The Patek Philippe Nautilus 7118/1200R is a 35.2 mm rose gold watch with an integrated bracelet and a self-winding calibre 324 S C inside. Counterfeits of this reference are common, and each one fails the same checks: case thickness, bracelet construction, dial texture, hallmark depth, and the movement visible through the sapphire caseback. Verify those five points and you can separate a fake from a genuine 7118/1200R in minutes.
What the Genuine 7118/1200R Is
- Case: rose gold, 35.2 mm wide, about 8.6 mm thick.
- Bracelet: solid rose gold, integrated into the case, with a fold-over clasp.
- Movement: calibre 324 S C, self-winding, 45-hour power reserve, 21,600 vibrations per hour.
- Dial: horizontally embossed pattern with gold applied markers or diamond markers, depending on the sub-reference.
- Caseback: sapphire display back with an engraved reference number.
Specifications differ between 7118 sub-references. Confirm the exact number in Patek Philippe's catalog before you compare anything.
How to Check a 7118/1200R, Step by Step
- Measure the case with calipers. The genuine case is 35.2 mm across and about 8.6 mm thick. Most fakes run thicker because the movement inside is deeper than the 324 S C.
- Turn the watch over and study the movement. The genuine calibre shows a 21K gold rotor with the Calatrava cross, Geneva stripes, and a Gyromax balance. Fakes show printed text on a plated rotor and a generic balance wheel.
- Run a finger along the bracelet edges. Genuine links are solid rose gold with satin-finished outer links and polished bevels. Fakes show casting lines, sharp edges, and a hollow feel.
- Read the clasp engraving. The fold-over clasp carries deep, crisp engraving of the Calatrava cross and the Patek Philippe name. Fakes use shallow laser etching that fades under a loupe.
- Inspect the dial under 10x magnification. The horizontal embossed pattern stays even across the whole surface, and the printed text has clean edges. Fake dials show a wavy pattern and fuzzy printing.
- Look for Swiss precious metal hallmarks and the maker's mark on the case. On fakes the stamps sit too shallow in the gold or are missing.
- Weigh the watch. A solid rose gold 7118/1200R weighs far more than a gold-plated or steel counterfeit of the same diameter.
- Verify the reference and serial number with Patek Philippe. Request an Extract from the Archives or bring the watch to an authorized retailer. This step confirms the piece, and nothing else does.
Where Replicas Fail Most Often
- Movement decoration and rotor weight
- Dial texture and printing sharpness
- Bracelet finishing and link fit
- Caseback engraving font and depth
- Dial color and gold tone
Before You Buy
Counterfeit watches are illegal to sell or import into the United States, and shipments can be seized and destroyed. If you are buying a pre-owned 7118/1200R, work only with a seller who supplies the original invoice, an Extract from the Archives, and a written return policy. Meet at an authorized dealer or a watchmaker who services Patek Philippe, and release no payment until the movement has been inspected.
