A fake Patek Philippe 3448 is a copy of the reference 3448, the first automatic perpetual calendar wristwatch. Patek Philippe built it from 1962 to 1981 in a 37mm gold case, and genuine examples sell in the six figures. That price gap shapes the market: most fakes are low-cost display replicas or franken watches pieced together from real and modern parts.

What is the Patek Philippe 3448?
The 3448 put a perpetual calendar inside an automatic watch for the first time. Patek kept the basic design for 19 years.
- Production: most sources put the total near 586 pieces, almost all in 18k yellow, white, or rose gold.
- Case: 37mm wide, thin bezel, solid gold back.
- Dial: day and month windows at 12 o'clock, date window at 6 o'clock, applied baton markers, no lume.
- Movement: caliber 27-460 Q, an automatic base with a perpetual calendar module and a gold rotor.
- Moonphase: not on the 3448. The related ref. 3449 added one, and only a handful exist.
Why are convincing fake 3448s rare?
Copying a 3448 is hard for the same reason it is valuable. The watch is small, thin, and mechanical in a way replica factories do not build.
Patek Philippe 3448 Copy Guide: Top Luxury Replicas to Own
A perpetual calendar module that fits a 37mm case and follows a 1960s layout costs real money to reproduce. Replica makers sell volume, and the 3448 is a niche model that few buyers outside auctions know.

The bigger risk is not a factory replica. It is a franken watch: a genuine case or dial paired with a reprint, a later movement, or refinished parts. Those reach the market as real watches, not as replicas.
How do you spot a fake Patek Philippe 3448 edition?
Case and metal
Start with size. A genuine 3448 measures 37mm across and sits thin on the wrist. Most replica perpetual calendars run 39mm or 40mm because the calendar module needs room.
Look inside the case back for the 18k hallmark and the case maker's stamp. Gold-plated steel shows brass at worn lug edges and feels light for its size.
Dial and calendar windows
Original dials have crisp printing, sharp aperture edges, and applied gold markers with real depth. Reprints show soft edges, wrong fonts, and paint where there should be metal.
The layout is fixed: day and month at the top, date at the bottom. Any extra window, sub-dial, or pusher is a warning sign.
Movement
The caliber 27-460 Q fills the case in a way modern clones do not. Look for the Geneva Seal engraving, the gold rotor, and the correct bridge shapes.
A converted ETA or a Chinese calendar module looks nothing like it. Open the back or ask for a clear macro photo before you buy.
Paperwork
Patek Philippe issues an Extract from the Archives for a genuine watch, and it lists the reference, case number, and date of sale. A 3448 without papers is not fake by default, but the extract settles the question.
What do replica 3448s get right and wrong?
A good replica captures the look at arm's length: gold tone, dial layout, and thin profile. Under a loupe, the differences show.
- Right: dial layout, case shape, and overall proportions on the better copies.
- Wrong: thickness, calendar operation, movement finish, and the sound of the rotor.
- Wrong: gold. Replicas use plated steel or brass, so weight and hallmarks give them away.
Replica 3448s run from a few hundred dollars to about a thousand for a decorated automatic. Genuine 3448s trade in the six figures at auction, and top examples go higher.
Real vs replica at a glance
- Case size: 37mm genuine, often 38mm to 40mm on a replica.
- Metal: 18k gold genuine, plated steel on a replica.
- Calendar: mechanical perpetual calendar genuine, annual or module-based calendar on a replica.
- Movement: caliber 27-460 Q genuine, modified ETA or quartz on a replica.
- Papers: Extract from the Archives available for genuine watches.
FAQ
Is the Patek 3448 a perpetual calendar?
Yes. It was the first automatic perpetual calendar wristwatch, and it tracks day, date, and month without correction for leap years.
How many Patek 3448 watches were made?
Most references cite around 586 pieces across 19 years of production, spread over yellow, white, and rose gold.
Did the 3448 have a moonphase?
No. The 3448 shows day and month at 12 o'clock and the date at 6 o'clock. The moonphase version is the ref. 3449, made in tiny numbers.
Can a jeweler tell a fake 3448 from photos?
Sometimes. Case size, hallmarks, dial printing, and movement architecture are visible in good macro shots, but an Extract from the Archives is the only clean proof.
Should I buy a replica 3448?
Treat a replica as a costume piece. It will not hold value, it cannot pass an inspection, and it should never be sold as a real watch.
