Short answer
The name "Patek Philippe Aviator Travel Time" comes from replica sellers. Patek Philippe does not use it. The watch copied under that label is the Calatrava Pilot Travel Time, reference 5524G-001 in white gold and 5524R-001 in rose gold. Both launched as dual time zone travel watches. Replica listings that say "Aviator Travel Time" are describing the 5524.
The genuine 5524 in numbers
- Case: 42 mm, 18k white gold on 5524G, 18k rose gold on 5524R.
- Movement: caliber 324 S C FUS, automatic, 29 jewels, 45-hour power reserve, 28,800 vibrations per hour.
- Functions: second time zone, date at 6 o'clock, local time set with pushers at 8 and 10 o'clock.
- Dial: sunburst blue on 5524G, brown on 5524R. Gold applied numerals. Day and night apertures marked LOCAL and HOME.
- Caseback: sapphire display back. Rotor in 21k gold.
Movements inside replica 5524 watches
Most replicas of the 5524 use one of three setups: a Miyota 9015 with a bolt-on 12-hour module, a Chinese automatic with the same module layout, or a decorated movement built to look like the 324 S C FUS. All three add parts between the dial and the caseback. That stack changes case thickness, crown height, and how the pushers move the hour hand.
Case metal is 316L stainless steel with gold plating on most replicas. Density of 18k white gold sits near 15.5 grams per cubic centimeter. Steel sits near 7.9. The gap shows on a scale and in the hand.
Points that separate a replica from a 5524
- Movement finish. Genuine 324 S C FUS shows Cotes de Geneve stripes, circular graining, a Gyromax balance, and a Spiromax spring. Replica bridges show stamped lines, steel screws, and flat polishing.
- Rotor. 21k gold on the genuine watch. Brass or steel on replicas.
- Pushers. Genuine pushers have a short, firm throw. Replica pushers feel loose or grind.
- Hallmarks. Patek Philippe 18k cases carry gold hallmarks and a 750 stamp. Replicas stamp them or omit them.
- Date disc. Genuine disc print is sharp at 6 o'clock under a loupe. Replica discs sit low or off center.
- Dial print. The Patek Philippe signature is applied and raised. Replica signatures are flat print.
Legal status in the United States
18 U.S.C. 2320 covers trafficking in counterfeit goods. A first offense by an individual carries up to 10 years in prison and a $2 million fine. Import of a counterfeit watch is prohibited. U.S. Customs and Border Protection can seize and destroy the shipment. A buyer who resells a replica as genuine can face trademark claims under the Lanham Act plus mail fraud or wire fraud charges when the sale crosses state lines.
What is not known
No public data lists which factories build 5524 replicas or how many units ship. Sellers change suppliers without notice. Claims about "Swiss movement" or "1:1" quality come from the seller, not from testing. Patek Philippe does not publish service records for counterfeit watches and will not service one.
