Short answer
The Patek Philippe 5935A-001 is a steel World Time Flyback Chronograph. Replicas of it are sold under labels like "first copy" or "super clone." None of them reproduce the watch. The case, dial, and bracelet can be machined to look right in a listing photo. The movement, which is the entire reason this reference exists, cannot be copied at that price. If you are searching for a replica 5935, the useful thing to know is what you would actually receive and what the risks are.
What the 5935A-001 actually is
Patek released it in 2022 in stainless steel, roughly 41mm, with an opaline rose gilt dial and caliber CH 28-520 HU. That movement pairs a world time system with a flyback chronograph. The layout is the hard part: 24 city names, a 24 hour ring, and two chronograph registers on one dial without it turning to mud. Very few references in any catalog do this.
Where the replica story breaks down
Cosmetics are a machining problem. Function is a watchmaking problem. A real world time mechanism advances the city disc in lockstep with the hour hand, and it stays aligned through setting. A flyback chronograph needs a column wheel or an equivalent control system plus a vertical clutch so the seconds hand starts without a visible jump.
Most replicas run a generic automatic with a fixed 24 hour ring printed on the dial and a standard chronograph module. The city disc does not track the hour. The flyback does not fly back. So the one feature you are paying for is the first thing missing. "First copy" is a seller's label, not a grade. There is no factory standard behind it.
The legal side in the US
Goods carrying a counterfeit trademark cannot be imported or sold here. Shipments get seized, and trademark owners can pursue sellers directly. Buying one for personal wear carries less exposure than selling, but it is not zero, and the resale value is zero.
What I would do instead
If the world time layout is what pulls you in, there are honest options at real prices from brands like Frederique Constant, Farer, and Montblanc. If you want the 5935A itself, it is an allocation piece, and the grey market is expensive because the watch is real. This guide is not a green light to buy counterfeits. It is a warning about what shows up in the box.
