Answer in brief
A watch sold as a fake 1735 Grande Complication is not a copy of the Patek Philippe reference 1735. No factory outside Geneva has built a working grand complication with a perpetual calendar, minute repeater, and split-seconds chronograph packed into that case. What circulates falls into three groups: decorative quartz or low-grade mechanical watches with a printed dial, watches from other brands dressed up with Patek markings, and straight scams where the photos belong to a genuine auction piece. Treat any listing that promises full function at a low price as a misrepresentation.
Prerequisites before you evaluate anything
- Photos of the actual watch, not catalog renders.
- A written statement of what the movement does, not a brand name alone.
- A return policy and a payment method you can dispute.
- The asking price in context of the genuine market.
What the genuine reference 1735 is
Patek Philippe introduced the reference 1735 in 1989 for the company's 150th anniversary. It is a wristwatch-sized grand complication with a self-winding movement, a perpetual calendar, a minute repeater, and a split-seconds chronograph. Production stayed in the single digits by most published estimates, and the surviving pieces sit in museums and top-tier collections. The value comes from the movement, the case finishing, and documented provenance, not from the dial logo.
Step-by-step screening process
- Read the description first. If it says grand complication and later lists a battery or a quartz movement, close the page.
- Count the subdials and apertures. Compare them with reference photographs of the real 1735. Missing apertures or wrong positions show the dial is a print, not a complication layer.
- Zoom on the calendar apertures. On a genuine perpetual calendar the day, date, and month sit in crisp frames with correct spacing. On fakes the frames look stamped and the text sits crooked.
- Ask for a video with the repeater slide engaged and sound recorded. A minute repeater produces a low chime and a high chime in sequence. A fake produces nothing, or a recorded sound played over a speaker.
- Ask for a movement photo through the display back. Match the architecture to published images of the caliber. If the seller refuses, assume the movement does not match.
- Check case measurements. The 1735 is a small, thin dress watch, not a 44 mm sports case. Oversized listings with that name are a different watch with a swapped dial.
- Verify the serial and any paperwork against the brand archive. Patek Philippe will confirm a reference and production date for a fee.
- Reverse-search the photos. Scam listings reuse images from auction houses and forums.
Red flags
- Price far below the genuine market, paired with 1:1 or super clone language.
- No movement photo, no video, no serial.
- Seller pushes you toward wire transfer or crypto.
- Weight described in vague terms. A real gold grand complication has a specific heft.
- Listing copied word for word from a forum post or auction lot.
Cost and legal reality
Genuine reference 1735 examples trade for millions at auction when they appear. A replica at any price is not an investment and cannot be serviced by the brand. Counterfeit watches are subject to seizure at import in the United States, and the buyer loses both the watch and the money. Sellers who describe a counterfeit as authentic also expose themselves to federal deception claims. If your goal is a grand complication look on a budget, buy a legal homage from a recognized maker and keep your expectations aligned with the price.
