Short answer
A genuine Breguet 3358BR is a rose gold Classique with a hand-wound movement. Most replicas sold under that reference use a mass-produced ebauche in a plated case. The giveaway is not the name on the dial. It is the weight, the depth of the engraving, the engine-turned pattern, and the finish on parts you can only see with the watch face down.
What the code 3358BR means
Breguet reference codes end with a metal suffix. BR stands for rose gold, BA for yellow gold, BB for white gold, and PT for platinum. A listing that calls a 3358BR "stainless steel" or "gold plated" has contradicted itself, and that is your first filter when you scan photos.
Prerequisites
- A 10x loupe
- Digital calipers
- A scale accurate to 0.1 g
- Macro photos of the dial, caseback, and movement
How to inspect the watch
- Weigh the watch head. A solid rose gold case at this size carries real mass. A plated replica feels light in the hand and reads low on a scale.
- Measure the case across the bezel and lug to lug, then compare against the published spec for the reference. Replica cases are often 1 to 2 mm off.
- Study the caseback engraving. Genuine engraving is cut, so letters have depth and an inner wall that catches light. Laser etching looks flat and shallow.
- Check the dial guilloché. Hand-turned patterns show a slight break where the engine turning stops at the chapter ring. Replica dials print the pattern and the lines run uniform to the edge.
- Inspect the hands under the loupe. Breguet hands are blued steel with a polished bevel and a round eye. Plated hands show a rough edge and a flat painted blue.
- Look at the case flanks and lugs. Genuine cases get file work and hand polishing that leaves crisp straight bevels. Replicas round the bevel off during buffing.
- Turn the watch over and read the movement. Look for perlage on the mainplate, Côtes de Genève on the bridges, blued screws, and polished steel. Mass-produced ebauches show tool marks and printed lettering.
- Ask for the movement number and the case serial in one photograph. A seller who will not put both in the same frame is not selling what the listing describes.
Price signals
A rose gold case has a floor price set by metal value alone. If a listing asks a few hundred dollars for a watch described as solid rose gold, the metal is plated and the claim is false. Compare the asking price with the scrap value of the stated gold weight. Replica sellers who describe the piece as a replica at a replica price are at least being honest about what it is.
Questions to ask a seller
- What is the exact case diameter and thickness?
- Is the movement hand-wound or automatic?
- Is the case solid gold, gold filled, or plated?
- Can you send a photo of the movement number and case serial together?
- Do you accept a return if an independent watchmaker confirms the case is not gold?
Answers to those five questions separate a replica that is honestly described from one that is dressed up as the real thing. Buy from the first kind.
