Quick answer
Reference 14802ST is a steel Audemars Piguet Royal Oak Extra-Thin Jumbo released in 1992, 20 years after the first Royal Oak. The case is 39 mm wide and about 8 mm thick. The movement is caliber 2121, an automatic with 36 jewels that runs at 19,800 vph. Replica copies of the 14802ST exist. Most miss on three points: case thickness, beat rate, and dial texture. Check those first.
The genuine watch, in numbers

Public records for 14802ST production runs and dial variants are thin. The exact count for each dial color is not something I can confirm.
Check 1: case thickness
A genuine 14802ST sits near 8 mm. Many replicas measure 9 mm to 11 mm. The extra height comes from a thicker movement and a taller caseback. Measure with calipers before purchase. Ask the seller for a photo of the case between caliper jaws. A number typed on a spec sheet is not proof.
Check 2: movement and beat rate
Caliber 2121 runs at 19,800 vph, or 2.75 Hz. A sweep that looks smoother than 5.5 ticks per second points to a 28,800 vph movement. Common fits in replica 14802ST cases are the Miyota 9015 and Asian 2824 clones. Both beat at 28,800 vph. Both are reliable. Neither matches the genuine rate. A date that snaps over at midnight is another sign of a different movement. The 2121 changes date over a slower window.
Check 3: dial and date
The Petite Tapisserie dial is stamped, not printed. Squares sit on a raised grid with sharp edges and even depth. Replica dials show shallow squares, soft corners, or misaligned printing. Look at the date window. The disc color should match the dial base. Font weight should stay thin. A fat date font or a white disc on a blue dial is a tell.
Check 4: bracelet, caseback, crown
Bracelet links taper toward the clasp. Screws sit flush. Gaps between links run even. On the caseback, engraving depth stays consistent and the reference number reads 14802ST. Blurry laser etching points to a replica. The crown is screw-down. Turning it should feel smooth, with no wobble.
Price and legal notes
Replica 14802ST listings often run $250 to $700. A higher price buys a factory name, not always better specs. Import of counterfeit watches into the United States is illegal. US Customs can seize the shipment, and the buyer loses the money. Sale of counterfeits also exposes the seller to trademark claims under the Lanham Act. Buying carries risk in most countries.
