Short Answer
Breguet builds perpetual calendar tourbillon watches in its Grande Complication line. Genuine examples sell for $150,000 and above. Replicas sell for $300 to $1,500. Most replicas do not contain a real perpetual calendar. A replica tourbillon is often a working cage driven by a Chinese movement. Buyers get the look. They do not get the calendar math.
What the Genuine Watch Does
Abraham-Louis Breguet patented the tourbillon on June 26, 1801. The device places the escapement and balance inside a rotating cage. Breguet applied a perpetual calendar to watch No. 160, finished in 1827.
A perpetual calendar tracks 28, 30 and 31 day months and adds February 29 in leap years. It needs no date correction until 2100, because 2100 is not a leap year. A genuine piece carries a hand-turned guilloché dial, a hand-finished movement, solid gold or platinum, and a numbered certificate.
What Replica Watches Contain
- Movement: modified Chinese automatic or hand-wound caliber. Many builds have a working tourbillon cage.
- Calendar: day, date and month discs on a 31-day cycle. Leap year correction is missing.
- Case: 316L stainless steel with gold plating. Plating thickness runs 3 to 5 microns.
- Crystal: sapphire with anti-reflective coating on better builds. Mineral glass on cheap ones.
- Dial: machine-stamped guilloché pattern. Genuine dials are hand-turned on a rose engine.
- Water resistance: 30m to 50m on spec sheets. Do not test it.
Calendar Types to Know
Three terms get mixed up. An annual calendar corrects once a year, in February. A full calendar has no leap-year logic. A perpetual calendar has leap-year logic. Replica listings call a full calendar a perpetual calendar. Ask for a photo of the leap-year indicator or the movement code before payment.

What Is Unknown
Replica movement origins change between batches. Serial numbers do not exist. Two watches from one seller can differ. Long-term service support is not guaranteed. Independent watchmakers may decline to service replica movements. Breguet does not publish repair data for replicas, so a service quote before purchase is hard to find.
