Breguet Classique Tourbillon Reference 3657BA/12/9V6

Partially verified

The Breguet Classique Tourbillon is a manually wound wristwatch featuring a tourbillon complication. It is housed in a 39mm 18K yellow-gold case characterized by a fluted caseband and straight welded lugs. The watch features a silvered, solid-gold dial decorated with hand-applied guilloché patterns. An off-center time display sits at 12 o’clock with Roman numerals and blued steel open-tipped hands. Additional functions include a sector-shaped power-reserve indicator at 9 o’clock and a 24-hour day/night indicator labeled "Heures Diurnes" at 3 o'clock. At 6 o’clock is an exposed one-minute tourbillon carriage which also functions as the running-seconds indicator. The movement is the Calibre 560.1, which operates at 18,000 vibrations per hour and has approximately 50 hours of power reserve. This example comes with a black alligator leather strap and an 18K yellow-gold deployant clasp, along with original boxes and a Certificate of Origin.

Object description

Case and Dial Design

The timepiece is constructed with a 39mm 18K yellow-gold case, which includes a fluted caseband and straight welded lugs. These features are classic elements of the manufacturer's design language. The dial is composed of solid gold, silvered and finished with various hand-executed guilloché patterns.

The dial layout organizes several indications around an off-center time display located at 12 o'clock, which utilizes Roman numerals and blued steel open-tipped hands. The additional indicators include a power-reserve display at 9 o'clock and a 24-hour day/night function at 3 o'clock. The lower portion of the dial is dominated by the tourbillon at 6 o'clock.

Evidence for this section
  • “39mm 18K yellow-gold case features the manufacture’s familiar fluted caseband and straight welded lugs”
  • “solid-gold dial that has been silvered and decorated by hand with multiple guilloché patterns”
  • “The off-center time display at 12 o’clock features Roman numerals and thermally blued, open-tipped Breguet hands.”

Movement and Complications

The watch is powered by the manually wound Calibre 560.1 movement, which operates at a frequency of 18,000 vibrations per hour. It provides a power reserve of approximately 50 hours. The movement includes a Breguet overcoil hairspring, which is designed to improve timekeeping precision.

A prominent feature of the watch is the one-minute tourbillon visible at the 6 o'clock position on the dial. The tourbillon carriage acts as both the regulatory mechanism and the running-seconds display. The movement is visible through a sapphire exhibition caseback, which exposes the engraved architecture of the calibre.

Evidence for this section
  • “Powering it is the manually wound Calibre 560.1, operating at a traditional 18,000 vibrations per hour”
  • “The movement incorporates a Breguet overcoil hairspring”
  • “at 6 o’clock, occupying the most prominent position of all, is the exposed one-minute tourbillon, its rotating carriage also carrying the running-seconds indication.”

  • Are there specific design variations within the 3657BA reference that differentiate this serial number 1810 from others?
