What the Nautilus 5711/1G is

Patek Philippe builds the Nautilus in three metals. The reference suffix marks which: 1A is stainless steel, 1G is 18k white gold, 1P is platinum. The 5711 case measures 40 mm across and 8.3 mm thick. Water resistance is 120 m. Caliber 26-330 S C replaced the 324 S C in 2019 and runs at 28,800 vph with a 45 hour power reserve. Patek fits a sapphire back, so the movement is visible. The company does not publish production counts or a separate thickness figure for the white gold version.

Is a Replica Patek 5711/1G Worth Buying?

The dial has horizontal embossed grooves, applied white gold markers, and a date window at 3 o'clock. The bracelet is integrated into the case and tapers toward a fold-over clasp.

Pick first: an automatic copy with a 40 mm case and 8.3 mm profile

Case dimensions decide the copy. Verify two numbers: 40 mm width and 8.3 mm thickness. Many copies measure 9 mm to 10 mm because the movement sits too tall. A build on a 28,800 vph automatic with a thin rotor comes closest to the 8.3 mm profile. Ask for a caliper photo of the case flank, not a wrist shot.

Weight follows the metal. The real 1G is solid 18k white gold. Most copies are steel with rhodium plating, so a copy weighs less. A jewelry scale settles that in one step.

Other options

Entry automatic, 21,600 vph

21,600 vph movements cost less and sweep slower. Case thickness lands near 9.5 mm. Dial groove depth is shallow, and the date wheel font differs from the Patek print.

Quartz copies

A quartz copy keeps the case thin, close to 8.5 mm, but the second hand ticks once per second. No mechanical parts show through the case back. Water resistance claims on quartz copies run 30 m or go unstated.

Seven checks: fake against real

  1. Weight. 18k white gold has a density near 15.5 g per cubic centimeter. 316L steel sits near 8.0. The gold case and bracelet carry more mass than a steel copy of the same size.
  2. Case thickness. 8.3 mm on the original. Measure at the case flank with a caliper.
  3. Dial grooves. The genuine dial has cut horizontal grooves with sharp edges and even spacing. Copies show rounded ridges and a soft surface.
  4. Date window. Patek bevels the aperture at 3 o'clock. Copies cut a flat hole and center the numeral off-axis.
  5. Bracelet fit. Genuine links move with tight tolerances. Gaps between links and a loose clasp are common on copies.
  6. Movement finish. Patek applies Geneva stripes, hand bevels and a gold rotor on many calibers. A copy shows stamped decoration and a plated rotor.
  7. Hallmarks. A gold Patek case back carries the 750 stamp for 18k gold plus Swiss assay marks, and the movement carries the Patek Philippe Seal. Serial and reference numbers sit on the case back and repeat on the movement.

Law and service

Federal law treats counterfeit watch sales as a crime. 18 U.S.C. 2320 covers trafficking in counterfeit goods. A first offense by an individual carries up to 10 years in prison and a $2 million fine. U.S. Customs and Border Protection seizes counterfeit shipments, and the personal import exemption does not cover counterfeit items.

Patek Philippe will not service, repair or authenticate a counterfeit. Auction houses such as Christie's, Sotheby's and Phillips do not list counterfeit watches, so a copy has no resale channel. Service on a genuine 5711 goes through Patek or an authorized service center and includes a movement overhaul and case refinishing.
