Replica Patek Philippe Nautilus 5740/1G-001 — 40 mm Blue Sunburst, Perpetual Calendar
The 5740/1G-001 is the top-complication Nautilus — a Perpetual Calendar in white gold on an integrated bracelet. Caliber 240 Q with micro-rotor handles day, date, month, leap year, and moon phase without any manual correction until the year 2100. The “/1G” suffix means integrated white-gold bracelet. Patek Philippe fits a perpetual calendar into a case just 8.4 mm thick. That is 3 mm thinner than the annual calendar 5726. This replica Nautilus 5740 is finished in white-gold-tone plating over 904L steel: case, bezel, bracelet, clasp.
Perpetual Calendar in 40 mm, 8.4 mm thick — thinner than the Annual Calendar 5726 despite tracking leap years until 2100.
Case & Dial
40 mm diameter, 8.4 mm thick. The micro-rotor caliber 240 Q is what makes this possible — a flat perpetual-calendar movement that barely adds height over the time-only 5711. Octagonal bezel in white-gold tone, polished bevels, satin flanks. Recessed correctors in the case band. Sapphire display caseback, AR-coated.
Blue sunburst dial with horizontal embossed finish. Day at 9, date at 6, month and leap-year cycle at 3, moon phase between 4 and 5 through a lacquered aperture. Applied white-gold baton markers, luminous fill. The sunburst effect radiates from centre outward — lighter at noon, darker at the chapter ring.
Bracelet
Integrated white-gold-tone 904L steel, flush at the first link. Graduating widths, alternating satin and polished centres, fold-over deployment clasp. The weight sits close to the steel 5712/1A Moon Phase bracelet. Substantially different wrist feel from the rubber-strap Aquanaut — heavier and more formal.
Movement
Automatic, 21,600 vph, micro-rotor. 48+ hour power reserve. Perpetual calendar module tracks 28/30/31-day months and leap years autonomously. Through the caseback: Côtes de Genève, perlage, white-gold-tone mini-rotor. SuperClone tier: ±8 sec/day. Full specs on our FAQ page.
