Short answer

A fake Breguet 5287BR is a counterfeit of a rose gold Breguet Classique. The letters BR in the reference code mark the case metal as rose gold, so any copy built on gold plated steel is wrong before you look at anything else. Replicas copy the silhouette and the dial layout, but they miss on four points: case metal and weight, hand guilloche on the dial, heat blued hands with polished bevels, and a movement finished and engraved the way Breguet finishes its own. Work through those four areas and most copies fall apart in a few minutes.

What you are comparing against

The 5287BR sits in the Breguet Classique line, a dress watch family known for a fluted caseband, welded lugs with screw bars, a finely engine turned dial, and Roman numerals drawn in a style unique to the house. Confirm the exact variant before you judge anything, because Breguet has shipped the 5287 reference with more than one dial and calibre configuration. Case diameter, thickness, metal, and calibre number all come from Breguet's own specification page for that exact reference. Everything below is a comparison against that sheet, not against a memory of a photo you saw online.

Before you start

  • Calipers or a digital gauge
  • A 10x loupe
  • A small jewelry scale
  • Breguet's official specification page for the exact 5287 variant
  • A watchmaker who can open the case back and run a timegrapher

Steps

  1. Write down the case diameter, thickness, metal, and calibre number from Breguet's specification page for the exact reference.
  2. Measure the case with calipers and compare the numbers to your sheet, watching for a copy that runs one or two millimeters wide and noticeably thicker.
  3. Weigh the watch head on the jewelry scale. An 18k rose gold case is roughly twice as dense as steel, so a plated brass or steel copy feels light for its bulk.
  4. Examine the dial under the loupe. Engine turned guilloche shows crisp, evenly spaced lines that cross without wobble, while stamped copies show rounded ridges, shallow depth, and uneven gaps.
  5. Compare the numerals and the minute track to reference photos of the same variant, checking the shape of each Roman numeral and the spacing of the divisions.
  6. Look at the hands. Heat blued steel has a deep, uneven tone with a mirror polished bevel along the edge, while painted copies look flat and uniformly blue or purple.
  7. Check the case flank and case back for Swiss assay marks and a 750 gold stamp. Copies often carry none, or place them where the genuine case has no room for them.
  8. Read the case back engraving. Reference number, case number, and the Swiss Made marking should be cut deep and clean, not lasered shallow and gray.
  9. Match the case number on the back against the number stamped on the movement and the number printed on the certificate.
  10. Ask the watchmaker to open the back and inspect the finishing: Geneva stripes, chamfered bridges, polished screw heads, and the calibre engraving.
  11. Have the same watchmaker read the beat rate on a timegrapher and confirm it matches the specification for that calibre.
  12. Verify the box, certificate, and service records, then confirm the serial through an authorized dealer before any money changes hands.

Red flags that end the conversation

  • A price far below the going rate for a solid gold watch of this class
  • A seller who refuses an in person inspection by your watchmaker
  • Photos that avoid the case back, the hallmarks, or the movement
  • Gold plating worn thin at the lugs, crown, or buckle
  • Papers listing a reference code that does not match the watch
  • A Swiss Made marking that is printed on the dial or case instead of engraved

Ownership and legal reality

A counterfeit is not a cheaper version of the watch. It cannot be serviced by Breguet, it carries no warranty, and it has no resale market because no dealer will authenticate it. In the United States, importing or selling counterfeit goods is illegal and shipments are subject to seizure by Customs and Border Protection. If you want the look of a Classique on a budget, buy a legitimate dress watch from a brand that stands behind its product.

Bottom line

No photograph settles the question. A genuine 5287BR is confirmed by measurement, weight, hallmark, engraving, and a bench inspection of the movement. Run the steps in order and stop at the first failure, because a real rose gold Breguet will pass every one of them.
