The Patek Philippe 6007A-001 is a 40 mm stainless steel Calatrava made in a run of 1,000 pieces in 2020. Fakes of it are common because the real watch trades well above its original retail price and most buyers never handle one in person. A replica of this reference fails in four places: case thickness, dial texture, the date aperture, and the movement visible through the sapphire back. Check those four points first, then verify the rest.
What the Real 6007A-001 Is
Patek built this watch to mark the opening of its new manufacture in Plan-les-Ouates, Geneva. It is the rare steel Calatrava with a display back, which is exactly why counterfeiters target it. Reference specs to memorize:
- Case: 40 mm stainless steel, height just under 10 mm, 30 m water resistance
- Dial: blue with a stamped, carbon-like texture, applied white gold numerals and hands
- Movement: caliber 324 S C, automatic, 4 Hz, 45 hour power reserve
- Back: sapphire display crystal, gold rotor, Geneva stripes, Patek Philippe Seal
- Strap: blue calfskin with white contrast stitching and a steel prong buckle
- Production: 1,000 pieces, announced 2020
Why Fakes of This Reference Stand Out
Most replica makers build one steel Calatrava case and reuse it across several references. That shortcut shows up as a thick case, a flat dial surface, and a movement that has nothing in common with a Patek caliber. The 6007A also has a textured dial that is hard to reproduce without the original stamping die, so the pattern on a fake looks printed or smeared under raking light.
Five Tells: Inspection Steps
- Measure the case height with calipers. A genuine 6007A sits under 10 mm. Most replicas run 11 mm to 13 mm and feel top heavy on the wrist.
- Tilt the dial under a lamp and look at the blue surface. The real texture has depth and shifts with the angle. A fake reads as a flat print job with a repeating pattern.
- Put a loupe on the date window at 3 o'clock. Patek uses a thin serif font on a crisp cut aperture. Fakes show a thick sans-serif date and a stamped edge with burrs.
- Check the applied numerals and hands. Genuine white gold markers have sharp polished bevels that flash from one side. Fake markers are plated brass with soft edges and uneven lume fill.
- Turn the watch over. A real 324 S C shows free-sprung balance, black polished bevels, and a solid gold rotor. Replicas use a Miyota or Seagull base with a screwed-on decorative plate and engraved text that does not match Patek finishing.
The Movement Is the Hardest Part to Copy
Caliber 324 S C uses Patek's own balance, hairspring, and finishing standard. No replica factory produces a working clone of it. If the seller shows a movement photo with a generic automatic winding bridge, an off-center rotor screw, or a balance with a regulator index arm, you are looking at a fake, regardless of what the dial says.
Price and Paperwork Reality Check
The 6007A-001 sold at retail for roughly 21,000 Swiss francs and now changes hands on the secondary market for well above that. Replicas sell for a few hundred dollars to about a thousand. A price near retail with a full box and papers set is not a bargain, it is a warning. Ask for the certificate, the original invoice, and a movement photo before money moves.
Before You Pay
- Confirm the reference number 6007A-001 is stamped correctly on the caseback
- Compare case height against published specs, not against seller photos
- Request a macro shot of the balance wheel and rotor
- Walk away from any listing that refuses a movement photo
