A fake Patek Philippe 3445 is either a watch built from scratch to copy the vintage reference or a genuine case rebuilt with wrong parts. The real reference 3445 is an automatic calendar watch that Patek Philippe made from 1961 into the mid-1980s in yellow, pink, and white gold. Most fakes fall apart under three checks: the case and movement numbers, the calibre 27-460 movement, and the dial printing.

Reference 3445 Basics

Patek Philippe brought out the 3445 as its first automatic calendar watch made in series. It runs on calibre 27-460, an automatic movement with a gold rotor and a long service record. The case measures about 34 to 35 mm across, so it wears small on a modern wrist.

The date window sits at 3 o'clock. Plenty of dials print "water resistant" below the brand name, a leftover of the era when a gold watch with a date was meant for daily wear. Production ran past 20 years, so dial styles shifted along the way.

Case

Gold cases came in yellow, pink, and white, with yellow gold the most common. Hallmarks and the case number sit on the caseback and the inner lugs. Collectors expect the case number and movement number to sit in a matching range, though the exact gap varies by production year.

Movement

Calibre 27-460 has a bridge layout and finishing that a trained eye reads in seconds. Engraving on the bridges should be sharp and deep, not stamped or printed. A generic Asian automatic will not fit the case opening or line up with the dial feet of a real 3445.

Dial and hands

Original dial printing is crisp and sits slightly raised, with serif details that survive close photographs. Redials lose that sharpness and often carry the wrong signature style for the serial range. Hands should match the case metal and show even patina across both.

Signature and serial ranges

Watches from the 1960s carry "Patek Philippe & Co." on the dial, while later examples drop the "& Co." A signature that does not fit the serial range points to a redial or a counterfeit dial. The same logic applies to the caseback markings.

The Three Kinds of Fake 3445

  • Full counterfeit: a watch built in the last 40 years with a fake dial, fake case, and a substituted movement.
  • Marriage or franken: a real 3445 case or movement joined to parts pulled from another watch.
  • Redial sold as original: a real watch with a repainted dial, priced as if untouched.

The third type causes the most arguments. The watch is genuine in parts, yet value drops hard once a repaint is confirmed by a specialist.

How to Check a Patek Philippe 3445 Step by Step

  1. Read the movement number and the case number, then compare both against Patek's archive records.
  2. Photograph the movement and check the bridge shape, jewel count, and engraving style.
  3. Study the dial under a loupe for raised printing, correct fonts, and even patina.
  4. Inspect the caseback for correct hallmarks and for metal lost to heavy polishing.
  5. Confirm the crown matches the case metal and sits flush against the midcase.
  6. Ask for service records or an Extract from the Archives.

Red Flags to Walk Away From

  • Numbers that do not match Patek's records, or a seller who refuses to share them.
  • Dial print that looks flat, blurry, or too glossy.
  • Case edges rounded from years of polishing.
  • A price far below market for the metal and the condition.
  • Photos that hide the movement, the caseback, or the hallmarks.
  • Pressure to buy before an independent inspection.

Do Modern Replica Factories Make a 3445?

Not often. High-end replica production follows demand, and demand sits with the Nautilus 5711, the Aquanaut, and modern Calatrava models. A vintage 3445 copy needs a small-batch dial with printed text plus a movement that fits a 34 mm case, which costs more than most buyers will pay.

What you meet instead are old counterfeits from the 1970s and 1980s, plus franken watches built from loose parts. Both turn up on auction sites and classified listings, sometimes with patina added on purpose to look vintage.

What Do Real and Fake 3445 Watches Cost?

Genuine 3445 examples trade for thousands of dollars, with pink gold, white gold, and unusual dial versions at the top of the range. Condition moves the number more than the reference itself, since polish, dial originality, and paperwork all count. Auction archives from Christie's and Sotheby's give the clearest read on where prices sit today.

A counterfeit or franken 3445 often sells for hundreds of dollars, or for whatever a buyer hands over after missing the warning signs. That gap is why this reference draws sellers who misrepresent what they have.

Questions to Ask Before You Buy

  1. Can I see the movement number and the case number in one photo?
  2. Does the watch come with an Extract from the Archives?
  3. Has the dial been refinished or relumed?
  4. Is the case unpolished, and are the hallmarks crisp?
  5. Will you accept a return if an independent watchmaker finds a problem?

FAQ

Is the Patek Philippe 3445 automatic?

Yes. It runs on calibre 27-460, an automatic movement with a gold rotor. That movement is one reason the reference holds collector interest.

Does a genuine 3445 have a quick-set date?

No. The date advances when you move the hands forward past midnight until the disc turns over. A seller who claims a quick-set function on a 3445 is describing something the movement does not do.

How many 3445s did Patek Philippe make?

Patek Philippe has not published a production total for the reference, so any exact figure you see online is a guess. Serial ranges show the watch was built in steady numbers for more than 20 years.

Can a jeweler spot a fake 3445?

A watchmaker who handles vintage Patek can, because the bridge layout, engraving, and dial printing are hard to copy. A general jeweler who sells modern brands may not know the reference at all, so ask for a vintage specialist.

Should I buy a fake 3445 to wear?

That call is yours. Keep in mind that vintage fakes are built from old parts, so service history and water resistance are unknown. A modern replica of a current model will run better than a 40-year-old counterfeit.
