Pick: a replica only if the calendar is real
Two watches share a dial layout and a name. They do not share a movement. The genuine Breguet Classique 5327 runs a perpetual calendar that tracks month lengths and leap years. Replicas sold at $300 to $900 carry modified chronograph movements or Asian clones. Most show day, date, and month, then need a manual reset at the end of February. Buy the replica as a visual prop. Do not buy it as a calendar.
Fake Breguet Classique Perpetual Calendar Comparison: Which Is the Best Replica?
Genuine Breguet 5327: what the money buys
- Case: 39 mm, 18k rose, yellow, or white gold, welded lugs, coin-edge band.
- Dial: hand-turned guilloche cut on a rose engine, Breguet numerals, secret signature.
- Movement: in-house self-winding calibre with a silicon escapement and about 46 hours of power reserve.
- Calendar: perpetual, with recessed correctors in the case band.
- Finish: hand-bevelled bridges, Geneva stripes, blued screws under a sapphire back.
- Price: US retail listings land between $75,000 and $95,000. Pre-owned examples trade 25 to 35 percent lower.
Replica: what changes
- Case: steel with gold plating at most price tiers. A gold case weighs about twice a steel case of the same volume, so the replica feels light in the hand.
- Thickness: 1 mm to 2 mm more than the genuine, because a base movement carries a calendar module on top.
- Dial: printed or stamped pattern, not engine-turned. Numerals sit thicker. Subdial spacing drifts.
- Movement: Asian clone, often on a modified Valjoux 7750 architecture. Rotor engraving is cosmetic and does not match Breguet finishing.
- Calendar: annual or complete calendar in most builds. The 1,461-day perpetual program is absent.
- Price: $250 to $900. Sellers who quote more for a "Swiss made" replica rarely show a Swiss movement.
Options, in order
- Genuine 5327, pre-owned. Papers and service records matter more than the box. Budget $1,200 to $2,000 for a factory service.
- Replica with a documented annual calendar. Ask for the movement name and a photo of the caseback. Expect one correction each February.
- Replica with faux subdials. Cheapest tier. The subdials are decorative or run off the main time train. Skip it if you plan to wear the watch daily.
Checks before paying
- Ask the seller for the movement calibre and the calendar type in writing.
- Request a weight in grams and a case thickness in millimetres.
- Compare subdial positions to a factory photo of the 5327.
- Note the legal side: US Customs and Border Protection seizes counterfeit watches at import, and trafficking carries criminal penalties under 18 U.S.C. 2320.
