Short answer
An imitation Breguet Classic Perpetual is a copy of Breguet's Classique reference 5327 dress watch. The genuine piece runs a self-winding perpetual calendar with a retrograde date, day and month apertures, a leap year indicator and a moonphase. Almost every imitation drops at least one of those functions. Treat any listing as a case, dial and strap purchase, and confirm which calendar functions actually work before you pay.
Prerequisites
- Decide which calendar type you want: full calendar, annual calendar or true perpetual.
- Set a budget band before browsing so you compare like with like.
- Ask the seller for live photos and a short video of the hands moving.
- Check your country's import rules on trademarked goods before ordering.
How to inspect an imitation, step by step
- Look at the caseband. Genuine Breguet cases carry fine vertical fluting. Stamped copies show a flat or coarsely cut band.
- Turn the dial under a light. Engine-turned guilloché catches light in shifting bands. Printed patterns stay flat from every angle.
- Study the hands. Breguet hands are blued steel with a hollowed pomme tip. Copies are often painted or chrome plated.
- Check the date arc. A retrograde date sweeps across an arc and snaps back at the end of the month. If the pointer crawls in a circle, it is a standard date wheel.
- Read the day and month windows at the same time. They should advance together near midnight, not minutes apart.
- Find the leap year indicator. It shows 1, 2, 3 or 4, or an L, and it moves once per year. A printed disc that never moves is decoration.
- Examine the moonphase. An engraved disc with a clean edge beats a printed photo disc with visible dots.
- Test the correctors. Side pushers should shift the calendar without sticking or grinding.
- Weigh the watch in your hand. A thin perpetual case in steel or gold should feel dense for its size.
- Wind or shake it and set the time. A smooth sweep with no stutter points to a mechanical movement. One tick per second means quartz.
Calendar terms you need
A full calendar tracks the 31st day and needs a manual correction after months shorter than 31 days. An annual calendar handles the 30 day months but needs one correction each February. A perpetual calendar handles leap years on its own. Many imitations sold as perpetual are full calendars with an extra printed disc behind the dial.
Tells of a low grade copy
- Calendar windows printed on a flat disc instead of cut through the dial.
- Caseback engraving with uneven letter spacing or a generic serial number.
- No fluting and no coin edge on a plain polished bezel.
- Mineral glass with a visible green edge instead of sapphire.
- Correctors that sit proud of the case or are fused shut.
- Strap hardware with sharp edges and loose stitching.
Before you order
In the United States, Customs and Border Protection can seize a shipment of goods that copies a protected trademark, and the buyer carries the loss. Pay with a method that offers a dispute path, keep screenshots of the listing, and get the return window in writing. A seller who refuses a video of the calendar changing at midnight is telling you what you need to know.

Care and service notes
Keep the watch away from magnets, and set the calendar only between 6 a.m. and 6 p.m. on the dial. Adjusting a calendar mechanism while it sits in its change cycle can strip the gears. Have a watchmaker inspect a mechanical copy every three to five years, and test the gasket seal before any contact with water. Most copies ship with modest water resistance, so treat rain as the limit.
